Allen Bradley 1756-LSC8XIB8I ControlLogix Low-speed Counter Module

Product Introduction

The Allen Bradley 1756-LSC8XIB8I ControlLogix Low-speed Counter Module is a dedicated counting and event detection module designed for integration within the ControlLogix automation platform. It is engineered to process low-frequency pulse signals with high reliability, making it suitable for industrial applications where accurate counting and signal isolation are essential.

Equipped with 8 individually isolated inputs, this module ensures channel-to-channel electrical separation, minimizing cross-talk and improving overall system stability. The 10–30 V DC input range allows compatibility with a wide variety of industrial sensors, including proximity switches, photoelectric sensors, and flow transmitters with pulse outputs.

The module also features a peer-to-peer input interface via a 36-pin connector, enabling direct communication between compatible modules. This reduces controller scan dependency and enhances responsiveness in distributed or coordinated automation systems.

Designed for installation in a standard 1756 ControlLogix chassis, the 1756-LSC8XIB8I offers reliable performance in industrial control panels operating within standard temperature ranges.
