The IB-7302 binary input module has 32 binary inputs, 24 VDC, common pole, type 1. The inputs are in groups of 16, which are galvanically isolated from each other. The module is galvanically isolated from the other PLC circuits. The module input circuits require 24 VDC power supply (the positive pole of power supply to the UDIx terminals, the negative pole to the COMx terminals).
