Overview

The ABB CBC 11 is a binary control module engineered for use within the Symphony Harmony Rack (HR) Series. It combines multiple functions—power output switching, sensor supply, and binary input interrogation—into a single compact unit. This integration simplifies system architecture and reduces wiring complexity.

Moreover, the CBC 11 supports both P-switching and N-switching outputs, each capable of delivering up to 100 mA with short-circuit protection. In addition, its sensor supply outputs provide 24 V or 36 V options, making it compatible with a wide range of field devices. The module also features diagnostics and modular redundancy, enhancing fault tolerance and system reliability.

Therefore, it’s widely used in power generation, process automation, and infrastructure control systems where robust binary control is essential.

Technical Data

Typical Applications

Power Plants

Controls auxiliary systems such as pumps, fans, and switchgear.

Process Automation

Interfaces with sensors and actuators in chemical and manufacturing plants.

Infrastructure Systems

Used in water treatment, HVAC, and transportation control panels.

OEM Control Panels

Embedded in custom automation solutions requiring binary control and diagnostics.

In high-reliability environments, operators benefit from the short-circuit protection and modular redundancy, which reduce downtime and improve fault isolation. Additionally, its support for proximity switches expands its use in modern sensor networks.
