The extension module in an IP65 housing with 4 digital inputs and 2 relay outputs with manual control was developed for decentralized switching tasks. It is suitable for accommodating, for example, light switches and window contacts in a room, switching two light strips or controlling louvers. It can also be used to control 2 motorized fire dampers. With strong inductive loads, we recommend protecting the relay contacts additionally with an RC element. The inputs can be used as contact or voltage inputs. The module can only be used in combination with devices from the EWIO product families (EWIO-9180 and EWIO-9180-M), which scans and switches the inputs and outputs. The module address is set by means of an address switch.
