METZ CONNECT 1108331326 MR-DIO4/2 RTU Modbus

MR-DIO4/2 Modbus RTU, The Modbus module with 4 digital inputs and 2 relay outputs with manual control level was developed for decentralized switching tasks. Suitable for e.g. incorporating light switches and window contacts in a room and switching 2 light strips or as a blind control. 2 motor-operated fire dampers can also be controlled. The relay contacts must be protected by suitable load-dependent measures. The inputs can be operated as contact or voltage inputs. The inputs and outputs can be switched and queried via standard registers using a Modbus master. The module address, bit rate and parity are set using 2 switches on the front or via software. Suitable for decentralized installation in the series sub-distribution board. Connection with screw terminals
