ABB CI820V1

1. Key Functional Characteristics

Primary Role: Acts as a communication interface between the AC 800M controller and S800 remote I/O systems, facilitating high-speed data exchange and control in distributed automation systems .

Communication Protocols: Supports key industrial protocols including Profibus DP and Modbus .

Redundancy: Designed to support redundant configurations, often paired with redundant CPU modules to ensure high system availability and fault tolerance .

Hot-Swap Capability: A crucial feature for maintenance, allowing the module to be replaced without shutting down the entire control system, thereby minimizing downtime .

Connection Method: Utilizes fiber optic links for data transmission to remote I/O, offering advantages in noise immunity, data security, and longer transmission distances .

2. Mechanical Specifications

Dimensions: 132mm (H) × 105mm (W) × 52mm (D) .

Weight: 800 grams .

Housing: Constructed with a ribbed aluminum casing for enhanced strength and heat dissipation .

Protection Rating: IP30 , indicating it is protected against solid objects larger than 2.5mm but not against moisture. Other sources mention a higher IP65 rating , which would indicate complete dust ingress protection and protection against low-pressure water jets. The application environment should be checked against the specific rating required.

Installation: Mounts on a standard 35mm DIN rail .

3. Electrical and Environmental Specifications

Operating Voltage: Commonly listed as 24V DC . One source also mentions 220V AC , which may refer to a different variant or system power requirements.

Operating Temperature Range: A standard range of -20°C to +70°C . A wider range of -40°C to +85°C is available as an option for harsher environments .

Relative Humidity: Up to 90% (non-condensing) .

Storage Temperature: -40°C to 80°C .

4. Performance and Certifications

EMC Compliance: The module has undergone rigorous testing and complies with multiple IEC standards for electromagnetic compatibility, including:

IEC 61000-4-2 (ESD Immunity): ±8 kV (air), ±4 kV (contact) .

IEC 61000-4-4 (EFT/B Immunity): ±2 kV on power lines, ±1 kV on data lines .

IEC 61000-4-5 (Surge Immunity): ±1 kV (line-to-line), ±2 kV (line-to-earth) on power lines .

IEC 61000-4-6 (Conducted Immunity): 10 V .

Other Certifications: CE Marking, UL, RoHS .

5. Application Scenarios

The CI820V1 is engineered for high-reliability applications in critical industrial sectors:

Power Generation: Used in (substation automation control systems) .

Oil & Gas: Employed in (refinery process control) due to its ability to handle harsh environments .

Water/Wastewater Treatment: Applied in (monitoring systems) for real-time control .

Manufacturing & Process Industries: Suitable for steel, pulp & paper, and other industries requiring robust, distributed I/O and control .

6. Additional Information

Software Integration: Configured and integrated using ABB's engineering tools like Control Builder .

System Compatibility: Designed for seamless integration into the ABB 800xA extended automation system architecture with AC 800M controllers and S800 I/O
