Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 1756-PLS is an Allen-Bradley ControlLogix Programmable Limit Switch Module, designed to interface resolver-type position feedback devices to a ControlLogix backplane. It accepts a resolver input, converts it to digital counts, and provides configurable digital outputs suitable for position-based control logic. The module integrates into ControlLogix racks and is used in industrial automation systems for sequencing, motion tracking, and positional limit enforcement. Part number 1756-PLS is fully discontinuing December 31 2025, with repair possible until then. 1756-PLS is intended for applications requiring limited-axis position detection and logic output generation.
