Revised Jun-2013 I/O Modules 3-3

ControlWave Micro I/O modules use compression-type terminals that

accommodate up to #14 AWG wire. Insert the wire’s bared end (approx.

¼” max) into the clamp beneath the screw and secure the wire. To

prevent shorts, ensure that no bare wire is exposed. If using standard

wire, tin the bare end with solder to prevent flattening and improve

conductivity. Allow some slack in the wires when making terminal

connections. Slack makes the wires more manageable and helps

minimize mechanical strain on the terminal blocks.

3.2.1 Local Termination

For I/O modules equipped with local terminal blocks, install the field

wiring between the I/O module’s removable terminal block connectors

and field devices (see Figure 3-1).

Use AWG 14 or smaller wire

(consult with the field device manufacturer for recommendations).

Leave some slack and plan for wire routing, identification, and

maintenance. Route the bundled wires out through the bottom of the I/O

module assembly between the terminal block and the terminal housing.

3.2.2 Remote Termination

For I/O modules that support remote terminations, install cables

between the module’s remote headers and the remote DIN-rail mounted

terminal block assemblies (see Figure 3-2). Install field wiring between

the DIN-rail mounted terminal bock assembly and field devices (see the

wiring diagrams associated with each I/O module description).
