P0916CQ Foxboro FBM206 8-Channel Isolated Pulse Card

Product Overview

The Foxboro FBM206 (Part Number: P0916CQ) functions as a high-precision pulse input interface for Foxboro I/A Series and Evo™ distributed control systems. This module captures high-speed frequency signals from field instruments such as turbine meters, vortex flowmeters, and magnetic pickups. By providing 8 fully isolated channels, the FBM206 converts raw pulse data into accurate flow rates and totalization values for real-time process control. We supply this unit as 100% Brand New and Original, ensuring your critical metering loops operate with factory-certified accuracy and zero signal drift.

Technical Specifications

Engineering Advantages

• High-Speed Signal Integrity: The FBM206 processes high-frequency signals up to 25 kHz per channel. This high-bandwidth capability allows the module to interface with modern high-resolution flowmeters, ensuring the control system captures every pulse for precise batching and custody transfer applications.

• Superior Galvanic Isolation: Every input channel features dedicated galvanic isolation. This architecture eliminates ground loops and protects the DCS backplane from field-side electrical noise or surges, which is critical when sensors reside in distant or electrically "noisy" areas.

• Local Totalization & Scaling: The module performs pulse rate calculations and scaling locally before transmitting data to the control processor. This onboard processing reduces the computational load on the main controller and ensures that totalization continues even during momentary communication interruptions.

• Ruggedized for Harsh Sectors: Carrying an ISA Class G3 rating, the FBM206 withstands corrosive atmospheres, including high concentrations of chemical vapors and moisture. This makes it suitable for offshore platforms, chemical plants, and refineries where standard electronics often fail.

• Hot-Swappable Maintenance: The module supports hot-swapping on the system baseplate. Maintenance teams replace units without disconnecting field wiring or powering down the rack, significantly reducing Mean Time to Repair (MTTR) and preventing process downtime.

FAQs

What types of sensors can I connect to the FBM206?

The FBM206 interfaces with 2-wire pulse sensors, including turbine meters, vortex flowmeters, and dry contact switches. It supports a wide input voltage range (7 to 27 V DC), allowing it to work with a diverse array of manufacturer-specific pulse outputs.

Does this module guarantee "no missed pulses"?

Yes. As long as the input signal remains within the 10 Hz to 25 kHz frequency range and the specified voltage thresholds, the high-resolution internal processing hardware captures every pulse for accurate totalization.

Can the FBM206 be used in a redundant configuration?

The module communicates over the redundant Foxboro Fieldbus (Dual Path A/B), providing high availability at the communication level. For application-level redundancy, you can configure paired modules depending on your specific DCS strategy.

How do I confirm this unit is 100% Brand New?

Every Foxboro FBM206 we provide is 100% brand new and original factory stock. Each unit ships in original packaging with a verified serial number and undergoes full factory-level diagnostics to meet original manufacturer specifications.
