FS232 Watchdog relay is used to monitor the square wave signals generated by the industrial control computer (such as DC:5V or DC:24V).

When the pulse width of the measuredsignal (1ms~10s) is wider than the first preset value , the watchdog relay will output the first signal which is transmitted to control system or emergency stop switch.
