2.4 Failsafe Alarm Relay Wiring
The “Failsafe” output relay is provided to signal critical error conditions that may occur
on the RS416. The contacts are energized upon power up of the unit and remain
energized until a critical error occurs. The proper relay connections are shown in Figure
15. A common application for this output is to signal an alarm if a power failure or
removal of control power occurs. The failsafe relay current and power handling
capabilities are specified in section 6.2 - Failsafe Relay Contact Ratings.
