FOXBORO FBM216 P0922VV HART Communication Redundant Input Interface Module

The FBM216 is a high-performance, redundant input interface module designed for processing analog signals and HART digital communication signals in industrial automation systems. Its compact, rugged design ensures reliability in harsh environments, making it an ideal solution for mission-critical applications.

Key Features

Channel Versatility:
- Supports 8 input channels, each configurable for:
  - Standard 4 to 20 mA analog sensor signals
  - HART Frequency Shift Keying (FSK) digital signals superimposed on the analog signal.
Redundancy:
- A module pair offers redundancy at the Fieldbus Module (FBM) level, ensuring uninterrupted operation.
High Accuracy:
- Incorporates Sigma-Delta converters for accurate signal processing, with updates every 100 milliseconds.
HART Communication:
- Each channel has a dedicated FSK modem for bi-directional communication with HART devices.
- Supports universal, common practice, and device-specific HART commands.
Galvanic Isolation:
- Channels are group-isolated from ground and module logic for safety and noise immunity.
Compact Design:
- Lightweight, robust aluminum enclosure suitable for Class G3 (harsh) environments.
Power Options:
- Integrated isolated power supply or optional external power supply with Cable Balun module for channel crosstalk prevention.
Easy Termination:
- Termination Assemblies (TAs) allow local or remote connection of field wiring.
