DPDT 24 VDC DELAY ON MAKE RELAY (JB7-R3 AND R7)
Delay on Make Operation: When
power is applied to the input
terminals (2 and 7), the time delay
starts. At the end of the preset time
delay, the output contacts
transfer. Removing input power
resets the relay.

DPDT 24 VDC DELAY ON BREAK RELAY (JB7-R4 AND R8)
Delay on Break Operation: Power is applied to the input terminals (2 and 10) at all times. When
the normally open start switch is closed, the output contacts transfer and remain in this position as
long as the start switch is kept closed. When the start switch is opened, the time delay starts. At the
end of the preset time delay, the output contacts transfer back to their original position and the relay
resets.
