The Digital Input Output Module is used for connecting of up to 16 intrinsically safe digital signals to the IS1 Remote I/O system. All channels can be parameterised in pairs as input for connection of passive contacts or NAMUR proximity switches (EN 60947-5-6) or as output for connection of low power solenoid valves. Up to 8 inputs can be used as frequency inputs or counters up to 20 kHz, in operating mode "Rotation direction recognition" and "Forward/backward counter" up to 4 inputs. The Ex i inputs or outputs are short-circuit proof and galvanically separated from the system.
