What Is the ABB CI871A?
When your PROFINET IO devices need reliable, high-speed connectivity to an ABB AC 800M controller, the CI871A communication interface delivers a proven solution. This module acts as a PROFINET IO master, bridging the AC 800M system with Ethernet-based field devices. Designed for demanding industrial environments, the CI871A integrates seamlessly with System 800xA versions 6.0.3.3, 6.1.1, and subsequent releases.
Technical Specifications Breakdown
The CI871A operates as a PROFINET IO master with a transmission speed of 10/100 Mbit/s, ensuring fast data exchange. It uses an RJ-45 female (8-pin) connector and draws a typical 24 V consumption of 160 mA. The module supports hot swap and module redundancy, minimizing downtime during maintenance. With an operating temperature range of +5 to +55 °C (+41 to +131 °F) and storage from -40 to +70 °C (-40 to +158 °F), it suits harsh factory floors. The IP20 protection class and pollution degree 2 compliance (per IEC/EN 61131-2) ensure reliable operation in typical industrial settings.
Industry Applications
In automotive assembly lines, the CI871A connects PROFINET IO drives and sensors to the AC 800M controller, enabling real-time control and diagnostics. For process industries like chemical plants, it integrates remote I/O stations and valve actuators, supporting module redundancy for critical loops. The G3 corrosion protection (ISA 71.04 compliant) makes it ideal for environments with corrosive gases, such as wastewater treatment facilities.
Installation & Setup Guidance
Mount the CI871A on a TP867 baseplate, which provides two RJ45 Ethernet connectors. Use only the CH1 connector for PROFINET IO connection, as it supports 100 Mbit/s. Connect the Ethernet cable to the PROFINET IO network through an external Ethernet switch. The module draws power via the CEX-Bus from a +24 V supply. Ensure the CEX-Bus does not exceed 12 units for optimal communication.
Maintenance & Reliability
The CI871A's hot swap capability allows replacement without powering down the system, reducing production interruptions. Its module redundancy feature provides a backup communication path, enhancing system availability. Regular inspection of the RJ-45 connector and Ethernet cable for physical damage helps maintain signal integrity. The wide storage temperature range (-40 to +70 °C) protects the module during plant shutdowns.
Compatibility & Integration
The CI871A works exclusively with ABB AC 800M controllers and System 800xA 6.0.3.3, 6.1.1, and later versions. It supports PROFINET IO master operation at 10/100 Mbit/s. The module does not support line redundancy but offers module redundancy and hot swap. It is also compatible with HI controllers, expanding its use in safety-related applications.
Selection Guide & Purchasing Advice
Before ordering, verify your System 800xA version is 6.0.3.3 or newer. Confirm the CEX-Bus slot availability and that the total units on the bus do not exceed 12. The CI871A (article number 3BSE092693R1) includes the baseplate weight of 700 g (1.5 lbs) and dimensions of 59 mm width, 185 mm height, and 127.5 mm depth.
