Key Features & Benefits

Intelligent Voltage Monitoring: The CP-A CM continuously monitors both input channels of the CP-A RU redundancy unit, detecting undervoltage conditions with precision. Adjustable voltage thresholds (14-28V DC) allow customization for diverse power supply configurations.

Automatic Failover Protection: When an input channel drops below the configured threshold, the module triggers immediate switchover to the backup power source, preventing system downtime and protecting sensitive automation equipment.

Visual Status Indication: Integrated LED indicators provide instant visual feedback on power channel status, simplifying troubleshooting and system health monitoring during commissioning and maintenance.

Application Scenarios

The CP-A CM control module is essential for high-availability industrial applications requiring uninterrupted power:

• Process Control Systems: Chemical plants, refineries, and pharmaceutical manufacturing where power interruptions could compromise product quality or safety
• Critical Infrastructure: Water treatment facilities, power substations, and telecommunications hubs demanding 24/7 operation
• Manufacturing Automation: Automotive assembly lines, semiconductor fabrication, and food processing requiring continuous production
• Building Management: Data centers, hospitals, and commercial facilities with mission-critical HVAC and security systems
• Transportation Systems: Railway signaling, airport ground control, and traffic management infrastructure

System Integration Solutions

The CP-A CM is designed to work seamlessly with ABB's CP-A redundancy ecosystem. For complete redundant power architecture, pair with the ABB CP-A RU Redundancy Unit (1SVR427071R0000) as the primary switching module. Power your system with the ABB CP-C 24/20.0 Power Supply (1SVR427026R0000) for reliable 24VDC output, or upgrade to the ABB CP-E 24/20.0 Power Supply (1SVR427036R0000) for enhanced efficiency and wider input voltage range.

Installation & Configuration

The CP-A CM mounts directly onto standard 35mm DIN rail alongside the CP-A RU unit. Connection is simplified through plug-in terminals requiring no special tools. Voltage threshold adjustment is performed via precision potentiometer, allowing fine-tuning to match your specific power supply characteristics. Detailed wiring diagrams and configuration procedures are included in the technical documentation.

Frequently Asked Questions

Q: Can the CP-A CM operate independently without a CP-A RU unit?
A: No, the CP-A CM is specifically designed as an accessory module for the CP-A RU redundancy unit. It enhances the RU's monitoring capabilities but requires the RU for switching functionality.

Q: What happens if both input channels fail simultaneously?
A: The CP-A CM will detect both undervoltage conditions and signal the fault. However, redundancy protection requires at least one healthy input channel. For complete protection, ensure diverse power sources feed each input.

Q: Is the voltage threshold adjustment accessible during operation?
A: Yes, the threshold potentiometer is accessible on the module front panel. However, we recommend adjusting thresholds during commissioning or scheduled maintenance to avoid unintended switching events.

Q: Does this module support hot-swapping?
A: While the module can be physically removed during operation, we recommend de-energizing the system before installation or removal to prevent potential switching transients.
