Product Overview

The Foxboro FBM206 (Part Number: P0916CQ) serves as a high-performance pulse interface within the I/A Series Distributed Control System (DCS). This module accepts high-frequency signals from field devices such as turbine meters, vortex meters, and magnetic pickups. By converting these raw pulses into precise digital data, it enables critical applications like custody transfer, batching, and high-speed flow monitoring. We provide this unit as 100% Brand New original equipment, ensuring the highest level of signal integrity for your process automation.

Technical Specifications

Engineering Advantages

• High-Frequency Precision: The FBM206 processes pulse signals up to 25 kHz per channel. This high bandwidth allows for extremely accurate totalization in high-velocity flow applications where standard I/O modules fail to capture rapid transitions.

• Onboard Signal Processing: The module performs local totalization and scaling calculations directly. By shifting these tasks from the main controller to the FBM, the system maintains accurate counts even during temporary communication interruptions with the workstation.

• Superior Noise Immunity: Full galvanic isolation between channels prevents ground loops from corrupting the signal. This is critical in large plants where potential differences between field grounding points often cause data errors.

• Corrosive Environment Resilience: With an ISA Class G3 rating, the P0916CQ hardware withstands atmospheric contaminants and harsh chemical vapors. This makes it the preferred choice for offshore platforms and refinery applications.

• Live Maintenance Capability: The hot-swappable design allows engineers to replace modules on a powered modular baseplate. You can perform hardware updates or repairs without disconnecting field wiring or interrupting the process loop.

FAQs

• What is the difference between the FBM206 and standard analog input modules?

  Unlike analog modules that measure current (4-20mA), the FBM206 counts discrete pulses. This makes it specifically compatible with turbine and vortex meters that output frequency-based data for high-precision flow measurement.

• Does the FBM206 support redundant communication?

  Yes. The module interfaces directly with the redundant 2 Mbps Foxboro fieldbus, ensuring that the control system maintains data visibility even if one fieldbus cable sustains damage.

• Can I use this module for custody transfer?

  Absolutely. The ±0.01% accuracy rating and high-speed processing capabilities meet the rigorous standards required for fiscal metering and custody transfer of oil and gas.

• Is the input voltage range adjustable?

  Yes, the input voltage is configurable between 7 and 27 V DC, allowing the module to interface with a wide variety of field sensors and magnetic pickups without additional signal conditioning hardware.
