The extension module with 4 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 operated by means of potential-free switches or contacts or used as 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.
