Connecting Light Emitting Diodes (Leds) - Solid State Logic CapLite 64 Setup & Installation Manual

Connecting Light Emitting Diodes (LEDs).

LEDs require the current through them to be limited to 20mA or less. For a bright LED we recommend
10mA and for a dim LED we recommend 5mA.
For 10mA (Normal brightness) 12-18V use 1K, 18-24V use 2K.
For 5mA (Low brightness) 12-18V use 2K, 18-24V use 3K9.

Many of the drivers we use on our systems now have built in load sensing. This can cause LEDs to glow
dimly when they should be off. To avoid this problem, we recommend fitting a bypass resistor from the
lamp output pin to the LED supply (POS for negative outputs and vice versa). Use the same value resistor
as the for current limit resistor.

All resistors should be 1/4 Watt or higher power (e.g. 1/3 Watt, 1/2 Watt).
