3-4 I/O Modules Revised Jun-2013

Use AWG 14 or smaller wire (consult with the field device

manufacturer for recommendations) for remote terminations. Leave

some slack and plan for wire routing, identification, and maintenance.

Route the cables running between the I/O module and the DIN-rail

mounted terminal blocks out through the bottom of the I/O module

assembly via the bezel assembly.

3.2.3 Shielding and Grounding

Use twisted-pair, shielded and insulated cable for I/O signal wiring to

minimize signal errors caused by electromagnetic interference (EMI),

radio frequency interference (RFI), and transients.

When using shielded

cable, ground all shields at only one point in the appropriate system.

This prevents circulating ground current loops that can cause signal

errors.
