DEVIreg Multi

7-channel DIN-rail controller

Image: DEVI

DEVIreg™ Multi is a 7-channel electronic programmable controller for DIN rail installation. Every channel can be set up individually with three control modes: with a temperature sensor, time-proportional power regulation without a sensor, or manual on/off with a time limit. Channel inputs can be selected via software between 8 types of temperature sensor, including NTC 15 kΩ at 25 °C. A Modbus RS485 opto-insulated serial interface allows BMS control. Special functions per channel include relay status, channel activation, sensor failure alarm, min./max. temperature alarms, cable failure monitoring, relay test and relay cycle counter.
