FOXBORO RH916TA – 16‑slot rack housing with termination assembly for I/A Series FBM I/O

The FOXBORO RH916TA is, in many cases, the go‑to 16‑slot chassis for deploying I/A Series FBM I/O with clean field terminations. It combines a robust rack backplane with an integrated termination assembly (TA), so you can mount FBMs and land field wiring in a tidy, serviceable layout. One thing I appreciate is how it keeps redundancy simple—power and Fieldbus are arranged the way maintenance teams expect, and swapping an FBM typically takes minutes, not hours.

Company’s Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery time: 1 week if in stock; no more than one month at the latest
• Payment: 50% advance payment; full payment before delivery
• Express options: FedEx, UPS, DHL

Key Features

• 16‑slot FBM capacity – Supports a full set of I/A Series FBM2xx modules for analog, discrete, HART, and specialty signals.
• Integrated termination assembly (TA) – Field wiring lands directly on the TA, keeping loops organized and reducing panel depth.
• Redundant backplane power – Typically accepts dual 24 VDC feeds for higher availability; module replacement without powering down in most cases.
• Redundant Module Fieldbus – Backplane communications designed for Foxboro’s I/A Series architecture, easing expansion and migration.
• Serviceable layout – Clear labeling and front access help technicians trace, test, and replace FBMs quickly.
• Industrial‑grade build – Suited for control cabinets in demanding environments like refining, chemicals, and power plants.
• Compatibility – Works with common FBMs such as FBM201/203 (analog input), FBM207 (discrete), FBM214 (analog output), FBM218 (HART), and similar, depending on system design.

Technical Specifications

Application Fields

From my experience, the RH916TA shows up most in continuous process industries where uptime matters:

• Refining and petrochemical units (FCC, hydrocrackers, utilities)
• Specialty and bulk chemicals, polymers
• Power generation and cogeneration balance‑of‑plant
• Water and wastewater treatment skids
• Pulp & paper and food process lines migrating to I/A Series

Advantages & Value

• Reliability – Redundant power and Fieldbus reduce single‑point failures; hot‑swap FBM service typically supported.
• Compatibility – Broad support for FBM2xx cards keeps spares common and simplifies lifecycle planning.
• Panel efficiency – Integrated TA minimizes extra terminal strips and cuts cabinet depth, which often saves enclosure costs.
• Maintenance speed – Clear front access to both FBMs and terminations helps reduce MTTR during outages.
• Scalable – 16 slots allow phased expansions without re‑paneling the entire bay.

Installation & Maintenance

• Cabinet & mounting – Mount in a rigid control cabinet or rack panel; keep 50–75 mm clearance for airflow. Avoid heat sources and vibration when feasible.
• Power & grounding – Provide clean, redundant 24 VDC feeds with proper earthing. Follow Foxboro grounding and shielding practices for low‑noise analog loops.
• Wiring – Land field cables on the TA; segregate analog, discrete, and high‑noise lines. Use ferrules and label both wire ends to simplify turnover.
• ESD & handling – Treat FBMs as ESD‑sensitive; insert/remove on de‑energized loops when required by procedure.
• Routine care – Periodically check terminal torque, inspect for dust, and clean with dry air. Review controller/FBM firmware release notes before updates.
• Spares strategy – Keep at least one spare RH916TA per cabinet row in critical areas, plus spare power feeds. A maintenance lead told us they cut troubleshooting time by half after standardizing on this approach.

Quality & Certifications

• Typically CE and UL/cUL compliant; RoHS status depends on exact manufacturing lot and region
• Designed for industrial environments aligned with IEC/EN control cabinet practices
• Manufacturer’s standard warranty is commonly 12 months; our supplied units carry a 365‑day warranty

Supporting Components You May Consider

• FBMs (e.g., FBM201/203/214/218/223) to match required analog, discrete, and HART signals
• Redundant 24 VDC power supplies and distribution modules sized for full 16‑slot load
• Shielded field cabling and marshalling accessories for clean loop segregation
• Controller/FCM components for I/A Series system interface and redundancy

If you share your signal count and any redundancy preferences, we can map the RH916TA slotting and TA wiring plan so commissioning goes smoothly.
