Allen-Bradley 1746-OV32 SLC 500 Output Module

The Allen-Bradley 1746-OV32 is a 32-point output module for the SLC 500 programmable logic controller family. As an output module, it accepts switched logic signals from the PLC CPU and provides 32 discrete outputs that can be used to control external devices in automation schemes. The 1746-OV32 is designed to plug into an SLC 500 I/O backplane, expanding the controller’s capability within a single chassis by adding 32 output points. This module is typically used to drive actuators and other field devices under PLC control, enabling centralized sequencing and automation across manufacturing, packaging, and process lines. Typical installation involves wiring external field devices to the module’s outputs and routing status or fault indicators to the controller as part of the broader SLC 500 I/O network. The model number 1746-OV32 identifies a specific discrete-output option within the Allen-Bradley 1746 series, ensuring compatibility with the SLC 500 ecosystem when paired with appropriate chassis, power, and communication modules. Its 32-point configuration makes it a common choice when project requirements require increased I/O density without upgrading the main controller.
