1734-CTM | Allen-Bradley | POINT I/O Common Terminal Module

Product Description

The Allen-Bradley 1734-CTM is a POINT I/O Common Terminal Module from Rockwell Automation, designed to expand and simplify field wiring in Bulletin 1734 POINT I/O systems. This module does not provide input or output channels; instead, it offers additional terminal points that allow multiple field devices to share common connections such as power, neutral, ground, or return lines.

By offloading common wiring from I/O modules, the 1734-CTM improves cabinet organization, reduces wiring congestion, and enhances maintainability. It is typically installed alongside POINT I/O modules on a 1734-TB or 1734-TBS terminal base and is well suited for applications requiring shared field power distribution.

The module supports both AC and DC field power, making it flexible for mixed-voltage control panels commonly found in industrial automation systems.
