FOXBORO FBM202 P0926EQ – Multi‑channel 4–20 mA Analog Input Module for I/A Series Systems

The FOXBORO FBM202 P0926EQ is an I/A Series FBM200‑family analog input module, typically used to bring 4–20 mA process signals from transmitters into the control system with stable, low‑noise conversion. It fits the standard FBM baseplate/terminal assembly architecture and is a straightforward drop‑in when you’re expanding or maintaining existing Foxboro installations. One thing I appreciate is how predictable it is during maintenance — in many cases you can swap the module and have the channel diagnostics back online in minutes, without reworking the cabinet.

Company’s Order Placement Process and Guarantees

• Warranty: 365 days
• Lead time: In‑stock items typically ship in 1 week; no more than one month at the latest
• Payment: 50% advance payment, full payment before delivery
• Courier options: FedEx, UPS, DHL

Key Features

• Multi‑channel 4–20 mA inputs – Typically 8 channels for compact, high‑density signal acquisition in one module.
• Stable, low‑noise conversion – Designed for process transmitters; you get consistent readings even on longer cable runs.
• Channel isolation – In most cases channels are isolated from each other and from the backplane, which helps avoid ground loops and cross‑talk.
• FBM200 standard form factor – Fits existing Foxboro FBM baseplates and field termination assemblies (FTA), which keeps retrofit work minimal.
• Diagnostics and status LEDs – Quick visual checks during commissioning or fault tracing; you can spot bad loops faster.
• Smart‑device friendliness – Many FBM202 variants support HART pass‑through on the 4–20 mA loop; P0926EQ is commonly used in such setups (please confirm during ordering).

Technical Specifications

Application Fields

From my experience, the FBM202 fits best where you need reliable current loops and straightforward maintenance:

• Oil & Gas: Pressure, flow, and temperature transmitters on skids and wellhead panels
• Chemicals & Petrochem: Reactor and utility loops where 4–20 mA is the site standard
• Power & Utilities: Boiler and balance‑of‑plant analog instrumentation
• Water & Wastewater: Distributed pump stations and treatment process monitoring
• Pharma & Food: Clean utilities and HTF loops where signal integrity matters

Advantages & Value

• Reliability – The FBM200 platform is known for robust operation; downtime due to the I/O module itself is rare.
• Compatibility – Works within existing Foxboro I/A cabinets and wiring practices, so you avoid re‑marshalling costs.
• Serviceability – You might notice how quickly a technician can change one out; the baseplate/FTA approach keeps loops intact.
• Lifecycle savings – Standardized spares across multiple cabinets reduce inventory and training overhead.
• Technical backing – Support for loop diagnostics and, on many variants, HART tools helps maintenance teams verify devices faster.

Installation & Maintenance

• Cabinet & Mounting – Install on an FBM200 baseplate mounted to a rigid panel in a ventilated enclosure. Allow front access for module replacement.
• Power & Grounding – Feed the baseplate with clean 24 VDC and maintain a solid cabinet ground. Keep shield drains consistent with site standards.
• Wiring – Use twisted‑pair for 4–20 mA loops; segregate from high‑voltage runs. If HART is used, keep the loop impedance in the recommended range (typically around 250 Ω).
• Safety – De‑energize circuits before handling field wiring. Follow site lockout/tagout procedures.
• Routine care – Periodic loop checks and transmitter calibration; dust the module front with a dry cloth; confirm firmware compatibility when adding or replacing modules.

Quality & Certifications

• Conforms to typical industrial EMC and safety standards for the FBM200 family
• CE marking; UL/cUL compliance in many deployments; RoHS depends on production vintage
• Manufacturer quality system aligned with ISO practices
• Sales warranty: 365 days from shipment

Suggested Supporting Components

• FOXBORO FBM204 – 4–20 mA analog output module; commonly paired with FBM202 for closed‑loop control.
• FOXBORO FBM207 – 4–20 mA analog input with HART pass‑through (variant); suited for smart transmitters if you need extended diagnostics.
• FBM200 Baseplate (8‑ or 16‑position) – Panel‑mounted baseplate providing backplane power/communications to FBM modules.
• Field Termination Assemblies (FTA) – Matching terminal assemblies for clean marshalling; barrier/non‑barrier versions depending on the area classification.
