CI857K01 3BSE018144R1 ABB CONTROL UNIT

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: INSUM (Integrated System for Motor Control and Protection) protocol based on LonWorks (LonTalk) fieldbus architecture.

Physical Interfaces: Integrated fieldbus connectivity interface on the TP857 baseplate for direct coupling with INSUM network loops.

Data Transmission Rate: Standard LonWorks network transmission speeds optimized for real-time motor status telemetry and control commands.

Capacity & System Limits: Interfaces with up to 128 INSUM Motor Control Units (MCUs) per CI857 module; supports up to 12 CEX-Bus interface modules per AC 800M controller rack.

Redundancy & Hot-Swap: Supports hot-swappable installation on the TP857 baseplate without interrupting controller execution or active system operation.

Operating Power Supply: Sourced directly via the AC 800M CEX-Bus at 24 V DC (typical current consumption: 160 mA).

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: Standard operating envelope 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:

Chemical and Petrochemical Processing, Oil and Gas Refining, Electric Power Generation and Utilities, Mining and Heavy Metallurgy, Water and Wastewater Infrastructure, and Continuous Process Manufacturing.

Application Scenarios:

1. Intelligent Motor Control Center (MCC) Integration: Mounts on the AC 800M CEX-Bus to link central System 800xA control systems directly with INSUM Motor Control Units (MCUs), enabling centralized motor control, status monitoring, and fault management.

2. Real-Time Motor Diagnostic Telemetry: Serves as the primary communication bridge to poll dynamic operational data—such as motor current, thermal overload levels, operating hours, and trip alarms—from distributed low-voltage motor starters.

3. System 800xA Plant Asset Management: Integrated into large process plants to provide predictive maintenance telemetry and device status information to higher-level asset management platforms.

4. Process Automation System Upgrades: Utilized during plant modernizations to incorporate existing INSUM motor management field networks into modern AC 800M controllers without rewiring motor control loops.
