Features:
- CI820V1 3BSE025255R1 is the complete listed product identity for the supplied hardware execution.
- The documented hardware is an ABB communication interface unit selected for its assigned equipment role.
- Installation requires a verified match to Advant S800 I/O, the connected assemblies and the approved configuration.
CI820V1 3BSE025255R1 is an ABB communication interface unit selected by its complete product identity and documented equipment role. Its suitability depends on the installed Advant S800 I/O system, hardware execution, interfaces and application requirements matching the supplied unit. Visual similarity or a shortened code is not proof of interchangeability.
Before replacing CI820V1 3BSE025255R1, record the full nameplate, installed position, connector or terminal arrangement, paired equipment and relevant ABB service information. After installation, verify power, communication and control interfaces, complete the approved functional checks and confirm stable operation before returning the equipment to service.
The CI820V1 3BSE025255R1 ABB Communication interface unit is supplied subject to exact-item verification. Current revision, lifecycle status, availability and supplied scope are confirmed in the written quotation.

Important Notice: Every linked document must identify the listed model or its documented family. Confirm the complete order code, hardware revision and installed-system requirements before replacement.
The CI820V1 is a plug-in processor module that requires a compatible electrical backplane to connect terminal cables:
Certified Maximum Transmission Unit (MTU): Must be plugged into a TU846 or TU847 module terminal unit. Mechanical error protection: Employs factory hardware error protection code "AA" to prevent accidental mis-insertion with other network interface cards.
Electrical isolation: Standard embedded safety shielding layer with a rated voltage up to 500 V RMS shields against voltage differences between the backplane and field cabling circuitry.
The CI820V1 prioritizes uninterrupted network data transmission, making it widely used in large-scale industrial applications with extremely high uptime requirements:
Distributed Control Systems (DCS): It routes local field parameters from remote tank farms, sensor matrices, or motor control centers back to the central logic solver without requiring excessive signal cabling.
Continuous Process Networks: Manages critical automation loops in chemical, petrochemical, manufacturing, and energy industries, where communication interruptions can lead to entire production line shutdowns.
After installing CI820V1 3BSE025255R1, inspect the mounting and wiring, verify power and communication interfaces, complete the approved functional tests and confirm stable operation before returning the equipment to service.
