Allen-Bradley 1756-CFM ControlLogix Configurable Flowmeter Module 2-Channel
Product Overview
The Allen-Bradley 1756-CFM is a high-precision, dual-channel configurable flowmeter module designed for the ControlLogix® platform. It provides a direct interface between turbine flowmeters and the Logix controller, eliminating the need for external signal transmitters or secondary pulse counters. This module is specifically engineered to handle frequency-based signals, converting them into meaningful flow and accumulation data for complex process control.
Supporting both Totalizer and Prover operational modes, the 1756-CFM is a versatile solution for custody transfer, blending, and dispensing applications. It features two independent flowmeter inputs along with two dedicated gate inputs, allowing for high-speed gating and precise fill-to-target operations. With its 32-bit counter resolution and integrated noise filtering, it ensures accuracy even in electrically noisy industrial environments.
