Red Lion Controls has unveiled the Watchdog Relay, the industry’s only rugged, hardware-based solution that reliably monitors and provides fail-safe shutdown of processes controlled by RTUs, PLCs and other automation devices.

As an industrial automation solution, the new device helps to proactively protect unmanned processes on a 24/7 basis.

Red Lion’s Watchdog Relay monitors the pulsing output heartbeat of a connected device to add an extra level of safety that helps protect critical processes across industrial environments that include oil, gas, maritime, power and energy. If the heartbeat stops for reasons that may include power surges, extreme weather or device malfunctions, Watchdog’s built-in Form C relay will immediately energize and provide a signal that can be used to safely shut down the process. The signal sent upon loss of control helps to avoid costly damage to materials and equipment.

Built to operate in extreme conditions, the Watchdog Relay supports temperatures ranging from -40ºC to 80ºC, as well as 5 to 85 percent humidity. It carries Class I, Div II and ATEX hazardous locations certifications, and has been marine and offshore tested and/or verified to meet standards such as ABS, DNV No. 2.4 and Lloyds.

“Customers need back-up safety measures to make sure that if equipment fails, it does so safely,” said Jacob Colegrove, product manager at Red Lion Controls. “Watchdog Relay is a rugged, hardware-based solution, and since there is no software to lock up or fail, it gives an extra level of safety to networks and processes. This is important for environments with valves, pipelines, heavy machinery or other critical items.”
