2.8.7.4 GFANN-I/O Module LED Wiring
There are four 12-pin connectors on the GFANN-I/O module for connecting LEDs. Each set of
10 LEDs get their power from Pin 11 of the corresponding connector. Internal resistors are
sized so that there is approximately 10 mA of current for each LED. No series resistors are
required. LED outputs are mapped to output circuits. Refer to the section titled "GFANN-I/O
LED Zone Assignments" on page 79 of this manual.
The LEDs are wired as illustrated in Figure 2.24. Note that the illustration depicts only
connectors P1 and P2. Wiring is identical for P3 (LEDs 21-30) and P4 (LEDs 31-40).
