UWDTIE Reference Manual
UWDTPC, Universal Standalone Watchdog Timer - $25
Isolated Trigger Input/E-Stop OEM Version
The Industrologic UWDTIE is a standalone watchdog timer circuit that can be
used to increase the reliability of nearly any PLC, industrial microcontroller
board, or industrial single board computer by monitoring a digital output
signal and activating a relay circuit if the signal is no longer present.
The UWDTIE has been designed to allow easy connection to a variety of systems,
and can be triggered with switched voltages or logic level signals.
- Based on discrete logic and relay drive circuitry
- Opto-isolated digital trigger input
- Fail-safe operation optimized for E-Stop circuitry
- Screw terminal block connections for power, relay, and digital trigger signals
- 10 amp Form "C" relay with connections to all contacts
- LED indicators for power and relay activation
- On-board power supply for all circuitry
- Pin-type power connector for easy connection to wall block power supplies
The UWDTIE is not a single piece "Stock Product", but is available in small quantities on a limited basis with the expectation that the user may specify the optoisolator current limiting resistor and trigger timing when purchasing a large quantity after the evaluation.
