The extension module with 10 digital inputs was developed for decentralized switching tasks. It is suitable for detecting potential-free switch states, for example electrical limit switches on vent valves or auxiliary contacts of power contactors. The inputs can be used as contact or voltage inputs. The extension module can only be used in combination with devices from the EWIO product families (EWIO-9180 and EWIO-9180-M), which scans the outputs. The module address is set by means of an address switch on the front.Suitable for decentralized mounting in serial sub-distributor.
