More Information

Overview Manuals Specifications FCI Pairing ModuleBus Setup Hot Configuration

Features:

  • S800 I/O station interface: CI840A gathers supervision data and manages connected I/O modules.
  • Redundant operation: Line and module redundancy plus hot swap are documented.
  • Maintenance functions: HART pass-through and Hot Configuration In Run support service workflows.

CI840A belongs at the head of an S800 I/O station, not in the AC 800M CEX-Bus communication-interface position.

TU846 is used for redundant I/O, while TU847 supports non-redundant I/O; the selected base defines the station wiring arrangement.

A replacement plan should include station address, fieldbus path, ModuleBus map, HART requirements, OSP behavior, and I/O acceptance tests.

Availability is subject to Apter Power's current inventory and sourcing confirmation.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
When should CI840A 3BSE041882R1 use TU846 instead of TU847?
Use the MTU arrangement that matches the approved redundant or non-redundant I/O design, fieldbus wiring, power feeds, and station documentation.
How should CI840A compatibility be checked with the parent controller?
Confirm PROFIBUS DP-V1 master support, hardware definitions, station configuration, redundancy functions, controller release, and the project hardware tree.
What should be recorded before replacing CI840A 3BSE041882R1?
Record the station address, MTU article, fieldbus cables, ModuleBus order, power connections, redundancy state, diagnostics, and all module positions.
How does CI840A HART pass-through affect maintenance planning?
Ensure the controller, engineering tools, connected I/O modules, and field-device path all support the intended HART maintenance workflow.
What should be checked if a CI840A station loses multiple I/O modules?
Check interface power, MTU connections, ModuleBus continuity, fieldbus status, address settings, module sequence, OSP events, and station diagnostics.
How should Hot Configuration In Run be controlled with CI840A?
Use the project-approved procedure, verify supported hardware changes, keep the plant safe, monitor diagnostics, and document the final hardware tree.
What tests confirm CI840A redundancy after service?
Test each fieldbus path and module position separately, confirm valid I/O data, inspect alarms, and verify recovery without unexpected output behavior.
What should a CI840A procurement RFQ include?
Provide quantity, condition, destination, date, full label, TU846 or TU847 identity, station layout, redundancy requirement, and documentation needs.
