Rugged Hardware-Based Solution for Fail-Safe Shutdown
Red Lion’s Watchdog Relay is 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.
By monitoring the pulsing output heartbeat of a connected device, Watchdog Relay adds an extra level of safety
that helps protect critical processes. 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.
