The Modbus module with 4 digital outputs has been designed for decentralized switching tasks. It is suitable for switching electrical components, such as motors, contactors, lamps, blinds, etc. The relay contacts must be protected by appropriate load-dependent measures. The module features a manual control interface that allows the relays to be switched manually. Outputs can be controlled via standard registers using a Modbus master. The addressing of the module, as well as the configuration of the bitrate and parity, can be done using 2 address switches on the front or via software. It is suitable for decentralized mounting on a TH35 mounting rail according to IEC 60715 in electrical distribution boards. Connection is made with spring-loaded terminals (Push-In).
