Product Description
The ABB CI867K01 is a high-speed communication interface designed for the AC 800M controller series within the 800xA automation platform. This module enables seamless integration between the controller and external Modbus TCP-compliant devices, such as motor drives, power meters, and third-party PLCs. It functions as both a Master (Client) and a Slave (Server) simultaneously, providing a robust gateway for real-time data exchange. The “K01” kit typically includes the CI867 interface module and the necessary TP867 baseplate for rail mounting and electrical connection.
Application Fields
This interface is extensively used in power management systems, water treatment facility automation, and industrial manufacturing plants where multi-vendor equipment integration is required. It is the primary choice for connecting AC 800M controllers to remote I/O systems, intelligent electronic devices (IEDs) in electrical substations, and HVAC control units via standard Ethernet infrastructure.
Product Specifications
- Weight: 0.55 kg (including baseplate)
- Dimensions: 186 mm x 59 mm x 127 mm
- Origin: Sweden / Estonia

Operational Precautions
- Ensure the module is firmly clicked into the TP867 baseplate before applying power to prevent arcing or communication drops.
- Verify that the Ethernet cables are shielded (Cat5e or higher) and properly grounded to mitigate industrial electromagnetic noise.
- Limit the number of Modbus transactions per second according to the module’s buffer capacity to prevent network congestion or watchdog timeouts.
- Always update the CI867 firmware in synchronization with the AC 800M controller firmware to ensure full feature compatibility and security patching.
