Product Overview

The 1756-LSC8XIB8I is an Allen-Bradley ControlLogix low-speed counter input module. It provides eight individually isolated DC input channels, each configurable for standard digital input or counter functionality, with counting capability up to 40 kHz per channel. The module operates on 10 … 30 V DC via screw terminal connection, occupying a single slot in a ControlLogix chassis. Typical applications include on-machine counter capture, position monitoring, and peer-to-peer interlocks in industrial automation systems. This description applies to part number 1756-LSC8XIB8I.
