evk402 |
EVK402 is a simple single step digital thermoregulator (with defrost management); a second relay (alarm relay) allows to signal at a
distance working conditions outside the safety limits. The instrument is provided with one measure input both for PTC and NTC probes (room probe) and with one digital input (multipurpose); it is also available the J (thermocouple) version for J/K thermocouples and the M (multiprobe) version for PTC/NTC probes, J/K thermocouples, 2/3 wires Pt 100, Pt 1000 and Ni 120 probes, 0-20/4-20 mA and 0-10/2-10 V transducers (universal measure input) Some configuration parameters allow to set the output for "cooling" or "heating" action, to protect the load against overloads, to manage the defrost according to the requirments, etc A communication port (available by request) allows the communication with supervision systems (via TTL, with MODBUS communication protocol) or with the programming key EVKEY EVK402 frontal size is 75 x
33.5 mm (W x H) and has been studied for panel mounting.
