ABB 3BSE018135R1 CI858K01 PLC Module
Technical Parameters:
System Compatibility: Dedicated CEX-Bus expansion communication interface module designed for AC 800M controllers running ABB System 800xA and Compact Control Builder environments.
Communication Protocol: ABB DriveBus protocol for high-speed, real-time communication with ABB variable speed drives (such as ACS800 and ACS880 series).
Physical Interface: Fiber-optic communication interface designed to connect directly to optical drive channels for optical isolation and high noise immunity.
Data Transmission Rate: High-speed deterministic data throughput operating at up to 1.5 Mbit/s over optical fiber links.
Capacity & Limit: Connects up to 24 ABB drive units per CI858 module; supports up to 12 CEX-Bus interface modules per AC 800M controller rack.
Redundancy & Hot-Swap: Supports hot-swappable installation on the TP858 baseplate without interrupting controller execution or active system operation.
Operating Power Supply: Powered directly via the AC 800M CEX-Bus at 24 V DC (typical current consumption: 160 mA; max power dissipation approximately 3.5 W).
Conformal Coating & Rating: IP20 protection rating with ISA 71.04 G3 compliant harsh environment conformal coating for corrosion protection in severe industrial environments.
Operating Thermal Range: Industrial operating range from +5°C to +55°C (storage thermal range: -40°C to +70°C).
Physical Profile: Standard vertical CEX-Bus module form factor measuring 59 mm (W) x 185 mm (H) x 127.5 mm (D) with a net weight of approximately 0.5 kg.
Industrial Sectors:
Paper and Pulp Mills, Metal Processing and Steel Rolling, Mining and Material Handling, Chemical and Petrochemical Refining, Marine Heavy Propulsion, and Factory Automation.
Application Scenarios:
-
High-Speed Variable Speed Drive (VFD) Control: Mounted on the AC 800M CEX-Bus to manage real-time speed, torque, and position commands for multiple ABB ACS800/ACS880 drives over noise-immune fiber-optic DriveBus loops.
-
Synchronized Multi-Motor Drive Systems: Deployed in continuous manufacturing lines—such as paper machines, steel rolling mills, and printing presses—to ensure high-precision torque sharing and microsecond-level speed synchronization across multiple drive units.
-
High-Noise Heavy Industrial Telemetry: Used in high-voltage industrial environments to poll real-time drive diagnostics, motor currents, operational alarms, and fault history over optical links without susceptibility to electromagnetic interference (EMI).
-
System Automation Architecture Upgrades: Utilized during plant modernizations to integrate advanced ABB drive networks directly into the AC 800M controller backplane without requiring external serial-to-fiber gateway converters.
