Allen-Bradley 1756SC-CTR8
8-Channel Counter / Flowmeter Input Module for ControlLogix® Systems
Product Description
The 1756SC-CTR8 is an 8-channel counter/flowmeter input module designed for use in ControlLogix® systems. Manufactured by Spectrum Controls in collaboration with Rockwell Automation, this module provides high-speed counting and flow measurement capabilities for industrial automation applications. It supports incremental, up/down, and quadrature counting modes, and is ideal for turbine flowmeter integration, encoder feedback, and general-purpose event counting. Each channel operates independently and supports simultaneous rate and count measurement.
