Product Overview
When your industrial network demands reliable communication between controllers, the ABB CI869 provides a robust solution. This AC 800M communication interface connects to the AF 100 field bus through twisted pair (TWP) cables, enabling seamless data exchange with other AC 800M, AC 160, or connectivity servers. Designed for demanding environments, the CI869 supports both redundant cables and redundant communication interfaces to minimize downtime.
Technical Specifications Breakdown
The CI869 operates as a slave device on the ABB Advant Fieldbus 100 network, transmitting data at 1.5 Mbit/s. It consumes a typical 160 mA from a +24 V supply via the CEX-Bus. Key environmental ratings include an operating temperature range of +5 to +55 °C and storage from -40 to +70 °C. The module is IP20 protected per EN60529 and complies with corrosion protection class G3 per ISA 71.04. Dimensions are 59 mm wide, 185 mm high, and 127.5 mm deep, with a weight of 700 g including the base.
Industry Applications
In process control and manufacturing, the CI869 enables AC 800M controllers to act as AF 100 stations, receiving data from other field devices. It is also suitable for high-integrity systems, such as those requiring AF 100 redundancy. By using two CI869 modules, you achieve line and module redundancy, ensuring continuous operation even if one interface fails.
Installation & Setup Guidance
Mount the CI869 expansion unit onto the CEX-Bus backplane. The integrated DC/DC converter derives the required voltage from the +24 V supply through the bus, so no external power wiring is needed. Connect the twisted pair cables to the dedicated connector. For redundant operation, configure two CI869 modules as per the system manual. The module supports hot swap, allowing replacement without powering down the controller.
Maintenance & Reliability
Regular inspection of the twisted pair connections and verification of the +24 V supply voltage help maintain reliable communication. The CI869's G3 corrosion protection ensures long life in harsh industrial atmospheres. Its IP20 enclosure protects against solid objects, but keep the module free from dust and moisture. Periodic testing of redundant paths is recommended to confirm failover readiness.
Compatibility & Integration
The CI869 integrates with AC 800M controllers and works with AC 160 systems and connectivity servers over AF 100. It is used together with HI Controller systems. For the AC 100 OPC Server, pair the CI869 with the AF 100 hardware interface CI527A in the same node. The module supports up to 12 units on the CEX bus, making it scalable for larger configurations.
Selection Guide & Purchasing Advice
Before ordering, verify that your system requires AF 100 connectivity and that the CI869's slave mode matches your network topology. Confirm the availability of a +24 V supply on the CEX-Bus. For redundancy, plan for two CI869 modules. SpareTechPLC stocks the CI869 (article number 3BSE049110R1) and can advise on current lifecycle status and replacement options.
