Product Details

CI626V1 3BSE012868R1 Product Description

The ABB CI626V1 (part number 3BSE012868R1) is a high-performance communication interface module engineered for seamless integration within the ABB AC800M Distributed Control System (DCS) architecture. Designed to serve as the backbone of inter-module communication, the CI626V1 enables reliable, deterministic data exchange across the control layer, I/O subsystems, and supervisory networks in demanding industrial environments. Whether deployed in power generation, oil and gas, chemical processing, water treatment, or advanced manufacturing, this module delivers the signal integrity, protocol compatibility, and long-term serviceability that modern automation platforms require.

The CI626V1 3BSE012868R1 is not a standalone component — it is a precision-engineered node within the broader ABB AC800M control architecture. Its value is fully realized when deployed alongside complementary modules that together form a cohesive, redundant, and scalable automation platform.

At the controller layer, the CI626V1 interfaces directly with the ABB PM864A and PM865A processor modules, which serve as the computational core of the AC800M system. These CPUs rely on communication interfaces like the CI626V1 to extend their reach across fieldbus networks and remote I/O clusters. For redundant controller configurations, the ABB PM866A dual-redundant processor module pairs with the CI626V1 to ensure uninterrupted control loop execution even during module replacement or network fault events.

At the I/O layer, the CI626V1 coordinates signal routing between the controller and distributed I/O modules such as the ABB AI810 analog input module and the ABB DO810 digital output module, both mounted on S800 I/O backplanes. The CI626V1 ensures that process variable data — temperature, pressure, flow, and discrete status signals — is transmitted with minimal latency and maximum fidelity to the controller for real-time decision-making.

At the communication layer, the CI626V1 works in concert with the ABB CI854A PROFIBUS DP master module and the ABB CI857 PROFINET interface module to bridge legacy fieldbus devices and modern Ethernet-based instrumentation into a unified control network. This multi-protocol capability is essential for brownfield upgrades where existing PROFIBUS field devices must coexist with newer PROFINET-enabled sensors and actuators.

For power distribution integrity, the ABB SD821 and SD822 power supply modules provide stable 24 VDC to the rack, ensuring that the CI626V1 and adjacent modules operate within their specified electrical parameters even under transient load conditions. Redundant power supply configurations using dual SD822 units eliminate single points of failure at the power layer.

At the HMI and supervisory layer, the CI626V1 supports data aggregation that feeds into ABB 800xA System (Extended Automation System 800xA), enabling operators to monitor communication health, module diagnostics, and process variable trends from a centralized engineering workstation. Integration with the 800xA platform also enables online firmware management and remote module diagnostics without process interruption.

For terminal and wiring infrastructure, the ABB TB820V2 media redundancy module and associated S800 I/O terminal units provide the physical connection layer between field cables and the I/O backplane, ensuring that the CI626V1's communication pathways are supported by robust, vibration-resistant wiring terminations suitable for industrial cabinet environments.

Power Generation & Utilities: In combined-cycle power plants and hydroelectric facilities, the CI626V1 enables real-time communication between turbine control loops, generator protection relays, and the plant-wide DCS. Its deterministic communication timing supports the sub-second response requirements of load-following and frequency regulation applications.

Oil, Gas & Petrochemical: Offshore platforms and onshore refineries deploy the CI626V1 within safety-instrumented system (SIS) architectures where communication reliability between the ESD controller and process DCS is critical. The module's compatibility with redundant AC800M configurations supports SIL 2/3 loop integrity requirements.

Water & Wastewater Treatment: Municipal water authorities use the CI626V1 to integrate remote pump stations, chemical dosing systems, and SCADA networks into a centralized AC800M control platform. Its wide operating temperature range and IP20 protection class make it suitable for both climate-controlled control rooms and field-mounted enclosures.

Mining & Metallurgy: In ore processing and smelting operations, the CI626V1 facilitates communication between high-power drive systems, conveyor control PLCs, and the plant DCS, supporting coordinated production sequencing and energy optimization across multi-zone processing lines.

Packaging & Discrete Manufacturing: High-speed packaging lines and automotive assembly plants leverage the CI626V1's PROFIBUS DP capability to synchronize motion controllers, vision systems, and robotic end-effectors with the central AC800M production management controller, reducing inter-device communication latency and improving overall equipment effectiveness (OEE).

Q1: Is the CI626V1 3BSE012868R1 compatible with both AC800M and AC800F controller platforms? The CI626V1 is specifically designed and validated for the ABB AC800M controller platform. While ABB produces communication interface modules for the AC800F series (such as the CI860), the CI626V1 is not cross-compatible with AC800F racks. Always verify the target controller series and firmware revision before ordering to ensure full system compatibility. Our technical team can assist with cross-referencing part numbers for mixed-platform installations.

Q2: Can the CI626V1 be hot-swapped during live process operation, and what redundancy configurations are supported? The CI626V1 supports hot-swap replacement in AC800M systems configured with redundant communication paths, provided the system has been engineered with dual CI626V1 modules in a redundant pair configuration. In non-redundant single-module deployments, module replacement requires a controlled process hold. For critical continuous processes, ABB recommends deploying redundant CI626V1 pairs alongside redundant PM866A processor modules to achieve full controller and communication redundancy with bumpless switchover capability.

Q3: What does the 12-Month Warranty cover, and how is long-term spare parts availability managed? Every CI626V1 3BSE012868R1 unit supplied by NANKMOS is covered by a 12-Month Warranty against manufacturing defects and functional failures under normal operating conditions. Prior to dispatch, each unit undergoes a comprehensive functional test protocol including communication loop-back testing, power consumption verification, and firmware version confirmation. For long-term maintenance planning, NANKMOS maintains a managed inventory of AC800M platform modules — including CI626V1, PM864A, AI810, and DO810 — to support planned maintenance shutdowns, emergency replacements, and multi-year service contracts.
