C. Latching Relays on Low-Voltage Lighting Application
Figure 7. Latching Relay Wiring Diagram.
Objective: To operate latching relays turning ON and OFF
lighting.
Suppose you want to turn ON lights at 8:00 A.M. and turn
them OFF at 5:00 P.M. each week day, using channels 3 and
4 and remote latching relay or mechanical contactor.
Suppose also that you want a “sweep” to turn OFF lights at
10:00 P.M. for any lights turned ON with the remote momen-
tary override switch (shown in the diagram above). Assume
pulse duration required for latching relay is two seconds.
NOTE: The latching relay configuration requires the use of
two channels, one to activate the latch coil, one to activate
the unlatch coil.
