CI853 3BSE018103R1 | ABB | System 800xA Dual RS-232 Communication Interface

Product Overview

The ABB CI853 (3BSE018103R1) serves as a high-performance, dual-channel RS-232 communication interface for the AC 800M controller family. This module enables seamless point-to-point connectivity with third-party devices using COMLI or MODBUS RTU protocols. By mounting directly to the CEX-Bus, the CI853 expands the controller's peripheral reach to include modems, printers, and legacy PLC systems. We supply this unit as 100% brand new original equipment, ensuring full technical compliance for your mission-critical automation infrastructure.

Engineering Advantages

• Enhanced Connectivity Density: The CI853 features two independent channels in a single 59 mm wide module. This high-density design optimizes cabinet space while providing versatile communication paths for varied serial peripherals.

• High Integrity System Compatibility: This interface works directly with High Integrity (HI) Controllers. This allows engineers to implement non-interfering serial communications within safety-critical environments without compromising system SIL ratings.

• Harsh Environment Resilience: Standard G3 conformal coating protects the internal circuitry against atmospheric pollutants and corrosive gases. This feature ensures long-term hardware availability in demanding sectors like oil and gas or chemical processing.

• Simplified Maintenance with Hot Swap: The hardware supports Hot Swap functionality. Technicians replace the module while the system remains energized, significantly reducing Mean Time to Repair (MTTR) and avoiding costly process interruptions.

• Global Maritime Approval: Comprehensive marine certifications (ABS, DNV-GL, etc.) qualify this module for offshore platforms and vessel automation, where vibration and humidity requirements exceed standard industrial specs.

FAQs

• Can the CI853 act as both a Master and a Slave? Yes. The CI853 supports both Master and Slave configurations for COMLI and MODBUS RTU protocols, providing maximum flexibility when integrating with third-party SCADA or PLC systems.

• What cable type does the RJ-45 port require for RS-232? The unit utilizes an 8-pin RJ-45 connector for serial signals. You must use specifically pinned adapters or cables to convert the RJ-45 interface to standard DB9 or DB25 connectors required by your field devices.

• Does this kit include the baseplate? Yes. The 3BSE018103R1 (CI853K01) designation identifies the complete kit, which includes the CI853 communication module and the necessary TP853 baseplate for CEX-Bus mounting.

• Is this a genuine, factory-sealed ABB unit? Absolutely. We guarantee that this CI853 3BSE018103R1 is 100% Brand New original hardware. It ships in factory packaging with all security seals and documentation intact.
