Output Tables
Protection from faults and control power loss.
Normally Energized Models
Normally De-Energized Models
Latching (Mechanical Relay Output) Models
Latching models power up
initially in the rest (normal)
mode. If there is a fault
condition or the test button is
pushed, the output contacts
will change state and latch.
The output will remain
latched regardless of whether
the fault is cleared or control
power is removed. To reset
the output, apply a
momentary contact across
“reset” terminals.
