ABB CBI20 Binary Input Module – Product Description

Overview

The ABB CBI20 is a robust 32-channel binary input module designed for Symphony Plus and Advant control systems. It acquires digital signals from field switches, pushbuttons, and NAMUR sensors, then transfers them reliably to the controller for precise process automation. Moreover, its versatile input handling allows engineers to consolidate various signal types into one unified module.

The module integrates transmitter power supply functionality, therefore simplifying wiring and reducing panel complexity. In addition, each channel maintains stable performance in demanding installations where electrical noise, vibration, or temperature shifts may affect signal integrity. Plants relying on high-availability control systems often select the CBI20 because it delivers consistent and predictable input acquisition.
