Adds ten rack positions to a supported serial-expansion architecture.
Product Overview
IC694CHS392A is the revision-A execution of the IC694CHS392 PACSystems RX3i serial expansion backplane. The backplane extends a supported main rack through the documented serial I/O expansion path.
The baseplate provides ten module positions and a dedicated leftmost position for a compatible serial-expansion power supply. Rack addressing and expansion-cable details belong to the installed-system record.
The A suffix remains part of the exact spare identity. Do not merge it with later IC694CHS392 revisions without an approved Emerson compatibility review.

Features
Accepts the compatible standard or high-capacity serial-expansion power supply in its dedicated position.
Keeps rack-number selection and cable topology tied to the controller project.
Preserves the revision-A hardware identity for maintenance records.
Applications
- PACSystems RX3i systems that use serially expanded I/O racks.
- Legacy installations where the original rack number and cable route must be preserved.
- Maintenance replacements requiring the same ten-slot mechanical arrangement.
- Spare planning for systems that cannot be migrated during a short outage.
Installation
- Back up the controller project and record the expansion rack number, cable route and installed modules.
- Remove power and verify the expansion chain is safe before disconnecting the rack.
- Set the replacement rack identity and reinstall modules in the documented positions.
- Restore power in the approved order, then verify rack recognition and every configured I/O point.

FAQ
What evidence should accompany an IC694CHS392A enquiry?
Provide the front and rear labels, rack number, power supply, installed module list, expansion cable code, CPU and project version.
Can IC694CHS392A be exchanged while the rack is energized?
No hot insertion or removal should be assumed for this baseplate. Isolate power and follow the approved RX3i service procedure.
Can a later IC694CHS392 revision replace IC694CHS392A automatically?
Do not assume interchangeability. Confirm Emerson revision notes, host support, mechanical details and the approved site configuration.
What configuration must be protected before changing IC694CHS392A?
Protect the rack number, module order, cable topology, power arrangement and controller hardware configuration.
What proves IC694CHS392A is ready after replacement?
Confirm exact revision, correct rack recognition, clean diagnostics and point-by-point operation of every installed module.
