Allen-Bradley 1734-CTM Programmable Logic Controller Module

The Allen-Bradley 1734-CTM is a POINT I/O Common Terminal Module that provides 24V DC field power distribution to the following POINT I/O modules on the POINTBus, consolidating field wiring around a centralized power rail for connected devices. This single-slot module in the 1734 POINT I/O family uses eight common terminals to distribute the 24V supply to adjacent I/O modules, simplifying wiring and helping ensure consistent power delivery to sensors and actuators on the bus. It is not compatible with certain terminal bases, including 1734-TB3, 1734-TB3S, 1734-TOP3, and 1734-TOP3S, per Rockwell Automation installation documentation for CTM/CTMK/VTM-series modules. Common applications include powering and wiring multiple 24V DC I/O modules in compact automation cabinets where a dedicated power-distribution point on the POINTBus is advantageous.
