CI627A 3BSE017457R1 ABB CONTROL UNIT
Technical Parameters:
System Compatibility: Submodule card designed for installation into host controllers (such as Advant Controller 400 series / AC 450) and MasterBus communication units within ABB System 800xA and Advant OCS architectures.
Communication Protocol: Supports MasterFieldbus (CS513) fieldbus communication protocol for high-speed deterministic process data exchange.
Physical Interfaces: Serial fieldbus interface connections designed for twisted-pair RS-485 or dedicated MasterFieldbus cable topology.
Data Transmission Speed: High-speed deterministic data exchange tailored for fast scan cycles and real-time process control loops.
Device Capacity: Connects and coordinates multiple fieldbus nodes, remote S100 I/O clusters, or MasterFieldbus-compatible field devices per channel.
Redundancy Support: Dual-channel capability supporting redundant fieldbus cabling configurations for high availability.
Operating Power Supply: Sourced internally from host backplane supply (5 V DC and 24 V DC backplane rails).
Diagnostic Telemetry: Integrated status LEDs indicating board operational state, line activity, and communication fault conditions.
Environmental & Thermal Specs: Industrial-grade design with IP20 enclosure rating when housed in standard system racks; operating temperature range from 0°C to +55°C.
Physical Profile: Standard MasterBus circuit board dimensions fitting dedicated CPU / communication module expansion slots with a net weight of approximately 0.4 kg.
Industrial Sectors:
Chemical and Petrochemical Processing, Oil and Gas Refining, Electric Power Generation, Metallurgy and Steel Mills, Paper and Pulp Manufacturing, and Heavy Industrial Automation.
Application Scenarios:
-
MasterFieldbus (CS513) Network Communication: Acts as the dedicated master interface board inside host controllers to communicate with remote I/O subsystems and field instruments.
-
High-Speed Inter-Controller Synchronization: Deployed in process plants to transfer real-time interlocking signals, status parameters, and dataset variables between controller nodes on the MasterFieldbus network.
-
Legacy DCS Plant Modernization: Used in Advant OCS and Master System architectures to maintain high-reliability fieldbus loops during phased automation platform upgrades.
-
Redundant Process Fieldbus Loops: Applied in critical processing units where redundant fieldbus lines are required to prevent network loss during cable breakage or electrical interference.
