Product Name:

ABB CI854A Communication Interface Module
Part Number: 3BSE030221R1

Product Description:

The CI854A is a fieldbus communication interface module designed for use with ABB’s 800xA System (a modular, scalable automation system). It provides communication between ABB controllers (like the AC800M) and various fieldbus systems such as Profibus DP or DeviceNet. This module supports seamless integration, providing reliable and efficient data exchange between controllers and peripheral devices such as sensors, actuators, and other field devices.

The CI854A is typically used to extend the functionality of the control system by enabling communication with different automation devices, which may be operating on specific communication protocols like Profibus DP or Modbus.

Key Features:

• Fieldbus communication: Supports multiple industrial fieldbus protocols, such as Profibus DP, Modbus, or DeviceNet.
• Scalability: Suitable for use in a wide range of applications, from simple installations to complex, large-scale systems.
• Integration: Easily integrates with ABB’s 800xA control system, improving data flow and control between different system components.
• Real-time data exchange: Enables real-time data exchange between control systems and field devices for fast response times and efficient operations.
• Diagnostic capabilities: Includes diagnostic functions to ensure reliable operation and assist with troubleshooting.

Product Parameters:

• Protocol Support: Typically supports Profibus DP, Modbus, and DeviceNet fieldbus protocols (depending on configuration).
• Communication Speed: Supports various communication speeds, depending on the protocol being used (e.g., 9.6 kbps to 12 Mbps for Profibus).
• Mounting: Typically mounted in a Control Builder or I/O Terminal in the System 800xA rack.
• Redundancy: Offers redundancy options for mission-critical applications to ensure high availability.
• Power Supply: Typically powered by the control system or via a dedicated power module (depends on configuration).
• Physical Dimensions: The module’s size typically aligns with ABB’s standard module dimensions for ease of installation into control racks.

Specifications:

• Bus Protocols: Profibus DP (or Modbus/DeviceNet based on version)
• I/O Capacity: Dependent on the number of connected devices and the type of protocol in use.
• Operating Temperature Range: Typically between 0°C and 60°C (32°F to 140°F), but this can vary depending on the exact model and environmental conditions.
• Storage Temperature: Usually between -40°C and 85°C (-40°F to 185°F).
• Humidity Range: Operates effectively within 5% to 95% relative humidity (non-condensing).
• Mounting Type: Rack-mounted or DIN-rail mounting.

Product Use:

The CI854A Communication Interface Module is used in a variety of industrial automation applications, including:

1. Process Control Systems: Where integration with field devices such as sensors, actuators, and instruments is necessary for efficient monitoring and control.
2. Manufacturing Automation: In factories or production lines that require real-time communication between programmable logic controllers (PLCs) and peripheral devices.
3. Energy Management: For integrating field devices like meters and controllers in energy production and distribution systems.
4. Building Automation: In systems such as HVAC or lighting control, where various devices must communicate reliably within an automation network.
5. Oil & Gas and Chemical Industries: Where complex control systems with multiple protocols (e.g., Profibus) are common and reliable fieldbus communication is required for safety and operational efficiency.
