Foxboro FBM204 P0914SY Channel Isolated I/O Module

Description

The FBM204 module is a key component of the Foxboro Distributed Control System (DCS). It is designed to interface electrical signals from field sensors to the control system, ensuring seamless integration and control. The module features four 20 mA DC analog input channels and four 20 mA DC analog output channels, each galvanically isolated to maintain signal integrity and minimize electrical noise.

Features

• Analog Input Channels:
  • Four 20 mA DC analog input channels.
  • Accepts inputs from a 4 to 20 mA transmitter or a self-powered 20 mA source.
• Analog Output Channels:
  • Four 20 mA DC analog output channels.
  • Capable of driving external loads and producing 0 to 20 mA output.
• Galvanic Isolation:Each input and output channel is isolated from the others and from the ground.
• Rugged Design:Suitable for Class G3 (harsh) environments, ensuring reliable operation under challenging conditions.
• Analog I/O Application Program:Provides conversion time and configurable options for Rate of Change Limits, offering flexibility in data handling.
• High Accuracy:Utilizes sigma-delta data conversions for each channel to achieve high accuracy.
• Termination Assemblies (TAs):Facilitates connection of field wiring to the module, either locally or remotely.
• HART Compatibility:Electrically compatible with standard HART communication protocols, allowing integration with HART-enabled devices.
• Visual Indicators:LEDs provide status indications of module functions for easy monitoring.
• Fieldbus Communication:Interfaces with a 2 Mbps module fieldbus used by the FBMs, ensuring robust communication.

Specifications

• Input/Output Range: 0 to 20 mA DC
• Signal Conversion: Required to interface the electrical input/output signals from the field sensors to the optionally redundant fieldbus.
• Analog Output Fail-Safe Fallback Data: Configurable on a per-channel basis.
• Environmental Conditions: Designed to withstand harsh industrial environments.
• Dimensions and Weight:
  • Not specified in the provided information, typically conforms to standard module sizes within the Foxboro DCS.
