Can a WLEDL-150 Be Turned on by an external contact?


The telemetry input can be used to control the lamp and dim function from an external source.


  • WLEDL-150


  • Remote Operation.


By default, the telemetry inputs are wired together (CLOSED) for standard photocell controlled on/off operation. If required to be activated by an external source, connect as an appropriate volt-free or TTL input source using a dry contact.

Volt free input/dry contact:
TTL input

Non polarity sensitive:
Orange = TTL +, Purple = TTL (GND)
0V = Light on, 3V = Light off

Short circuit = light on
