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