Isolated safety barrier/One_switch two_way switch input with LFD function isolated safety barrier

Receive the switch or proximity switch input from the hazardous area, and transmit it to the safe area transistor output through safety barrier isolation. Each channel can be independently set to input and output in-phase or reverse phase control, at the same time, it has input line fault detection alarm indication and alarm output function (LFD). This product requires independent power supply.
