Product Introduction

The ABB CI867K01, part number 3BSE043660R1, is a dual-port Modbus TCP communication interface module designed for ABB AC800M and 800xA distributed control systems. It serves as an industrial network gateway to realize bidirectional data exchange between ABB DCS controllers and third-party automation devices, such as variable frequency drives, smart transmitters, power meters and HMI panels. Supporting both Modbus TCP master and slave modes, this module simplifies cross-brand equipment integration in process automation projects. It adopts industrial-grade circuit design and built-in electrical isolation, delivering reliable network transmission in harsh factory environments with temperature fluctuation, dust, vibration and electromagnetic interference. Widely used in power, petrochemical, pulp & paper, metallurgy and water treatment industries. It is an essential spare part for AC800M rack maintenance, communication module replacement and DCS system upgrade.

Content Details

Brand: ABB Model: CI867K01 Part No: 3BSE043660R1 Product Type: Modbus TCP Communication Interface Module Applicable System: ABB AC800M / 800xA DCS Support Protocol: Modbus TCP (Master / Slave) Ports: Dual RJ45 Ethernet ports The ABB CI867K01 3BSE043660R1 module is installed on the TP867 baseplate inside AC800M control rack. Its core function is to bridge the ABB controller CEX bus and Modbus TCP industrial Ethernet network. It collects field device data and forwards it to the main controller, meanwhile transmitting control commands from DCS to remote Modbus devices. Dual Ethernet ports provide flexible network wiring options to adapt to different on-site network architectures. This module supports hot-swap function. Engineers can replace the module without shutting down the whole control rack, greatly reducing system downtime during maintenance. Every unit undergoes full functional testing and aging screening before delivery to guarantee stable long-term continuous operation. Built-in isolation protection prevents surge and ground loop interference to protect the controller from network-side electrical damage. Optimized EMC performance effectively suppresses electromagnetic noise generated by high-power motors and inverters on site. It supports configuration via ABB Control Builder software, easy parameter setting, network diagnosis and communication status monitoring. LED indicators on the front panel display power status, link status and data transmission activity, helping maintenance staff quickly locate network communication faults. It can connect multiple Modbus TCP field instruments, expanding the communication capacity of the AC800M controller. Typical application scenarios include thermal power plant DCS control, chemical process monitoring, paper mill automation, metallurgical production line control and municipal sewage treatment system. When the original communication module fails, CI867K01 3BSE043660R1 can be directly replaced to restore Modbus TCP network communication between the DCS system and field smart devices. This module meets CE, UL and IEC industrial safety standards with IP20 protection rating. Compact modular design and durable electronic components support 24/7 continuous operation. Whether you prepare spare inventory for equipment overhaul or purchase components for DCS system retrofit projects, the ABB CI867K01 Modbus TCP communication module provides stable and reliable industrial Ethernet connectivity for your AC800M automation system.
