Technical Specifications

Verification & Quality Control

Our inspection procedure for the Honeywell TK-PRR021 includes:

1. Confirming the TK-PRR021 catalog number.
2. Matching the 51309288-275 ordering number.
3. Checking the product label and revision.
4. Inspecting the chassis connector.
5. Checking the module enclosure.
6. Inspecting accessible PCB surfaces.
7. Looking for corrosion, oxidation or physical damage.
8. Checking front-panel indicators.
9. Recording serial-number information where available.
10. Taking actual product photographs.
11. Performing functional testing where a compatible C200 system is available.
12. Applying anti-static protection before packing.
13. Using shock-resistant outer packaging for international transportation.

Procurement Verification

Before placing an order, customers should confirm:

Model: TK-PRR021
Part Number: 51309288-275
System: Honeywell C200
Function: Redundancy Module
Chassis Requirement: 2 slots

It is also worth checking the revision letter on the customer's existing unit. Used inventory listings show versions such as REV G, REV H and REV K, so the revision should be compared before a replacement is finalized.

Replacement Note

For an exact replacement, the customer should provide:

1. Existing TK-PRR021 photo
2. Complete part number
3. Hardware revision
4. C200 chassis configuration
5. Controller redundancy configuration

This is important because TK-PRR021 is a redundancy-specific module, and it should not be treated as a general-purpose C200 I/O module.
