IC 901
IC 912 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
