The extension module with 8 individually configurable resistance or voltage inputs was developed for extending the range of applications of the EWIO. It is suitable for detecting resistances and voltages of, for example, passive and active temperature sensors, 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 universally configures the inputs. The module address is set by means of an address switch on the front.Suitable for direct side-by-side connection to the EWIO and mounting on DIN TH35 rail according to IEC 60715 in electrical distribution cabinets.
