Each unit is function-tested before dispatch and packed for industrial transit.
Analog input for process loops: Built for standard 4–20 mA acquisition, commonly used with transmitters across flow, pressure, level, and temperature.
Backplane integration: Interfaces directly to the Foxboro I/A Series system backplane, keeping wiring neat and commissioning straightforward.
Channel isolation and noise rejection: Designed for stable readings in electrically noisy panels; helps reduce drift and ground loop issues.
Diagnostic indicators: Front status LEDs (typical on H-series) provide quick visual checks—handy during start-up and maintenance.
Industry-friendly form factor: Compact module footprint to fit existing Foxboro carriers/chassis without rework.
HART pass-through on applicable variants: In many cases, H92 family variants support HART data over 4–20 mA; confirm by sub-revision if you plan asset management integration.
| Brand / Model | Foxboro H92 H92A049E0700 Analog Input Module |
| HS Code | 8537.10 (Boards, panels, consoles for electric control, ≤1000 V) |
| Power Requirements | Backplane powered; nominal 24 VDC distribution typical within I/A Series chassis |
| Signal Input Types | Analog current inputs (commonly 4–20 mA). Voltage input variants exist within the H92 family; verify by sub-variant. |
| Signal Output Types | Backplane data to controller (no field analog output on this module) |
| Communication Interfaces | I/A Series system backplane interface; HART pass-through on applicable H92 variants |
| Operating Temperature | Typically 0 to +50°C (32 to 122°F); install in ventilated cabinet |
| Dimensions & Weight | Compact H-series module form factor for Foxboro carriers; designed for dense cabinet layouts |
| Installation Method | Mounts in Foxboro I/A Series chassis/carrier; field terminations via the associated terminal assembly |
This module fits where dependable analog data is a must: refining, petrochemicals, gas processing, power generation (balance-of-plant loops), pharmaceuticals (utility skids), food & beverage (CIP/SIP utilities), water/wastewater (lift stations, chlorination), and pulp & paper. A maintenance lead told me they picked the H92 series simply because it “just reads clean 4–20 mA without surprises,” especially on long runs with shielded cable.
Reliability: Stable acquisition and solid isolation help reduce nuisance trips and false alarms in noisy environments.
Compatibility: Works within Foxboro I/A Series architecture—no need to re-qualify third-party cards or adapters.
Lifecycle cost: Minimizes engineering time for retrofits; typically reuses existing carriers and termination assemblies.
Supportability: Diagnostic indicators and straightforward loop checks speed up troubleshooting and routine PMs.
Panel environment: Install in a clean, ventilated cabinet; keep ambient within the typical 0–50°C range and humidity under condensation levels.
Wiring practices: Use shielded twisted-pair for 4–20 mA; terminate shields at a single point. Separate high-voltage and analog signal runs.
Grounding & isolation: Avoid ground loops; check loop power supplies and reference points before commissioning.
Commissioning: Verify each loop with a calibrator; confirm span and scale in the controller faceplate prior to handover.
Routine maintenance: Annual loop checks are usually enough. Dust the module fronts and carriers; review diagnostics for any channel quality flags.
Firmware/config: If your system uses module-specific firmware, align revisions across redundant cabinets to keep behavior consistent.
Spares strategy: Keep at least one spare H92 module per cabinet section; it shortens recovery time during unplanned outages.
CE compliant
UL/cUL recognized (typical for Foxboro I/A Series modules)
RoHS alignment on applicable vintages
Manufacturer’s warranty available; sales warranty: 365 days
For planning, pair the H92 with the appropriate Foxboro I/A Series carrier/chassis and the matching terminal assembly (TA) for field wiring. Many plants also keep spare backplane power supplies and a handheld loop calibrator for quick validation. If HART diagnostics are needed, confirm that your H92 sub-variant supports HART pass-through and that your controller/asset management software is enabled for it.
Note: Specifications can vary slightly by H92 sub-revision. If you have a P/N label or a cabinet photo, share it and I’ll verify channel type, isolation rating, and any HART capability on your exact unit.
