The 1771-CFM is a configurable flow meter module manufactured by Allen-Bradley (part of Rockwell Automation) for its PLC-5 Programmable logic controller (PLC) system used in industrial automation. Here is a breakdown of its functions and key features:
Features:
The 1771-CFM can be connected to a variety of flow sensors, such as magnetic pickups, single-channel shaft encoders and turbine flowmeters.
It converts the pulses received from these sensors into a digital format that the PLC can understand and process.
This enables the PLC to measure flow, control pumps and valves based on flow readings, and integrate flow data into automated processes.
