UWDT485 OEM Universal Watchdog Timer
The Industrologic UWDT485 is a versatile standalone watchdog timer circuit that can increase the reliability of nearly any RS-485 network, by monitoring communication on the network, and activating a relay if communication is no longer present.
It can also be used to increase the reliability of numerous microcontroller systems by monitoring a digital output signal.
The UWDT485 has been designed to allow easy installation alongside an RS-485 network, and includes operation that makes the relay operate in a fail-safe mode.
