FBM201D
Product Description
The Foxboro FBM201D is a specialized Fieldbus Module (FBM) within the highly robust Foxboro I/A Series Distributed Control System (DCS). It serves as a crucial interface between process field sensors and the central control system.
Specifically, the FBM201D is an 8-channel, channel-isolated analog input module designed to accept 0 to 10 VDC input signals from various analog sensors in the field. Its “channel-isolated” feature means that each input channel is galvanically isolated from other channels and from ground, which significantly enhances noise immunity and protects against ground loops, crucial for reliable measurement in industrial environments.
This module is designed for accuracy, incorporating sigma-delta data conversion on a per-channel basis for high-resolution and precise signal conversion. It plays a vital role in data acquisition, converting analog sensor readings (like voltage signals from position sensors, level transmitters, etc.) into digital data that the DCS can process for monitoring, control, and automation tasks. The FBMs are known for their rugged, extruded aluminum exterior, making them suitable for harsh industrial environments (Class G3 as defined in ISA Standard S71.04).
