MR-DIO4/2
The Modbus module 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 with an RC element. The inputs can be used as contact or voltage inputs. The inputs and outputs can be switched and scanned by means of standard objects via a Modbus master. The module address, the baud rate and the parity are set by means of two address switches on the front. Suitable for decentralized mounting in serial sub-distributor.
