10.4" Touch Panels
The maximum wiring lengths for using AXlink power are based on a minimum of 13.5 VDC
available at the Central Controller's power supply. Refer to the Specifications section on page 1 for
more information on power requirements.
If you install the touch panel farther away from the control system than recommended in the Wiring
Guidelines table, connect an external 12 VDC power supply to the 2-pin PWR connector on the
touch panel.
Using the PSN connector for power
To use the 2-pin mini-Phoenix power supply jack for power transfer from the PSN power supply,
the incoming PWR and GND cable from the PSN must be connected to the corresponding location
on the 2-pin AXlink connector (FIG. 6).
1.
Insert the PWR and GND wires into the terminal end of the PSN 2-pin AXlink cable.
2.
Tighten the clamp to secure the two wires.
3.
Verify the connection of the other end to the 2-pin 3.5 mm mini-Phoenix on the PSN.
Using AXlink for data and power
Connect the Central Controller's AXlink connector to the AXlink connector on the touch panel for
data and 12 VDC power as shown in FIG. 7.
