Red Lion Watchdog Relay

Red Lion has released the Watchdog Relay, designed to monitor and provide a fail-safe shutdown of processes controlled by RTUs, PLCs and other automation devices. The industrial automation device helps to proactively protect unmanned processes on a continual basis.

The relay monitors the pulsing output heartbeat of a connected device to add an extra level of safety to protect critical processes across industrial environments that include oil, gas, maritime, power and energy. If the heartbeat stops due to a power surge, extreme weather or device malfunction, the device’s built-in Form C relay will instantly energise and provide a signal that can be used to safely shut down the process. The signal helps avoid costly damage to materials and equipment.

Built to operate in extreme conditions, the product supports temperatures ranging from -40 to 80°C, as well as 5 to 85% 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.
