The Modbus module with 4 digital outputs was developed for decentralized switching tasks. It is suitable for switching electrical components, e.g. motors, contactors, lamps, shutters, etc. In this case, the relay contacts must be protected by suitable load-dependent measures. The module has a manual control level with which the relays can be switched manually. Via a Modbus master, the outputs can be switched via standard register. The addressing of the module, the setting of the bit rate and parity is made by 2 address switches on the front or via software. Suitable for decentralized mounting on support rail TH35 as per IEC 60715 in electric distributors. Connection with spring clamps (Push-In).This text is machine translated.
