ABB CI853K01 Dual RS232-C Interfaces – Product Introduction

The ABB CI853K01 Dual RS232-C Interfaces Module is a versatile communication module designed for integrating serial devices into ABB control systems, particularly within the AC 800M and S800 I/O architecture. With two independent RS232-C communication channels, the CI853K01 enables reliable point-to-point data exchange with a wide range of third-party equipment, legacy instruments, and specialized serial devices used in industrial automation. Its robust design, flexible configuration capabilities, and high communication stability make it an ideal solution for applications requiring seamless serial connectivity in modern process plants.

Dual Independent RS232-C Communication Channels

The CI853K01 provides two fully independent RS232-C ports, each capable of managing its own serial communication session. This dual-channel design allows engineers to connect and operate two separate devices simultaneously using the same module. It supports common serial communication parameters such as baud rate, parity, stop bits, and data bits, ensuring compatibility with industry-standard RS232 equipment.

Devices typically connected via RS232 include barcode scanners, analyzers, meters, PLCs, UPS systems, terminal interfaces, and legacy process instrumentation. With the CI853K01, these devices can be seamlessly integrated into ABB’s automation environment for monitoring, data logging, and supervisory control.

Seamless Integration with AC 800M and S800 I/O

Engineered for ABB’s modular control platforms, the CI853K01 integrates smoothly into the AC 800M controller and S800 I/O system. Once installed, the module is recognized automatically by ABB’s engineering tools, allowing technicians to configure serial parameters and communication drivers through intuitive software menus.

The module supports Modbus RTU (master or slave) and other serial protocols, depending on application requirements. This flexibility makes it suitable for both modern and legacy automation architectures where serial-based communication remains essential.

Robust Industrial Performance

The CI853K01 is built for demanding industrial environments, offering:

·

Strong electromagnetic compatibility (EMC)

·

·

High resilience against vibration and electrical noise

·

·

Wide operating temperature range

·

·

Long service life for continuous 24/7 operation

·

These industrial-grade characteristics make the module reliable for use in oil and gas, chemical production, power plants, water treatment facilities, manufacturing systems, and transportation infrastructures.

Its durable construction ensures stable operation even when connected to older devices that may generate noisy or unstable signals.

Advanced Diagnostics and System Transparency

Comprehensive diagnostic support is one of the standout features of the CI853K01. The module provides real-time monitoring of communication status, error counts, port activity, and device connection health. Faults such as framing errors, parity mismatches, or communication timeouts are immediately detected and reported to the control system.

These diagnostics help maintenance teams rapidly identify and resolve issues, reducing downtime and improving system reliability. The module’s transparency also makes troubleshooting legacy serial devices easier, especially in complex or distributed systems.

Flexible Applications in Modern and Legacy Systems

Because RS232 remains widely used in industrial environments, the CI853K01 is a valuable bridge between modern control platforms and legacy operational equipment. Typical applications include:

·

Integrating laboratory analyzers into process control

·

·

Connecting serial-only PLCs, drives, or sensors

·

·

Gathering measurement data from standalone meters

·

·

Supervising cooling systems, UPS units, or environmental monitors

·

·

Communicating with terminal or HMI interfaces

·

Its flexibility ensures continued compatibility with equipment that would otherwise require replacement.
