6.3.5 914-AX Diagnostic LED Header
The 914-AX card includes a 10-pin header capable of driving 8 LEDs. This is useful for LED integration into an
enclosure. Each LED pin is driven low to turn on an LED, and includes a 267 ohm resistor in series to limit the
current draw. Maximum current draw is 8 mA. Refer to section 4.7 for a sample connection diagram.
The LED header is FCI P/N 20021521-00010T1LF, and the mating part is FCI P/N 20021444-00010T1LF. This can
be used with most
0.050” (1.27mm) spacing ribbon cables.
