Output Wiring
Before connecting an output device (actuator, relay, etc.) to the controller, refer to the datasheet and installation
guide of the equipment manufacturer.
£ For a wire length less than 75’ (23m) long, either a shielded or unshielded 18AWG wire may be used.
£ For a wire length up to 200’ (61m) long, a shielded 18AWG wire is recommended.
£ The shield of the wire should be grounded on the controller side and the shield length should be kept as short
as possible.
Table 2 shows the output designation for ECx-400 UUKL I/O Extension Module.
