  • No Firmware for Chassis: The Honeywell TC-FXX072 is a passive hardware backplane and contains no firmware or software. It does not require any updates.
  • Firmware for Installed Modules: Firmware updates are performed only on the modules installed within the chassis (e.g., C200E controller, CNI communication modules) via the ControlNet network using Honeywell NTOOLS.
  • Gateway-Only Firmware Loading: For Rail I/O modules (RIOM-A), only the ControlNet Gateway supports firmware loads through NTOOLS; other modules in the chassis are not loadable.
  • Update Process: ControlNet firmware updates require the appropriate engineering tools (NTOOLS) and are managed online or offline per Honeywell standard procedures.

  • Environmental Compliance: Meets CE EMC Directive (89/336/EEC) per EN 50081-2 (Emissions) and EN 50082-2 (Immunity) for industrial environments.
  • Corrosion Protection: The TK-FXX072 variant offers conformal coating tested to G3 level (harsh) per ISA-S71.04-1985, protecting electronics in corrosive gas atmospheres.
  • RIUP Restriction: Removal/Insertion Under Power is permitted only in ordinary, non-hazardous locations; strictly prohibited when the chassis is installed in a Class I, Division 2 hazardous location to maintain safety.
Description
Honeywell TC-FXX072 is a fundamental hardware component of the Honeywell Experion LS distributed control system, specifically belonging to the Chassis Input/Output Module Series A (CIOM-A) family. Its primary function is to serve as a physical and electrical backbone, accepting up to seven single-wide or double-wide Series-A modules. These modules can include analog or discrete I/O, the C200E control processor, redundancy modules (RM), ControlNet Interface (CNI) cards, serial interface modules, and other specialty cards. The chassis itself is passive and requires connection to a separate, compatible power supply module, which mounts on its left side without occupying a module slot.

Honeywell TC-FXX072 is available in two variants: the standard TC-FXX072 (uncoated) and the TK-FXX072 (conformal coated). The coated version is specifically designed for moderate (G2) to harsh (G3) corrosive environments, as defined by ANSI/ISA-S71.04-1985, providing critical protection against airborne contaminants. The chassis supports a wide operating temperature range from 0°C to 60°C and is certified for use in ordinary and Class I, Division 2 hazardous locations (Groups A, B, C, D), making it suitable for both general industrial and potentially explosive atmospheres when properly configured with appropriate power supplies and modules.

For installation, Honeywell TC-FXX072 requires a minimum enclosure depth of 20.3 cm and specific spacing from cabinet walls and other chassis for proper ventilation. It is designed for panel mounting. Power is supplied via either a non-redundant power supply (e.g., TC-FPCXX2 series) or a redundant power system (using two TC-RPCXX1 supplies and a TC-RPSCA2 chassis adaptor). The redundant configuration provides current sharing, error detection, and failure annunciation, ensuring high system availability for critical control applications.

Technical notes
Honeywell TC-FXX072 is a passive backplane; it requires an external power supply module (non-redundant or redundant) and does not generate any voltages itself.Honeywell TC-FXX072 supports RIUP (hot-swap) of I/O modules only in non-hazardous, ordinary locations; RIUP is not permitted in Class I, Division 2 hazardous areas.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How many I/O modules can I install in one Honeywell TC-FXX072?
The Honeywell TC-FXX072 has seven physical slots. You can install up to seven single-wide modules or a combination of single-wide and double-wide modules (each double-wide occupies two slots).
How do I monitor the health of my Honeywell TC-FXX072 chassis?
The chassis itself is passive and provides no direct diagnostics. System monitoring is done through the installed power supplies (via fault relays and LEDs) and the ControlNet network using Honeywell NTOOLS, which monitors communication status of modules installed in the TC-FXX072.
Can I replace modules while the system is running on Honeywell TC-FXX072?
Yes, but with restrictions. Removal/Insertion Under Power (RIUP) is permitted for the Honeywell TC-FXX072 only when installed in ordinary, non-hazardous locations. RIUP is NOT permitted in Class I, Division 2 hazardous areas.
What is the difference between TC-FXX072 and TK-FXX072?
The TC-FXX072 is the standard version. The TK-FXX072 has a conformal coating applied, making it suitable for moderate (G2) to harsh (G3) corrosive environments according to ISA-S71.04-1985.
