Combined input and output digital modules have circuits for both connections of input and output logic signals. They ensure galvanic isolation of inputs and outputs from the internal circuits of the PLC and filtering of faults of the input signals. The logic levels of the input and output signals are signalised by the green LED diodes on the front plate of the unit.

• connection of 8 input logic DC as well as AC signals and 8 output signals
• relays are used as switching elements
• the inputs are arranged in a set of eight with common pole
• the outputs are arranged in 2 sets of four with common pole
• galvanic isolation from PLC circuits
• the output connector is equipped by a removable screw-type or screwless terminal block
• 1 module 30mm in TC700 rack
