Product Introduction

The ABB CI858, part number 3BSE018135R1, is a dedicated DriveBus communication interface kit designed for ABB AC800M and 800xA distributed control systems. It serves as the high-speed optical communication bridge between AC800M controllers and ABB variable frequency drives, transmitting torque references, speed commands and real-time drive status feedback via fiber optic DriveBus. The fiber transmission design effectively eliminates electromagnetic interference on heavy industrial sites. Built with industrial electronic components and robust EMC protection, this module maintains stable high-speed communication under harsh environments with vibration, temperature variation and strong electrical noise. Widely used in metallurgical rolling mills, paper machine main drives, mining conveyors and heavy-duty process automation. It is a vital spare part for AC800M rack maintenance, drive communication module replacement and motion control system upgrade.

Content Details

Brand: ABB Model: CI858 Part No: 3BSE018135R1 Product Type: DriveBus Communication Interface Kit Applicable System: ABB AC800M / 800xA DCS Communication: Fiber optic DriveBus Package Content: CI858 communication module + TP858 baseplate The ABB CI858 3BSE018135R1 kit is mounted on TP858 baseplate inside the AC800M control rack. It connects the controller CEX bus and ABB DriveBus fiber network. It sends motion control setpoints from the DCS controller to ABB drives, and uploads drive operating data including motor speed, torque, current and fault alarms back to the main controller. Each CI858 module can support connection with multiple ABB drives to realize coordinated multi-drive synchronous control. This module supports hot-swap function. Maintenance staff can replace the module without shutting down the whole control rack, greatly reducing production downtime during overhaul. It is powered through CEX bus, no extra external power supply required. Every unit undergoes comprehensive functional testing and aging screening before shipment to guarantee reliable 24/7 continuous operation. Fiber communication isolates control side and drive side, preventing ground loop and high voltage surge damage to the controller. It can be configured and diagnosed via ABB Control Builder software. LED indicators on the front panel show power status, fiber link and data transmission status, helping maintenance engineers quickly locate fiber break or communication faults. It is specially optimized for high-performance motion control and synchronous drive applications. Typical application scenarios include steel rolling mill drive control, paper machine multi-section drive, mining belt conveyor control and marine propulsion automation. When the original DriveBus communication module fails, CI858 3BSE018135R1 can be directly replaced to restore high-speed communication between DCS controller and ABB drive units. This module meets CE, UL and IEC industrial safety standards with IP20 protection rating. Compact modular rack structure and durable circuit design support long-term continuous heavy-duty operation. Whether you prepare spare inventory for equipment maintenance or purchase components for motion control system retrofit projects, the ABB CI858 DriveBus interface kit provides stable high-speed fiber communication for your AC800M drive control system.
