FS232 Watchdog Relay
Monitors square wave signals from industrial control computers, triggering relay output when pulse width exceeds preset threshold.
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 measured signal (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.
The ultra-thin appearance design with standard 35mm rail card slot saves installation space. Combined plug-in terminals make installation and wiring easy.
| Input Signal | Square wave, DC 5V or DC 24V |
