ABB FI810F 3BDH000030R1 AC 800F CAN Fieldbus Module

ABB FI810F 3BDH000030R1 AC 800F CAN Fieldbus Module

The ABB FI810F 3BDH000030R1, also cataloged as the FI810F Fieldbus Communication Module, operates as a dedicated hardware component for multi-channel CAN bus interfacing within ABB AC 800F / Freelance DCS platforms. The unit executes direct data communication across three independent, galvanically isolated CAN interfaces conforming to ISO 11898 and CAN 2.0B standards. Each port processes deterministic signals up to 1 Mbps, establishing physical link connectivity between field devices and central rack controllers. Diagnostic light-emitting diodes provide real-time visual verification of port activity and module system health.

Hardware Specifications

Backplane Bus Communication & I/O Density Scaling

The module mounts directly into the AC 800F rack system, interfacing with the internal backplane bus to deliver high-velocity data transfer to the main processor. Integrating three independent physical channels on a single assembly maximizes rack-level I/O density scaling without demanding additional backplane slot allocation. Electrical isolation rated between 2000 VDC and 2500 VDC mitigates common-mode ground loop current and suppresses industrial electromagnetic transients. Active firmware flash compatibility ensures seamless driver integration across standard Freelance engineering station software builds.

Frequently Asked Questions

Q: What isolation voltage does the FI810F provide between independent CAN channels and the internal rack system?

A: The module maintains continuous galvanic isolation between 2000 VDC and 2500 VDC, separating individual CAN ports from each other, from the controller system backplane, and from protective earth ground.

Q: Can the CAN interfaces operate at different baud rates simultaneously?

A: Yes, each of the three CAN channels operates independently, allowing configuration of distinct data rates up to 1 Mbps and different application protocols per channel.

Field Installation Guidelines

First, turn off all power to the target AC 800F rack before inserting or removing the module. Align the guide rails of the card with the assigned rack slot and push the assembly firmly until the rear connector seats into the backplane bus. Fasten all retaining screws to establish chassis ground continuity and prevent vibration-induced loosening. Route CAN trunk lines using shielded twisted-pair cables with 120 ohm characteristic impedance. Ground cable shields at a single point near the rack entry to prevent circulating ground currents. Terminate both physical ends of each CAN bus network segment with standard 120 ohm resistor terminations across CAN_L and CAN_H signal lines. Maintain a minimum clearance of 50 mm above and below the module enclosure to allow adequate convective airflow and preserve operating thermal profiles below +70 deg C.
