DDACM - MODBUS RTU IO MODULE

The DDACM series are intended for converting Modbus RTU (RS485) data into analogue / modulating output signal (0—10 VDC / 0—20 mA / PWM). They feature 3 outputs and are Power over Modbus supplied and all parameters are accessible via Modbus RTU. The series needs a master unit, such as the Sentera RDPU or any BMS or master module that is able to write a value in Modbus Holding registers. The converters can control devices with voltage, current or PWM inputs , e.g. an EC fan.
