Input Wiring
Before connecting a sensor to the controller, refer to the installation guide of the equipment manufacturer.
£ For a wire length less than 75’ (23m), either a shielded or unshielded 18AWG wire may be used.
£ For a wire up to 200’ (61m) long, a shielded 18AWG wire is recommended.
£ The shield of the wire should be grounded on the controller side only and shield length should be kept as short as possible.
Table 2 shows the available universal input (UIx) wiring methods
