Overview

The ABB RK932001-AA, also known as the ZV-series communication core module, is a key component in ABB’s intelligent switchgear automation portfolio. It serves as the central logic and communication unit for UniGear ZS1, SafePlus, and UniSec medium-voltage switchgear systems. Moreover, it supports real-time control, status feedback, and secure interlocking of circuit breakers, disconnectors, and grounding switches.

This module is engineered for seamless integration with SCADA, DCS, and substation control systems. It supports industrial protocols such as Modbus and IEC 61850, ensuring compatibility with modern digital substations. Additionally, its dual mechanical-electrical interlock logic helps enforce “five prevention” safety standards, protecting both personnel and equipment from misoperation.

Technical Data

Typical Applications

• Smart Substation Automation: The RK932001-AA acts as the “nerve center” for 10–35 kV switchgear, enabling remote monitoring and control.

• Renewable Energy Integration: Used in solar and wind power step-up stations to manage high-voltage switchgear and grid connection.

• Industrial Power Distribution: Drives automation in steel, chemical, and heavy manufacturing facilities, improving reliability and safety.

• Microgrid and Distributed Energy Systems: Supports flexible interconnection and dispatch of distributed power sources.

For example, utilities in China and Europe have deployed RK932001-AA in UniGear and SafePlus switchgear to enhance operational safety and reduce manual intervention. Additionally, its wide temperature tolerance and IP54 protection make it suitable for outdoor and high-vibration environments.
