Wiring guidelines
Touch Panels require regulated 12 VDC power to operate properly. The AXCESS
Central Controller supplies power via the AXlink cable. The maximum wiring
distance between the control system and Touch Panel is determined by power
consumption, supplied voltage, and the wire gauge used for the cable. Figure 13
lists wire sizes and the maximum lengths allowable between the Touch Panel and
control system. The maximum wiring lengths for using AXlink power are based on
a minimum of 13.5 volts available at the control system’s power supply.
Wiring guidelines for Touch Panel (800 mA)
