Specification :

Digital Humidistat Eliwell Type 912/R controllers have one point of intervention only and can be used for temperature (IC 912), relative humidity (IC 912/R) and pressure (IC 912/P) control, provided for ON–OFF operation.
Some models have an input for PTC/NTC thermostatic probes or for Pt100/Tcj/Tck probes, EWHS280/300/310 humidity probes, for EWPA007/030 pressure transducers, for 0/4..20 mA, 0..1/5/10 V current and voltage signals (selectable with a parameter).

The values measured by the probes are displayed with three and a half digits and a minus sign. All models have TTL connections that enable the controllers to be used withCopy Card, the quick programming accessory.

The IC 912LX version includes a connection for TelevisSystem, or alternatively for networks with ModBUS protocol.
