Allen-Bradley 1756-PLS | Programmable Limit Switch | Resolver

Allen-Bradley 1756-PLS | ControlLogix Programmable Limit Switch – Resolver Interface, 4x4 I/O, 3-Slot Module

Overview

The Allen-Bradley 1756-PLS is a high-speed programmable limit switch (PLS) module for the ControlLogix platform, designed for motion control and precision timing applications. This 3-slot wide module features a resolver interface and 4 groups of 4 configurable inputs and outputs, providing real-time response based on position feedback.

Ideal for rotary indexing, high-speed packaging, labeling, or press operations, the 1756-PLS enables tight synchronization between machine motion and discrete outputs with microsecond-level accuracy.
