The LON mixed module with 4 digital inputs, 2 relays and 2 digital outputs was developed for decentralized switching tasks. It is suitable for querying switching states and then switching motors or other actuators. The relay contacts must be protected by suitable load-dependent measures. The inputs and outputs are queried or controlled by network variables SNVT. The input terminals 1 - 4 are connected to terminal C2 with two poles using potential-free switches or contacts. A wiper function is also integrated. Suitable for decentralized installation on TH35 mounting rail according to IEC 60715 in electrical distribution boards. Connection with screw terminals
