General Description

• Manufacturer: Schneider Electric (Foxboro)
• Model Number: FBM201 (Part Number: RH914SQ, supersedes P0914SQ)
• Product Type: Analog Input Module
• Function: Provides eight analog input channels for 0 to 20 mA dc signals from analog sensors (e.g., 4 to 20 mA transmitters or self-powered 20 mA sources).
• System Compatibility:
  • Interfaces with the Foxboro Evo Process Automation System via a redundant 2 Mbps module Fieldbus.
  • Electrically compatible with standard HART signals.

• Input Range: 0 to 20 mA dc
• Input Channel Impedance: 61.5 Ω nominal
• Analog Accuracy (Includes Linearity): ±0.03% of span
• Accuracy Temperature Coefficient: ±50 ppm/°C
• Input Signal A/D Conversion: Each channel uses an independent Sigma-Delta converter, providing a new reading every 25 ms

• Input Channel Isolation:
  • Each channel is galvanically isolated from other channels and ground.
  • Withstands 600 V ac applied for one minute between any channel and ground or between channels (not intended for permanent connection to such voltages).
• Loop Power Supply Protection:
  • Each channel is galvanically isolated, current limited, and voltage regulated.
  • Analog inputs limited to <30 mA; in case of a shorted current limit circuit, current is limited to ~100 mA.
• Field Device Cabling Distance:
  • Maximum distance depends on compliance voltage (22.8 V dc), wire resistance, and voltage drop at the field device.
• Visual Indicators: LEDs on the front of the module indicate Fieldbus Module status (power, communication, etc.).
• Construction: Rugged extruded aluminum exterior for physical protection.
