Module - digital inputs


These modules are intended for use with BMS controllers to expand their input capacity by multiplexing four or six digital signals, or 4 or 6 x 24Vac/dc inputs into a single analogue controller unit. Each combination of input states corresponds to an analogue value from the IO-DIM4 and IO-DIM6 which can be decoded into four or six digital status bits.


- Fault finding LED indication
- Auto-calibration of the output
- Input status indication
- Input status simulation
- Expands controller input capacity
