Red Lion Watchdog Relay

Red Lion has released the Watchdog Relay, a hardware-based solution designed to monitor and provide for the fail-safe shutdown of processes controlled by RTUs, PLCs and other automation devices.

The product monitors the pulsing heartbeat output of a connected device, adding an extra level of safety that helps protect critical processes across industrial environments including 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 energise 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 product supports temperatures ranging from -40°C to 80°C as well as 5-85% humidity. It carries Class I, Div II and ATEX hazardous locations certifications, and has been marine and offshore tested or verified to meet standards such as ABS, DNV No. 2.4 and Lloyd’s.
