Allen-Bradley 20-750-1132C-2R PowerFlex 750 Variable Frequency Drive

The Allen-Bradley PowerFlex 750 20-750-1132C-2R is a 24V DC I/O option module for the PowerFlex 750 drive family that adds a compact, on-drive I/O interface to support basic sensing and signaling tasks. It provides one analog input (AI), one analog output (AO), three digital inputs (DI), and two relay outputs (RO), all powered from a 24V DC supply. This module is designed to mount with PF750 drives and connect via the drive’s I/O bus, enabling straightforward wiring of field devices such as sensors, limit switches, and actuators without the need for a separate PLC for these signals. Typical applications include simple machine-control tasks on conveyors, packaging lines, and pump/fan systems where a small set of local, 24V I/O is sufficient for start/stop control, status indication, alarms, and basic analog signal feedback. The 20-750-1132C-2R designation identifies the PF750 24V I/O Module variant with the described I/O counts, making it a common choice for retrofit or expansion in existing PF750 installations. In practice, this module lets you extend the PF750’s automation capabilities by providing ready-to-wire input and output points that stay within the Rockwell Automation PowerFlex ecosystem, preserving compatibility and simplifying panel wiring.
