Product Overview

The CP1W-MAB221 adds essential analog capability to CP-series controllers when machine applications require variable measurement and command outputs. It is useful for integrating pressure, flow, level, or speed references without moving to a larger PLC platform. With two analog inputs and one analog output, the module supports practical feedback-control loops, setpoint transmission, and process tuning for OEM machines that combine discrete sequencing with analog regulation.

FAQ for CP1W-MAB221

What does the 2AI/1AO configuration enable?
It enables reading two process variables while outputting one control command, useful for compact closed-loop regulation.
Is CP1W-MAB221 only for process plants?
No. It is often used in machine automation where limited analog sensing and one analog command output are needed.
Why add this module instead of changing PLC family?
It provides needed analog functionality while preserving existing CP-series architecture, software, and spare-parts continuity.
