PIN Name Description
1 Intensity Input
Input voltage is converted to required current to achieve desired intensity;
intensity will vary linearly between 20% and 100% for voltages between 1V
and 5V respectively.
A minimum voltage of 0.4V is required for proper light source operation. If
the user inputs a voltage
below the minimum required, the light source will
not turn on.
2 Enable High
0.0V to +0.6V = Turns LEDs off (Open input will default to OFF).
+2.4V to +24.0V = ON.
3 Enable Low
0.0V to +0.6V = Turns LEDs on.
+2.4V to +24.0V = Turns LEDs off (Open input will default to OFF).
4 Thermal Fault
0.0V to +0.4V (ground) = Fault
+2.4V to +5.0V (open) = No Fault
5 IsoDGND Ground Reference for digital IOs
6 IsoVCC +5.0V Output.
7 Reserved Do not connect
8 Door Lock *
0.0V to +0.6V = UV Emission Allowed.
+2.4V to +24V = UV Emission Stopped.
9 IsoGND Ground Reference for analog IOs.
10 LED ON
0.0V to +0.4V (ground) = LED off
+2.4V to +5.0V (open) = LED on.
11 Reserved Do not connect
12 UV LED Fault
0.0V to +0.4V (ground) = Fault
+2.4V to +5.0V (open) = No Fault
13 Reserved Do not connect
