Allen-Bradley 505-BOD Programmable Logic Controller IO Module

The Allen-Bradley 505-BOD is a NEMA Size 1 reversing motor starter from Rockwell Automation, designed for compact, reliable forward/reverse control of small AC motors in industrial panels. It is configured for a 120 V AC coil and offered in an open enclosure footprint, combining two contactors with interlock logic to swap the motor’s line connections for reversing direction. This 505-BOD assembly is used as a standalone motor control device that integrates with external pushbuttons, relays, or timers to provide start/stop sequencing and reversible operation within a small footprint. Variants in the 505-BOD family include submodels such as 505-BOD-A2C and 505-BOD-A2G (and related configurations like 505-BOD-17-23), which reflect different accessory options while preserving the core reversing function. Typical applications include small conveyors, machine tools, and general machinery where a rugged, space-efficient reversing starter is preferred over a full motor controller, and where an open-type package is suitable for panel mounting. This product is a motor starter, not a programmable logic controller I/O module, and is intended for use in traditional control circuits that drive a reversing arrangement rather than direct PLC I/O.
