ABB Industrial Ethernet and System 800xA Communication

The CI845 provides an Ethernet fieldbus communication interface for ABB Ability System 800xA architectures. System designers can configure the module as a single interface or within a redundant communication arrangement.

Furthermore, the module receives its operating supply within the specified 19.2 to 30 V input range and dissipates approximately 5 W under the stated specification. The -40 deg C to +70 deg C operating range supports installation in industrial control environments.

The CI845 belongs to ABB's industrial control communication architecture rather than serving as a conventional discrete or analog I/O channel. Therefore, installation should preserve the required Ethernet communication path, module mounting integrity, and electrical grounding arrangement.

Frequently Asked Questions

Q: Can the CI845 3BSE075853R1 operate in a redundant configuration?
A: Yes. The supplied specification identifies the CI845 as suitable for single or redundant configuration.

Q: What supply voltage does the CI845 require?
A: The specified input voltage range is 19.2 to 30 V.

Q: What environmental temperature range does the CI845 support?
A: The specified operating range is -40 deg C to +70 deg C, while the storage range is -40 deg C to +85 deg C.

Field Installation Guidelines

1. Mount the CI845 securely according to the System 800xA hardware installation arrangement.
2. Verify that the supply voltage remains within the specified 19.2 to 30 V range before energizing the module.
3. Maintain separation between Ethernet communication wiring and high-voltage or high-current conductors.
4. Route communication cables to minimize exposure to electromagnetic interference from drives, contactors, and switching equipment.
5. Connect cable shields and protective earth according to the applicable ABB installation documentation and site grounding design.
6. Provide adequate enclosure ventilation so the module remains within its -40 deg C to +70 deg C operating range.
7. For redundant configurations, verify both communication paths before placing the system into service.
8. Inspect connectors and cable terminations for mechanical retention and correct routing before commissioning.
