CI920AN S900 Communication Module ABB 3BDH000692R1 | Redundant

Product Overview

• The CI920AN (3BDH000692R1) is a high-speed communication interface for the ABB S900 I/O system.
• It serves as the gateway between the internal CAN bus of the I/O station and the external PROFIBUS DP-V1 network.
• Classified as Type N, this module is optimized for installation in safe, non-hazardous industrial areas.
• The CI920AN supports advanced features like HART over PROFIBUS and full media redundancy.

Typical Application Scenarios

• Central communication hub for remote S900 I/O clusters in industrial safe zones.
• Redundant network architectures for high-availability chemical or power generation plants.
• Asset management systems requiring HART data extraction from 4...20mA loops.
• Modernization projects aimed at reducing marshalling costs by placing I/O stations closer to the process.

Global PLC Spare HUB’s Insight

• The CI920AN is a critical component for ensuring deterministic PROFIBUS communication.
• Our engineers recommend this "Type N" version for cabinet-based installations where hazardous gas is not a factor but reliability is paramount.
• The S900 I/O system's "error-tolerant" design ensures that a single module failure does not compromise the entire fieldbus link.

Shipping & Warranty Terms

• Warranty: 12-month professional quality guarantee on all CI920AN units.
• Express Logistics: Fast worldwide delivery via DHL, FedEx, and UPS.
• Handling Time: Dispatched from stock within 24 to 48 hours.
• Compliance: CE marked, RoHS compliant, and WEEE certified.

Expert FAQ & Selection Tips

• Can I use CI920AN in a Zone 2 area?
• No, the CI920AN is Type N (Safe Area only). For Zone 2, you must use the CI920AB (Type B) or CI920AS (Type S).
• How do I configure redundancy for this module?
• Two CI920AN modules must be installed in the dedicated redundancy slots of the S900 rack.
• Does it support HART over PROFIBUS?
• Yes, it fully supports HART acyclic data, allowing you to access secondary variables of your field instruments.
• What is the maximum cable length for the PROFIBUS connection?
• This depends on your baud rate; at 1.5 Mbps, the standard segment length is 200m without repeaters.
• Is the firmware field-upgradable?
• Firmware can be managed via the SICK CDS or ABB engineering tools, but ensure matched versions for redundant pairs.
