Allen-Bradley 1756-IR12 - Choose Extended-Depth Housing

120 Rockwell Automation Publication 1756-UM540E-EN-P - December 2017
Chapter 6 Install ControlLogix Analog I/O Modules
Choose Extended-depth
Housing
There are two housing options available when wiring your ControlLogix analog
I/O module:
• Standard-depth housing
• Extended-depth housing
When you order an RTB for your I/O module, you receive standard-depth
housing. If your application uses heavy gauge wiring, you can order
extended-depth housing. Extended-depth housing does not come with an RTB.
IMPORTANT
The housings shown are used with a spring clamp RTB, but the capacity for
each remains the same regardless of RTB type.
