Temperature and Humidity Regulator w/RS485 Output
Humidistat, thermostat with two relay outputs. Outdoor, indoor use.
Relative humidity, temperature probe on a cable. Measured values are also converted to other humidity interpretation: dew point temperature, absolute humidity, specific humidity, mixing ratio, specific enthalpy. Three two-state inputs. The device is supplied with a T+RH probe with 1m cable. Cable lengths 2m or 4m are available optionally. Humidistat is designed for two-state control of e.g. heating, ventilation, humidifier, dehumidifier, etc.
Transmitter is equipped with two relay outputs for alarm indication or control of external devices. Each relay can be assigned to any measured or computed value. For each relay setting of delay, hysteresis, an audible alarm is enabled.
Measured temperature and relative humidity are recalculated to other humidity interpretations - dew point temperature, absolute humidity, specific humidity, mixing ratio, or specific enthalpy.
Parameters are easily adjustable from regulator keyboard or from the computer. Large dual line LCD for simultaneous display of temperature, relative humidity, or other calculated humidity interpretation is an advantage.
State-of-the-art capacitive polymer sensor ensures excellent calibration long-term stability, inertia against water and condensation. Transmitter is designed for use in a non-aggressive environment.
Transmitter is also equipped with three binary inputs for detection of two-state events - e.g. water, smoke, glass break detection, door contact.

- Programmable regulators
- with RS485 galvanic isolated serial interface are designed to measure temperature, relative humidity, and barometric pressure of air in a non-aggressive environment, to alarm indication, and to control external devices. Three galvanic no isolated binary inputs are intended for the detection of binary signals. Regulators are available in wall-mount, duct-mount versions, or with a probe on a cable. Type H3431P is designed for measuring the temperature and relative humidity of compressed air.
- The function of two output relays
- can be set from regulator keyboard (or from computer) and using the jumpers (see "Electrical wiring"). You can assign one of the measured or computed value (dew point temperature, absolute humidity, specific humidity mixing ratio, and specific enthalpy) to each relay. The setting of delay, hysteresis, and audible alarm is enabled for each relay. The status of output relays can be controlled remotely via the RS485 link too. Devices are equipped with a four-button keyboard and two-line LCD display.
- Regulators support
- Modbus RTU protocol and protocol compatible with standard Advantech-ADAM.
