EH3-Electronic humidistat and controller - Seibu Giken DST AB - #1

Text version of the page

The EH3 can regulate and mo ni tor: • Relative humidity % RH • Absolute humidity g/kg • Dew-point °Cdp • Temperature °C / K / °F Two closing contacts: Possible to choose source from one of the four parameters above to each relay. Used for controlling one dehumidifi er in two steps or to control two separate dehumidifi ers. Can also be used for dehumidifying on one relay and tem pe ra tu re control on the other. Display and diodes: 2 row display where two parameters can be monitored. Green “Normal” diode and red “Alarm” diode, switches at a set value of any of the four parameters. Analogue outputs: 2 outputs with Vdc or mA, choose source from the PI-regulator or one of the four pa ra me ters above. PI-regulator: Controls energy-saving on a three phase dehumidifi er or a valve for a cooling coil. Set relative humidity, absolute humidity, dew-point or tem pe ra tu re and EH-3 will keep it constant. Sensor: Capacitive type moisture sensor from Honeywell with an accuracy of <±2%RH and <±0,5° C. Each sensor comes with a calibration protocol. EH3 - Electronic humidistat and controller ONLY AVAILABLE FROM DST!
