TK-FXX102 Honeywell C200 10-Slot Coated Rack

Overview

The Honeywell TK-FXX102 97126875-A01, also identified by the base model TK-FXX102, is a 10-slot coated rack assembly with distributed DC power rails for industrial control hardware. It accepts a nominal 24 VDC input and provides 5.1 VDC logic power, 24 VDC power, and 3.3 VDC power according to the supplied specifications. The rack supports physical module installation and power distribution within a compatible Honeywell control system.

Hardware Specifications

DC Power Distribution and Backplane Characteristics

The TK-FXX102 distributes DC power to compatible control hardware through its rack power architecture. The specified 5.1 VDC logic rail operates within a tolerance of +/- 1%, while the distributed logic current has a listed maximum of 40 A. The input supply accepts 24 VDC nominal with a maximum input current of 10 A.

The supplied ratings list separate current values for the 5.1 VDC, 24 VDC, and 3.3 VDC rails. However, the available data does not define the conditions associated with each paired rating or confirm the simultaneous loading limits across all rails. Therefore, verify the applicable power budget and rack compatibility against the manufacturer’s documentation before connecting modules.

Frequently Asked Questions

Q: What input supply does the TK-FXX102 require?

A: The supplied specification identifies a nominal 24 VDC input with a maximum input current of 10 A.

Q: What power rails does the rack provide?

A: The listed rails are 5.1 VDC, 24 VDC, and 3.3 VDC. Confirm the output current limits and loading conditions from the applicable manufacturer documentation before system commissioning.

Q: Does the available specification confirm hot-swap support?

A: No. The supplied information does not establish hot-swap capability. Check the rack and installed module documentation before inserting or removing modules under power.

Field Installation Guidelines

1. Verify rack compatibility: Confirm that the TK-FXX102 matches the intended Honeywell system, chassis arrangement, and supported modules.
2. Inspect the assembly: Check the rack, connectors, and accessible power interfaces for physical damage before installation.
3. Verify the DC supply: Confirm the supply polarity and nominal 24 VDC input before energizing the rack.
4. Check the power budget: Calculate the expected load on each DC rail and verify the manufacturer’s permitted simultaneous output ratings.
5. Separate power and signal wiring: Route power conductors separately from sensitive analog and communication wiring where practical to reduce electrical interference.
6. Check grounding and bonding: Follow the manufacturer’s rack grounding instructions and the applicable plant electrical standards.
7. Commission the rack: Measure the specified DC rails and verify voltage stability under the intended load before placing the connected control system into service.
