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.
£
For relay outputs (DOx); select appropriately-sized wiring suitable to the current load.
£
To measure the state of a triac output, an external load must be connected.
Table 3 shows the ECL-203, ECL-300, ECL-400, and ECL-600 Series controller Output and Jumper support. Table 4 shows the available output wiring
methods.
