Product Overview

• Part Number: CI868K01-eA
• Brand: ABB
• Matching System: AC800M series controller rack, compatible with Freelance, Symphony Plus control systems
• Type: Industrial Ethernet redundant communication interface module

• FunctionIt serves as the network gateway for AC800M controllers to connect with upper HMI, SCADA, inverters and field intelligent instruments. It realizes bidirectional data transmission of process parameters, fault alarms and control commands via industrial Ethernet. Supports redundant link automatic switching to avoid communication breakdown caused by single network cable failure, guaranteeing continuous stable data interaction for factory process control.

Core Features

1. Dual independent RJ45 10/100Mbps adaptive Ethernet ports, hot standby redundancy, seamless link failover
2. Multi-protocol compatibility: Modbus TCP, PROFINET, TCP/IP, UDP; connects third-party instruments and drives conveniently
3. 2kV reinforced isolation between backplane bus and Ethernet ports, strong anti-surge and anti-electromagnetic interference
4. PCB conformal coating, dustproof, moistureproof and oil-resistant, adapts power plant, chemical and metallurgy harsh cabinet environments
5. Front panel LED indicators for power, port link, running status and communication fault for quick troubleshooting

6. Standard AC800M rack plug-in installation, hot swappable without controller shutdown during replacement
