DEVIreg™ Multi is 7 channel electronic programmable controller to be installed on DIN rail. Every channel can be individually set up with three control modes – with temperature sensor, time proportional power regulation without sensor and manually on/off with time limitation. Сhannels inputs can be selected via software between 8 types of temperature sensors including NTC 15 kOhm at 25°C. Modbus RS485 opto-insulated serial interface gives possibility for BMS control. DEVIreg™ Multi has some special functions which can be programmed for every channel: relay status - opened or closed correspondently to ‘Heating On’ mode, channel activation or deactivation, sensor failure alarm, min and max temperatures alarm, cable failure monitoring, relay test, channel on/off, relay cycles calculator, etc
