Isolated safety barrier/two_in and two_out switching value input, transistor output isolated safety barrier

Two-in and two-out switching value input, transistor output isolated safety barrier, receiving switch or proximity switch input from dangerous zone, transmitted to the safe zone transistor output through safety barrier isolation, each channel can be independently set to input and output in-phase or reverse phase control, and input line fault detection and alarm indication function. This product requires independent power supply.
