EVK422
|
EVK422 is a digital controller able to manage the activity of refrigerated units dedicated to milk storing. The instrument has got two
relays (compressor and agitator) and can work both PTC and NTC probes. A communication port (available by request) allows to connect the instrument to the supervision system (via TTL, with MODBUS communication protocol) or to the programming key EVKEY.
