AutomationDirect CLICK Series User Manual

Planning the I/O Wiring Routes
The following guidelines provide general information on how to wire the I/O connections
to CLICK PLCs. For additional information about wiring a particular I/O type refer to the
corresponding information in this chapter.
1. Each terminal connection of the CLICK PLC can accept one 16AWG wire or two 18AWG
size wires. Do not exceed this recommended capacity. Refer to Chapter 2 Specifications for
more detailed specifications of the terminal blocks.
2. Always use a continuous length of wire. Do not splice wires to attain a needed length.
3. Use the shortest possible wire length.
4. Use wire trays for routing where possible.
5. Avoid running lower voltage wires near higher voltage wiring.
6. Avoid running input wiring close to output wiring where possible.
7. To minimize voltage drops when wires must run a long distance, consider using multiple
wires for the return line.
8. Avoid running DC wiring in close proximity to AC wiring where possible.
9. Avoid creating sharp bends in the wires.
10. Install the recommended powerline filter to reduce power surges and EMI/RFI noise.
