01Technical Summary
Honeywell TC-PRR021 is a redundancy module associated with the Series A and C200 installed-base hardware family. It is used where the original control-system design calls for the TC redundancy hardware. Because Honeywell announced a lifecycle transition for the Series A I/O family, service replacement and migration should be evaluated together.

03Features
- Provides the model-specific redundancy function used in supported Honeywell control configurations.
- Supports installed-base maintenance where TC-PRR021 is identified in the approved system design.
- Uses a distinct model identity from the separately listed TK-PRR021 coated variant.
- Fits lifecycle planning for legacy Series A I/O and C200 or C200E installations.
- Requires configuration-level verification so the redundancy architecture remains consistent after service work.

Product type
Redundancy Module
04Compatibility
- Verify the C200 or C200E controller architecture, chassis, processor, and system release before selection.
- Confirm the complete redundant pair and associated hardware rather than replacing a module by appearance.
- TK-PRR021 is separately listed as a coated redundancy module and is not an automatic substitute.
- Legacy Series A I/O installations should be assessed against Honeywell lifecycle and migration guidance.
05Replacement
- For like-for-like maintenance, match TC-PRR021 and the installed hardware revision exactly.
- Back up the control configuration and document the redundancy status before beginning service.
- Honeywell migration paths include C300 with retained Series A I/O through an FTE Bridge, or UOC and vUOC solutions with Series A I/O; project assessment is required.
- Do not select a migration target solely from the model name; confirm the full I/O, network, chassis, and software scope.
06FAQ
What is Honeywell TC-PRR021?
It is a Honeywell redundancy module associated with Series A and C200 or C200E installed-base hardware.
Is TK-PRR021 the same ordering model?
No. Honeywell lists TK-PRR021 separately as a coated redundancy module.
Can TC-PRR021 be replaced without checking the system release?
No. The chassis, processor, system release, and configured redundancy architecture must be verified.
What lifecycle issue should be considered?
Honeywell issued a phase-out notice for the Series A I/O family effective January 31, 2023.
Are migration options available?
Honeywell describes migration paths using C300 with an FTE Bridge or UOC and vUOC solutions, subject to a project-specific assessment.
Is a verified product weight available?
No verified manufacturer weight is included, so no weight is displayed.
