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 1 shows the ECL-203, ECL-300, ECL-400, and ECL-600 Series controller pulse and current input jumper support. Table 2 shows the available uni-
versal input (UIx) wiring methods.
