Watchdog timer relay circuits.

The connections are labeled wd com watchdog common wd no watchdog normally open and wd nc watchdog normally closed. 40 to 125 c packages. Newer designs of time delay relays use electronic circuits with resistor capacitor rc networks to generate a time delay then energize a normal instantaneous electromechanical relay coil with the electronic circuit s output. During normal operation the computer regularly resets the watchdog timer to prevent it from elapsing or timing out.

Available watchdog timeout periods are 3 4 ms 6 3 ms 102 ms and 1 6 s chip enable input open drain or push pull wdo output operating temperature range. 1 0 out of 5 stars 1. Watchdog timer brentek p8 wdt24 plc iso opto isolated input 2 sec. Press the bypass button to enable bypass mode.

Apply power to the watchdog relay power input and the form c relay that will power the plc instruments. This will power up the watchdog relay and the plc instruments but since no heartbeat pulse is configured the form c relay will be deactivated after the boot delay time expires. This relay is intended to be used in safety interlock circuits used in a system operated by an acr controller card. If due to a hardware fault or program error the computer fails to reset the.

Watchdog timer circuit datasheet production data the stwd100 watchdog timer has an input features current consumption 13 µa typ. The electronic timer relays are more versatile than the older mechanical models and less prone to failure.
