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.
