Chapter 3 – I/O Modules
This chapter discusses the placement and wiring for I/O modules in the
ControlWave. The chapter begins with some general instructions on
module installation and wiring guidelines that are common to most I/O
modules. The balance of the chapter includes specific details for
configuring and wiring each type of I/O module.

Installation
Installing any I/O module in the ControlWave involves the same basic
steps:
1. Remove the I/O module from the shipping carton. I/O modules
include a removable terminal housing assembly. This assembly has
a door that swings downward to provide access to the unit’s terminal
handle you can use to remove an installed I/O module once you
loosen the captured panel fasteners.
Note: Modules normally ship from the factory completely
assembled.
2. Turn the terminal block’s quarter turn fasteners (counterclockwise)
and remove the terminal housing assembly from the I/O module (see
Figure 3-1).
3. Wire the modules according to instructions for each individual
module, included later in this chapter. I/O modules support local
terminations (field wiring connected directly to the I/O module’s
terminal block PCB) or remote terminations (field wiring connected
to a remote DIN-rail mounted terminal block assembly). See Section
3.2.1 for information on local termination wiring and Section 3.2.2
for information on remote termination wiring.
4. Align the I/O module with the assigned I/O slot and gently push the
module into the chassis. When the assembly is fully seated, turn the
I/O module’s captured panel fasteners (clockwise) to secure the unit
