Typical terminal designations for all products are shown below. Please confirm the
function of each pin on your device with the labeling on the circuit board prior to any
termination.

Leviton products
By default, the “IN” or the “ON” terminal is expecting +V to trigger as would be typical
with many styles of low voltage switches. If a connection to common is required, it
requires some jumper and software reconfiguration. For more information on this
topic, please see “Input Trigger-What Determines an “ON”” on page 26.
Connecting to a Low Voltage Input
Step 1: Strip each wire from your device and tightly twist the wires together.
Step 2: Insert the wires from the device into the connector on the relay cabinet
in the appropriate location.
Pin Label Function
+24V Supplies +24Vdc power to devices, usually
unregulated
COM Connection to DC Common of the cabinet
IN Switch Input or signal from device. Usually
expecting +V to trigger.
OUT Used for connection to device LED indicating on/off
state of that input. Connects to common when on,
floats when off. (Max 0.04A)
LED Used for connection to device LED indicating on/off
state of that input. Connects to common when on,
“floats” when off. (Max 0.04A)
ON Usually can be configured identically to the IN
terminal but can be configured as Momentary ON
input only
OFF Momentary OFF input only
