Honeywell TK-FXX102 – 10-Slot I/O Rack | Experion PKS / TPS FX Series
Engineering Background
The Honeywell TK-FXX102 is a 10-slot I/O rack designed for the Honeywell TotalPlant Solution (TPS) and Experion PKS distributed control system platforms. As a core structural component of the FX Series I/O subsystem, this rack provides the physical and electrical backplane infrastructure required to mount and interconnect field I/O modules, power conditioners, and communication interfaces in process-critical environments.
Product Positioning
Targeted at process automation engineers and MRO procurement teams, the TK-FXX102 is the preferred rack solution for brownfield DCS expansions, system redundancy upgrades, and spare-parts inventory programs in refining, petrochemical, power generation, and continuous manufacturing facilities. Konmask.com supplies both new-surplus and factory-refurbished units with full traceability documentation.

Engineering Advantages
- 10-slot capacity maximizes I/O density per rack unit, reducing cabinet footprint
- Passive backplane architecture eliminates active backplane failure modes, improving MTBF
- Hot-swap module support (with compatible I/O modules) enables maintenance without process shutdown
- Seamless integration with Honeywell Experion PKS C300/C200 controllers and TPS HPM nodes
- Standardized form factor simplifies spare-parts management across multi-rack DCS cabinets
- Wide thermal tolerance supports installation in non-air-conditioned auxiliary rooms
System Architecture & Signal Flow
In a typical Experion PKS or TPS FX Series cabinet, the TK-FXX102 rack is mounted vertically or horizontally within a 19-inch enclosure. Field wiring terminates at I/O termination assemblies (FTA/ITA), which connect via marshalling cables to I/O modules seated in the rack slots. The rack backplane distributes 24 VDC power and the FX Series serial communication bus to each module slot. The controller node (C300 or HPM) communicates with I/O modules via the Control Firewall Bus (CFB) or FTE Ethernet backbone, depending on system generation. Redundant power supply modules can occupy dedicated slots to ensure continuous operation during PSU maintenance.

Technical FAQ
Q: Is the TK-FXX102 compatible with both TPS and Experion PKS systems?
A: Yes. The FX Series rack is used across both TPS (legacy) and Experion PKS (current generation) platforms. Verify your I/O module part numbers to confirm slot compatibility.
Q: Can I mix analog and digital I/O modules in the same rack?
A: Yes, subject to Honeywell’s I/O module placement rules. Consult the Experion PKS I/O Module Installation Guide (document EP-DS-0003) for slot assignment constraints.
Q: Does the rack support redundant power supply modules?
A: Yes, when paired with compatible Honeywell FX Series power supply modules. Redundant PSU configuration is recommended for SIL-rated loops.
Q: What is the lead time for new-surplus units?
A: Typically 1–5 business days for in-stock units. Contact us for real-time availability.
Q: Do you provide export documentation for international shipments?
A: Yes. We provide commercial invoice, packing list, CoC, and ECCN classification documentation for all international orders.
