The two-degree-of-freedom (2-DOF) algorithm can accurately reach the set temperature (SV) and respond quickly to disturbances for accurate and precise temperature control.

Users can choose between two model types for optimal control in various environments. Program control models offer pattern control with easy parameter settings and fixed control models offer a timer functions.

Program control models can be used to easily set the control pattern by sequentially setting the target temperature and time of each step. Users can easily draw the pattern with DAQMaster software by clicking the coordinates of the time-temperature graphs.

Fixed control models can be used to preset the operation time by delaying the On/Off control outputs or by maintaining the PV for a set amount of time. 

Various control function including Group PID, Zone PID, and Anti Reset Windup (ARW) available for optimal PID control in various environment.

Users can set up to 10 events such as PV high/low limit, disconnection, and control operation notification. Logic operation results can be transmitted with relay alarm output and real-time monitoring is possible via RS485 communication.

Users can select from ON/OFF control, cycle control, and phase control using the standard SSR drive output option. Precise and accurate control is possible at low costs.

The controllers feature ladder-less and RS485 communication that can communicate with master devices (PLCs) without extra ladder programming.

The SV and Run/Stop status of the master device can be synchronized with up to 31 slave devices to simultaneously control multiple zones.
