CI855-1 3BSE018134R1 Digital Module

　　Core Technical Specifications

Communication Architecture: Based on the MasterBus 300 (MB300) protocol, it supports real-time data interaction between the AC 800M controller and I/O modules, fieldbus devices, and other control systems. It integrates dual Ethernet ports (RJ45), supports network redundancy design, and offers data transmission rates up to 100 Mbps. It is compatible with mainstream industrial protocols such as PROFIBUS DP, Modbus TCP, IEC 61850, EtherCAT, and Profinet.

Physical Characteristics: Dimensions: 59mm × 127.5mm × 185mm; Weight: 0.621kg; IP20 protection rating; Operating temperature: 0℃-60℃; Storage temperature: -40℃-85℃; Vibration/shock resistance meets industrial standards; DIN rail mounting compatible.

Function Expansion: Supports the DriveBus protocol (designed specifically for ABB drives); a single module can manage up to 24 inverters. Logical bus topology is built through branch units (NDBUs), optimizing wiring complexity.

Electrical Requirements: 24V/150mA power supply (provided by CEX bus), hot-swappable, compatible with ABB AC800M controllers and S800/S900 distributed I/O modules.

　　Application Scenarios and Advantages

Power Industry: Adapted to small and medium-sized synchronous generators, hydropower/thermal power distributed energy stations, supporting grid-connected voltage stabilization, power factor regulation, and IEEE 2A/2B power stabilizer standards, compatible with SCADA system data interaction.

Industrial Automation: Enables efficient data exchange and collaborative control between equipment in heavy industries such as petroleum, chemical, and steel, supporting redundant configurations (CPU/communication/power supply redundancy) to improve system reliability.

Process Industry: Integrates with Freelance distributed control systems, supports FOUNDATION Fieldbus, PROFIBUS, HART, and other fieldbuses, adapts to AC700F/AC800F controllers, and enables open-loop/closed-loop control and remote site data transmission.

Special Environments: Compliant with DNV, BV, and LR classification society certifications, suitable for offshore platforms and ship electrical systems, exhibiting outstanding resistance to salt spray corrosion and adaptability to wide temperature environments.

Renewable Energy: Optimizes grid connection efficiency for wind/hydropower generation, connects frequency converters via DriveBus protocol (up to 24 units per unit), and is compatible with segmented drive systems in rolling mills, paper machines, etc.

Expansion Capabilities: Constructs a star topology through branch unit NDBU, supports OPC UA/cloud platform connections, and is compatible with PM40 power modules to expand to 40A excitation current, meeting high power requirements.

　　Installation and Maintenance Points

Configuration Tools: Configures bus addresses via DIP switches or system tools (such as Control Builder F), supports local/remote parameter settings, and is compatible with CMT1000 commissioning tools and Modbus/TCP remote commissioning.

Fault Diagnosis: Built-in online diagnostic function, supports event alarm processing and time stamping, and provides predictive maintenance support by combining COMTRADE waveform analysis.

Routine Maintenance: Regularly check wiring for secure connections, clean module surfaces and internal dust, and ensure good heat dissipation; supports hot-swapping to reduce system downtime.

　　Compatibility and Protocol Support

Protocol Compatibility: Integrates the MasterBus 300 (MB300) protocol, enabling point-to-point communication with System 800xA controllers and legacy Advant OCS systems. Supports open protocols such as PROFINET and EtherCAT, ensuring compatibility with third-party devices.

System Integration: Adapts to AC800M/PEC controllers, powered via the CEX bus, supports CPU/communication/power redundancy, and can connect to S800 I/O modules, achieving high-integrity I/O with HART protocol verification and SIL3 certification.

　　Performance Comparison and Expandability

Comparison with CI855K01: CI855-1 supports higher data transfer rates (100 Mbps vs 10 Mbps), adds EtherCAT/Profinet protocol compatibility, and enhances redundancy design and I/O module expansion capabilities.

Combined with the UNITROL series: Connects to the PM40 power module via CAN bus, extending the excitation current to 40A, suitable for high-power industrial scenarios; supports the OPC UA open architecture, connecting to cloud platforms and mobile devices for data analysis.

Expansion capabilities: Adapts to S800/S900 I/O modules, supports HART, time stamps, and I/O redundancy, compatible with ABB Freelance rack-mount systems, achieving PLC and DCS function integration.

Summary: As a core component of ABB’s industrial communication interface modules, the CI855-1, with its multi-protocol compatibility, redundant design, wide temperature adaptability, and high reliability, is an ideal solution for industrial automation and power systems. Its modular design and expansion capabilities can flexibly adapt to different scenario requirements, while complying with international safety and performance standards, ensuring long-term stable operation.
