118 Wiring Your I/O Modules
Features of an I/O Module
Below is an example of a combination I/O module.
Wiring Your I/O Module
Terminals on the modules have self-lifting pressure plates that accept
two 2 mm
2
(14 AWG) wires. Series B 12-point and 16-point and
analog modules are equipped with removable terminal blocks for
ease of wiring. The plug for the removable terminals is also color
coded:
• red (ac)
• blue (dc)
• orange (relay)
• green (specialty).
Status indicators on the front of each module display the status of
each I/O point. The status indicators illuminate when the proper
signal to an input terminal is applied or when the processor
commands an output to be energized.
To locate the I/O module wiring diagrams, contact your Rockwell
Automation sales office for the latest selection guide, publication
1747-SG001. Or, locate the installation instruction sheet that was sent
with your I/O module. It also includes I/O wiring diagrams.
