Foxboro FBM217 RH916XZ — 16-Channel Analog Input Module

Product Series: Foxboro I/A Series Fieldbus Module (FBM) — Analog Input

Product Introduction:
The FBM217 RH916XZ is a 16-channel analog input module of the FBM217 family with a distinct part number and revision code (RH916XZ). It provides 4–20 mA and 1–5 VDC input acquisition for 16 process measurement channels and is designed for deployment in Foxboro I/A Series DCS systems requiring high-density analog input coverage.

Description

Model Series: FBM217 — 16-Channel Analog Input

Part Number: RH916XZ

Technical Specifications:

  • Channel Count16 channels
  • Input Signal Type: 4–20 mA (2-wire) or 1–5 VDC
  • Resolution16-bit A/D converter
  • Accuracy: ±0.15% of full scale
  • Conversion Time20 ms (all 16 channels)
  • Isolation: 1500 VDC channel-to-bus
  • Common Mode Rejection: >110 dB at 50/60 Hz
  • Operating Temperature0°C to 60°C (32°F to 140°F)
  • Power Consumption: < 4.0 W
  • Dimensions: Standard FBM form factor — 105mm x 130mm x 30mm

Structure Features:

  • 16 front-panel terminals in two rows of 8
  • Backplane bus connector with keyed alignment
  • Per-channel LEDs for signal/fault indication
  • DIP switch block for configuration

Function Features:

  • 16-channel simultaneous sampling at 20 ms scan rate
  • Burnout detection with configurable alarm thresholds
  • Input range auto-detection via software configuration
  • Channel grouping — supports two groups of 8 channels with independent scan rates

Working Principle:
The 16-bit sigma-delta A/D converter multiplexes across all 16 input channels. Each channel is sampled, converted, and the result is placed in the backplane communication buffer for the controller to read. Galvanic isolation (1500 VDC) separates the field wiring from the bus logic.

Advantage Highlights:

  • RH916XZ revision includes enhanced diagnostic reporting compared to earlier FBM217 revisions
  • 16 channels in one slot — maximizes backplane efficiency
  • Dual-group scanning allows different update rates for different channel sets
  • Full backward compatibility with P0914TR and P0916PW in the same chassis

Applicable Industries:

  • Large Process Plants
  • Refineries
  • Chemical Manufacturing
  • Power Plants

Installation Requirements:

  • Must be installed on FBM207B (16-terminal base)
  • Use 24 AWG to 18 AWG shielded twisted-pair cable for all inputs
  • Ensure loop power (24 VDC) is provided externally for 4–20 mA transmitters

Usage Notes:

  • RH916XZ is a specific revision — verify compatibility with the I/A Series controller firmware version
  • Do not substitute with other FBM217 part numbers without updating the DCS configuration database
  • Calibrate all 16 channels using Foxboro Calibration Utility before placing in service
