ECB-VAV / ECB-103 Hardware Installation Guide, and (I/O) wiring methods.

 
Input Wiring:
Table 2 shows the available universal input (UIx) wiring methods.
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 the shield length should be kept as short as possible.
 
 
 
 
Output Wiring:

Table 3 shows the available output wiring methods.
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.
