P2 = 6-pin connector that can accommodate two 733-523 harnesses. The input harness must connect to pins 1, 2
and 3. The output harness (if used) must connect to pins 4, 5 and 6.

P2-2 and 5 = 24VDC COMMON.
l
P2-3 and 6 = Unused.
IMPORTANT:
Connector P2 MUST NOT be used for other than 24VDC, 2A power from either the Master Power
Supply or an Expansion Power Supply. If other than 24VDC, 2A power is required, input must be
made to an auxiliary relay’s center contact (see the custom label on the card’s motherboard).

24-POINT GRAPHIC I/O INTERFACE BOARD (562-789)
Features and Functions
Monitors and controls any combination of up to 24 lamp outputs and switch inputs.
l
Depending on programming, causes the lamps to turn ON continuously, flash rapidly, or flash slowly.
l
Depending on wiring and programming, the switches can be unsupervised, supervised only for opens, or
supervised for both opens and shorts.
l
Reports immediately to the Master Controller any switch status changes.
