•
Pins #3 and #4 are the output of an electrical relay. The relay contacts are rated at 250VAC / 6
AMPS.
•
The relay contacts are in a NORMALY OPEN state (when the LED is not emitting light).
•
When the LED is emitting light, the relay contact will “CLOSE” and will have electrical continuity
through pin# 3 and #4.
•
You can connect a series load of up to 250VAC / 6 AMPS.
•
So the relay contact is “OPEN”, when no light is present. And “CLOSED” when light is present. (It’s
a simple SINGLE POLE SINGLE THROW SWITCH).
