The Modbus three-point module with 6 digital inputs, 2 two-stage relay outputs and 2 digital outputs was developed for decentralized switching tasks. It is suitable for switching, for example, multi-stage pumps and fans or blinds. The relay contacts must be protected by suitable load-dependent measures. The inputs and outputs can be switched and queried using standard commands via a Modbus master. The input terminals 1 - 6 are connected to terminals C2 in a two-pole manner using potential-free switches or contacts. The module has a manual operating level for the outputs. 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 a TH35 mounting rail in accordance with IEC 60715 in electrical distribution boards. Connection with screw terminals
