About us
General
TheTBX CEP 1622 distributed input module is a monobloc module comprising 16  24 V DC inputs, compatible with 2 and 3 wire proximity sensors.
It has a terminal block for direct wiring of the sensors.
The sensor voltage is monitored to ensure that there is sufficient voltage for the inputs.
