CI845
ABB
Overview
The CI845 is an Ethernet FCI Module from ABB. It extends the ABB product portfolio connectivity through its onboard communication interface.
Application & Technical Notes
As an ethernet fci module, the CI845 is intended for deployment in panel-based control cabinets and machine enclosures where the ABB product portfolio equipment is installed. It bridges the controller to higher-level networks, HMIs, SCADA and peer devices, carrying configuration, process data and diagnostics.
Key published characteristics include a range 19.2 ... 30 V rating. These values should be confirmed against the current manufacturer datasheet before final selection, as options and suffixes vary by configuration.
Maintenance & Diagnostics
Avoid condensation — the rated humidity is 5 to 95 %, non-condensation; store and operate the module in a dry, pollution-degree-appropriate enclosure. Confirm network addressing, baud/rate and topology match the rest of the system; keep firmware consistent across the cell. Always de-energise the circuit and follow lock-out/tag-out before handling; refer to the official instruction bulletin for service procedures.
Sourcing & Procurement
When sourcing the CI845, distinguish three supply tiers: (1) genuine ABB stock from an authorised distributor; (2) compatible equivalents or surplus/NOS (new-old-stock) from third parties; (3) alternative parts offering equivalent function. Genuine supply carries the full warranty and traceability; compatible or alternative items may be cheaper but should be validated for form, fit, firmware and certification before use in a live system. PLCXpert publishes this page as an independent reference and does not sell the part — verify every claim with the manufacturer or your distributor.
Match the protocol, connector and topology to the rest of the ABB product portfolio network and to the peer devices already installed. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.
