2.4 Failsafe Relay Outputs
The “Failsafe” output relay is provided to signal critical error conditions that may occur
on the RS400 Series. The contacts are energized upon power up of the unit and remain
energized until a critical error occurs. One common application for this output is to signal
an alarm if a power failure or removal of control power occurs.
