MR-DIO4/2-IP65 Modbus RTU, The Modbus module in an IP65 housing with 4 digital inputs and 2 relay outputs was developed for decentralized switching tasks. Suitable for e.g. accommodating light switches and window contacts in a room and switching two 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 two switches or via software.
