Yokogawa YPP6060 - Dual Line, 6-Digit Dual Input Process Meter

Dual-Input Process Meter

The YPP6060 has two process input channels (A & B) capable of accepting current (0-20, 4-20 mA) and voltage (±10, 0-5, 1-5, 0-10 VDC). Each input is programmed separately, with independent input type selection and scaling. These inputs may be displayed individually as part of the customizable dual-line display, or used with a wide range of math functions. Each input has a custom unit or tag that may be displayed. A 24 V transmitter power supply is standard and may be used to power the inputs.

Powerful Math Functions

The YPP6060 uses two process input channels (A & B) in a variety of powerful math functions designed for a wide range of process applications. Programmable adder (P) and factor (F) constants allow each formula to be customized as needed for a specific application. The math function (C) may be displayed with units, tags, channel A or B, and in other useful combinations.
 

Optional SunBright Display Models

PROPLUS’s SunBright display models have an extraordinarily bright LED display. They are perfect for applications where the meter is in direct sunlight or in applications where visibility may be impaired by smoke, fog, dust, or distance.

Max/Min Display

Max/Min (or Peak/Valley) is standard on the PROPLUS YPP6060. Either display can be configured to show either input’s maximum or minimum value since last reset. The displays can also be configured to toggle between Max and Min values. Both values can be simply reset from the front panel.

Customizable Displays

The PROPLUS has two red LED displays, an Upper display 0.60" (15 mm) high, and a Lower display 0.46" (12 mm) high. Each display is a full 6 digits (-99999 to 999999).

The displays can be set up to read input channels (A or B), math function channel C, toggle between A & B, B & C, A & C, A & B & C, toggle between channels A, B, or C & units, the max/min of any of the channels, including the math channel (C), set points, gross (without tare) or net (with tare) & gross values of channel A or B, or the Modbus input. This allows the display to be setup to display whatever variables are most valuable to the application. Here are just a few examples.

Alternation Display

Certain display options alternate the display information. A single display can show input variable information as well as that channel’s unit or tag. Input and math function channels, gross and net values, and select inputs and the math result may also alternate on a single display. Below are just a few of the options for setting up a single display to alternate information.

Function Keys

There are three function keys available to the user. These keys can be programmed to trigger certain events (i.e. acknowledge alarms, reset max and/or min, disable/enable output relays, or hold current relay states), provide direct menu access points, and more.

Rugged

A unique front panel design makes the PROPLUS nearly impenetrable in typical applications. Here, the PROPLUS easily survives a direct hit on the display from a heavy 2" solid stainless steel ball dropped from eight feet.

Easy to Use

The user friendly dual-line display makes the PROPLUS easy to set up & program. No jumpers to set for input selection. All setup & programming are done via the front panel. Three levels of password protection help maintain the reliability of the programming.

Three Tier Password Protection

The PROPLUS offers 3 levels of password protection:

• Level 1 protection allows the operator use of only the 3 pre-configured function keys on the front panel without a password.
• Level 2 protection allows the operator use of only the function keys and the ability to change set points without a password.
• Level 3 protection restricts the operator from using the function keys and all meter configuration menus without a password.

Advanced Linearization Capability

The PROPLUS includes a 32-point linearizer. In non-linear level applications (i.e. some pumping or lift stations), it can easily compensate for submerged equipment or plumbing that displace usable volume. A second independent 8-point linearizer is available for a second scaled display (PV2) when “Level” function is enabled. Yokogawa’s free PROPLUS PC-based software greatly simplifies the construction of the linearization tables. The software can save this data to the meter and/or PC.

On-Board Digital Input

The YPP6060 includes a digital input as standard. This digital input can operate with the tare, reset tare, or interlock relays feature, force relays on from a signal from a PLC or relay on other equipment, and much more. This is ideal for installations where the meter is inaccessible behind a cover, or where an additional function key is needed for customized operation.
 

Rounding

The rounding feature is used to give the user a steadier display with fluctuating signals. It causes the display to round to the nearest value according to the rounding value selected (1, 2, 5, 10, 20, 50, or 100). For example, with a rounding value of 10, and a input of 12346, the display would indicate 12350.

Modbus ® RTU Serial Communications

With the purchase of a serial communication adapter, PROPLUS meters can communicate with any Modbus Master device using the ever-popular Modbus communications protocol that is included in every PROPLUS. This greatly increases the flexibility of the meter. Modbus provides much more capability than read PV and write set points. Below are some examples of other things that can be done with PROPLUS’s Modbus communications.

• Send a 6-character message to the lower display upon an event
• Convert a digital value to a 4-20 mA signal
• Remote user control (i.e. change set points, acknowledge alarms)
• Input a Modbus digital PV (in place of analog input)
• Remote override of any, or all, relays and analog outputs

Meter Copy

The Copy feature is used to copy (or clone) all the settings from one PROPLUS to other PROPLUS meters in about 20 seconds! The Copy function is a standard feature on all meters. It does not require a communications adapter, only an optional cable assembly, P/N YPPA1200. See the ordering information for complete details.

PROPLUS SOFTWARE

Configure, monitor, and datalog a PROPLUS YPP6060 from a PC using PROPLUS Software (available for download at www.yokogawa-usa.com) and a serial adapter.

FIELD EXPANSION MODULES

Add functionality to the PROPLUS in the field with easy-to-install external expansion modules. Add USB, RS-232, or RS-485 communications, I/O modules (up to 2), and 4-relay expansion module. The menu items for these modules do not appear until the module is connected, simplifying the basic menu. Relay and digital I/O modules are shown below with optional DIN rail mounting kit, P/N YPPA1002.
 

YPPA1044 I/O Expansion Module

Four digital inputs and four digital outputs are available per expansion module. The PROPLUS meter will accept two of these modules. External digital inputs can function similarly to the front panel function keys or on-board digital input F4. They can be configured to trigger certain events (i.e. acknowledge/reset alarms, reset max and/or min values, disable/enable all output relays, and hold current relay states), provide direct menu access point, or mimic front panel keys. The I/O module can be used to configure the PROPLUS remotely, in essence giving the user control of the four front panel push buttons. This feature is particularly useful if the meter is mounted inside an explosion-proof enclosure.

Digital outputs can be used to remotely monitor PROPLUS’s alarm relay output states, or the states of a variety of actions and functions executed by the meter.

YPPA1004 Relay Expansion Module

An external module containing four 3 A Form A (SPST) relays can be added to the PROPLUS at anytime. Removable screw terminal blocks accept 12 to 22 AWG wire.

YPPA1232, YPPA1485, & YPPA8008 Communication Modules

Serial communications on the PROPLUS can be added anytime with external YPPA1232 (RS-232) or YPPA1485 (RS-485), or YPPA8008 (USB) communication adapters.

Relay Outputs

The PROPLUS has up to four 3 A Form C relays (SPDT) with multiple power loss fail-safe options. Each relay may be assigned to input channel A or B, or math result (C). Relays can be configured for proper protective action upon input loop break. Relay ON and OFF delay times are user adjustable. Up to eight front panel indicators show alarm and/or relay state. All relays can be configured for 0-100% deadband.

Replay Operation/Configuration

There are powerful relay functions that can be configured in the PROPLUS meter, including:

Analog Output

The isolated analog retransmission signal can be configured to represent process input channel A or B, math result (C), max or min for channel A, B, or highest or lowest max or min of A and B, set points 1-8, Modbus input, or manual control mode. While the output is nominally 4-20 mA, the signal will accurately accommodate under- and over-ranges from 1 to 23 mA.

Manual Output Control

Take control of any output with this feature. All relays can be forced ON or OFF, and the 4-20 mA output signal can be set to any value within its range. When the relays and 4-20 mA output are controlled manually, an LED labeled “M” is turned on and the associated Alarm LEDs (1-8) flash every 10 seconds indicating that the meter is in manual control mode.

Isolated Transmitter Power Supplies

A powerful 24 V @ 200 mA power supply is a standard feature on the PROPLUS meter. It can be configured for 5, 10, or 24 V (default) by means of a simple internal jumper (see manual). An additional power supply (24 V @ 40 mA) is standard with the 4-20 mA output option.

Sampling Function (PV Triggered Timed Relay)

The sampling function allows the operator to set a set point for a “sampling” relay. The relay can be assigned to input channels A or B, or the math result (C). When the PV reaches that set point, it will close that relay’s contacts for a preset period of time (0.1 to 5999.9 seconds). An example of its use may be for beer/ale fermentation. When the batch reaches a certain pH, the relay contacts would close and alert someone or automatically take a sample of the batch. This function can be used whenever a timed relay output closure is required when the PV reaches a certain set point.

Interlock Relay(s)

This function allows a process to use one or more very low voltage input signals or simple switch contacts to control the state of one or more internal “interlock” relays. A violation (i.e. loss of input, open switch, or open circuit) forces one or more N/O interlock relay contacts to open. One input can be used in series with a number of interlock switches, or up to eight inputs can be required to force-on one (or more) internal interlock relays. Please see Application Note AN-1008 on our website for more information. Requires YPPA1044 Digital I/O module or use of on-board digital input F4.

SIGNAL INPUT CONDITIONING

Non-linear input signals (i.e. weirs & flumes, differential pressure, etc.) can be linearized with the PROPLUS’s simple to use built-in signal input conditioning, such as: square-root extractor, exponential linearizer, horizontal round tank linearizer, or the PROPLUS powerful general purpose 32-point linearizer.
