Honeywell TK-FXX102 C200 10-Slot Chassis Rack

Description

The TK-FXX102 is a rugged, heavy-duty structural hardware component configured as a 10-Slot Rack (Chassis) within the Honeywell C200 and Experion distributed control system (DCS) architectures. This chassis serves as the central physical and electrical backbone for the C200 system, providing 10 dedicated hardware slots to house control processors, power supplies, redundancy modules, communication gateways, and high-density I/O modules (CIOM-A). Built with an integrated multi-tier backplane printed circuit board, it provides deterministic data routing paths and stabilized DC power distribution lines across all inserted modules. Its robust mechanical frame is designed for standard panel or enclosure mounting, ensuring safe electrical isolation, structural alignment, and resistance to harsh environmental stresses in critical process plant installations.

Features

• 10 high-integrity module slots providing uniform layout flexibility and expansion capabilities.
• Integrated passive backplane layout ensuring reliable, deterministic cross-module communications.
• Rigid industrial-grade metal casing designed to prevent twisting and misalignment under mechanical stress.
• Dual-point grounding pathways engineered to secure logic-tier electronics against high-frequency transients.
• Standardized pre-drilled mounting tabs for direct fastening into equipment control cabinets.

Applications

• Centralized housing for primary and redundant C200 process controller setups.
• Local and remote I/O chassis grouping for distributed plant data acquisition loops.
• System infrastructure grouping inside chemical, petroleum, and pharmaceutical control rooms.
• Main chassis backplane installation within power generation and utility automation panels.

Installation Guidelines

Panel Mounting and Dimensions

Fix the chassis rack inside the industrial enclosure using standard heavy-duty fasteners through all pre-drilled flange holes. Confirm the mounting plane is completely flat and level to prevent any tortional twisting of the frame, which can stress the backplane motherboard or lead to loose module guide tracking.

Grounding and Shielding

Securely attach a thick, low-impedance copper ground strap from the designated grounding studs on the chassis frame directly to the master instrumentation earth bus bar. Proper grounding is critical to guarantee electrical shield continuity and protect backplane logic lines from external electromagnetic field interference.

Cooling and Ventilation

Leave a minimum unobstructed clearance of at least 5 to 10 cm above and below the chassis rack assembly inside the enclosure panel. This safety margin facilitates proper natural convection or forced-air cooling, preventing trapped hot air from raising the internal temperatures of the operating modules.

Module Insertion and Alignment

Before inserting any control module, inspect the slot tracks and backplane pin connectors to confirm they are clear of dirt or debris. Slide the module cards smoothly along the upper and lower plastic tracks until they are fully seated into the rear backplane receptacles, then hand-tighten the integrated faceplate retaining screws.

FAQ

What is the core function of the 10-slot rack assembly?

It provides the physical framing, guide slots, and electrical backplane connectivity required to house and link C200 system modules.

Can a standard power supply module be mounted directly inside this chassis?

Yes, specific slots on the backplane are designed to accept and route power directly from compatible C200 power supply units.

Is this rack assembly compatible with modern Experion I/O modules?

Yes, it features the native CIOM-A form factor built explicitly for C200 controllers and associated chassis-based I/O components.

What is the gross package weight when boxed for bulk delivery?

The estimated shipping weight of the chassis unit within its protective transport carton is rated at 2.5 Kg.

Does this chassis incorporate active cooling fans on the backplane?

No, it is a passive mechanical rack that relies on proper panel ventilation spacing and ambient convection air patterns.

How is the module address or slot number determined inside this rack?

The slot positions are numbered sequentially from left to right along the backplane, and the system software references these physical locations.

Can multiple chassis racks be linked together in a single system panel?

Yes, multiple racks can be networked using compatible ControlNet interface modules or specialized link cables to expand I/O capacity.

What precautions should be taken concerning backplane connection pins during installation?

Never force a module into a slot if resistance is encountered; inspect for bent alignment pins or tracking block obstacles first.

Are special mounting brackets needed to fit this unit into standard industrial cabinets?

The rack frame is engineered with built-in side flanges that allow direct bolting to standard layout panels without extra hardware kits.

How should static electricity be managed when interacting with an unpopulated rack?

Always wear an active, grounded anti-static wrist strap before touching backplane connectors or inserting circuit cards to avoid ESD damage.
