Industrologic, Inc., announces the release of their UWDT485 Universal Standalone Watchdog Timer for RS-485 systems.
The UWDT485 can be used to increase the reliability of an RS-485 network by monitoring RS-485 communication, and activating a relay if the communication is no longer present.
The UWDT485 has been designed to allow easy connection to a variety of systems, and can be triggered with RS-485 communication or by an optional digital signal to monitor microcontroller based units.
The UWDT485 is based on discrete logic and relay drive circuitry and has a fail-safe design that can detect power failure as well as the absense of a trigger. On-board LEDs indicate the status of power and relay activation.
The UWDT485 can be powered by a wallblock power supply, either through a barrel type power connector or screw terminals, and can also operate from 5 volts.
The contacts of the 1 amp Form "C" relay on the UWDT485 are provided at a 3 pin screw terminal block for connection to a wide variety of failure detection circuits.
