ABB identifies 3BSE092695R1 as the article number for CI873A and specifies the package as CI873A plus TP867 baseplate. The published hardware data also gives the physical dimensions, weight, environmental limits, connector type, and typical supply current. (ABB 800xA 硬件选择器)
AC 800M Backplane and Ethernet Communication
The CI873A uses the AC 800M CEX-Bus interface to connect its communication electronics to the controller architecture. Its expansion unit incorporates CEX-Bus logic, a communication unit, and a DC/DC converter that derives the required operating voltage from the +24 V supply through the CEX-Bus. (ABB 800xA 硬件选择器)
For network communication, the associated TP867 baseplate provides two RJ-45 Ethernet connectors. ABB specifies CH1 as the connector used for the 100 Mbit/s communication path. The interface operates as a master and supports both EtherNet/IP and DeviceNet protocols. (ABB 800xA 硬件选择器)
The CI873A also supports module redundancy and hot swap. ABB specifies support for up to 6 redundant CI873A pairs from System 800xA 5.1 FP4. The module does not provide line redundancy. (ABB 800xA 硬件选择器)

Q: What is the typical 24 V DC current consumption?
A: ABB specifies a typical 24 V consumption of 160 mA. The supply reaches the communication interface through the CEX-Bus.
Field Installation Guidelines
- Install the CI873A with the specified TP867 baseplate and establish the required CEX-Bus connection to the AC 800M controller architecture.
- Connect the Ethernet network through the RJ-45 interface provided on the TP867 baseplate. Use CH1 for the specified 100 Mbit/s communication path.
- Route Ethernet communication cables separately from high-voltage power wiring and high-current switching conductors to reduce electromagnetic coupling.
- Maintain the specified operating temperature range of 0 to +55 deg C and avoid installation locations that exceed the published humidity and environmental limits.
- Verify that the installation enclosure provides the required protection because the module itself has an IP20 protection class.
- Before commissioning, verify the configured EtherNet/IP or DeviceNet network parameters and confirm communication status through the control system diagnostics.
- For redundant configurations, verify the CI873A pair configuration and controller software compatibility before replacing or adding communication modules.
- Use only software and controller configurations supported by the applicable System 800xA and Compact Control Builder versions.
