The extension module with 4 analog outputs was developed for decentralized switching tasks. It is suitable as encoder for control variables, for example for electrical vent and mixing valves, valve positions, etc.The extension module can only be used in combination with devices from the EWIO product families (EWIO-9180 and EWIO-9180-M), which switches the outputs. The module address is set by means of an address switch on the front.Suitable for decentralized mounting in serial sub-distributor.
