Technical/electrical characteristics of the inputs and outputs.
7.7.1
Digital inputs.
All digital inputs are galvanically isolated up to 500 V through opto-couplers. All digital inputs
meet the standard IEC61131-2 type 1 and type 3.
7.7.2
Digital outputs.
All digital outputs are galvanically isolated up to 500 V through opto-couplers. All the digital
outputs have the following characteristics:
