Ethernet Fieldbus and Redundancy Characteristics

The CI845 provides Ethernet fieldbus communication for ABB Ability System 800xA installations. It can operate as a single interface or as part of a redundant communication arrangement.

Furthermore, the 19.2 to 30 V input range supports the specified DC supply conditions. The module dissipates 5 W during operation, while the stated operating temperature range extends from -40 deg C to +70 deg C.

For industrial network installation, maintain appropriate separation between Ethernet communication wiring and high-current or high-voltage conductors. Use the applicable ABB network architecture and grounding practices for the installed System 800xA configuration.

Frequently Asked Questions

Q: Can the CI845 3BSE075853R1 operate in a redundant configuration?
A: Yes. The supplied product information specifies that the CI845 can operate as either a single or redundant Ethernet Fieldbus Communication Interface Module.

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

Q: What environmental temperature range does the module support?
A: The 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. Verify the CI845 model and complete order number before installation.
2. Confirm that the available DC supply remains within the specified 19.2 to 30 V range.
3. Install the module according to the applicable ABB System 800xA hardware arrangement.
4. Route Ethernet communication cables separately from high-current power conductors where practical.
5. Maintain proper cable shielding and grounding according to the plant's industrial Ethernet installation standard.
6. Check connector seating and cable routing before energizing the communication interface.
7. For redundant configurations, verify both communication paths and associated network connections before commissioning.
8. Confirm the ambient temperature remains within -40 deg C to +70 deg C during operation.
9. Do not use the stated shipping dimensions as the physical installation envelope; verify the actual mechanical dimensions from the applicable ABB installation documentation.
