Product Overview

The ABB CAI20-P is a 20-channel analog input module designed for use with CompactBlock™ LDX distributed I/O systems. It enables the accurate acquisition of analog signals from field devices such as sensors and transmitters, converting these signals into digital data for use in automation control systems. The “P” version typically denotes a current-input module (e.g., 4–20 mA) and includes enhanced protection features for industrial environments.
