Product Overview

The Foxboro FBM218 (Part Number: P0922VW) provides a high-reliability interface for HART communication within the I/A Series Distributed Control System (DCS). This redundant output module drives eight isolated channels, allowing the control system to manage and communicate with intelligent field actuators, valves, and positioners. We supply this unit as 100% Brand New original factory stock, ensuring seamless integration with your existing Foxboro architecture and providing full support for HART versions 5, 6, and 7.

Technical Specifications

Engineering Advantages

• Redundant Path Assurance: The FBM218 communicates via a redundant 2 Mbps HDLC fieldbus. This architecture ensures that output signals to critical valves and actuators remain active even if a single communication path or Fieldbus Communication Module (FCM) fails.

• Superior Galvanic Isolation: Every channel utilizes both optical and transformer isolation. This dual-layer barrier protects the module logic and the entire DCS backplane from ground loops and field-side electrical surges up to 600 V AC.

• Intelligent Device Management: By supporting HART versions up to 7, the P0922VW allows the DCS to capture secondary variables and diagnostic data from field instruments. This visibility enables predictive maintenance and reduces physical field inspections.

• High Thermal Tolerance: The module operates reliably in temperatures up to +70°C (+158°F). This rugged rating permits installation in remote field enclosures where ambient temperatures often exceed the limits of standard office-grade electronics.

• Rapid Maintenance: The hot-swappable design allows technicians to replace the module without powering down the system or disturbing the field wiring. This capability minimizes process downtime during hardware upgrades or repairs.

FAQs

• Does the P0922VW support older HART instruments?

  Yes. The FBM218 maintains backward compatibility and supports HART instruments compliant with versions 5, 6, and 7 of the HART specifications.

• Is this a Brand New or Refurbished unit?

  We sell this Foxboro P0922VW as 100% Brand New original equipment. It comes in factory packaging to ensure it meets all OEM performance standards.

• What is the significance of the 600 V AC isolation?

  In heavy industrial environments, motor starts or lightning strikes can cause significant ground potential shifts. The 600 V AC isolation ensures that such faults do not travel from the field wiring into your sensitive control processors.

• How quickly can this module ship?

  Under normal conditions, we ship the P0922VW within 1 to 10 working days via premium carriers like DHL, FedEx, or UPS.
