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, blinds, etc. 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. The outputs can be switched via standard registers using a Modbus master. The module is addressed and the bit rate and parity are set using two address switches on the front or via software. Suitable for decentralized installation on TH35 mounting rails in accordance with IEC 60715 in electrical distribution boards.
