Comet H4531 Thermometer with Ethernet Interface and Relays
- Dew point and computed quantities
- Relay outputs
- Binary inputs
- Dual line LCD
- Ethernet interface
- ModbusTCP protocol
- SNMP protocol
- SNMP Trap
Sensor H4531 is designed for online monitoring of temperature. Three binary inputs to detection of two-states signals are the advantage. Other devices are controlled by two relay outputs.
Programmable regulators with Ethernet connection a re-designed to measure temperature, relative humidity and barometric pressure of air in non-aggressive environment, to alarm indication and to control of external devices. Three galvanic no isolated binary inputs are intended for detection of binary signals. Regulators are available in wall-mount version or with probe on a cable. Type H3531P is designed for measurement 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 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 Ethernet too. The instrument may send a warning message if the measured value goes out of adjusted limits. Devices are equipped with four button keyboard and LCD display.
