The Foxboro FBMSLT serves as a high-performance Fieldbus communication and analog output interface within the Invensys I/A Series Distributed Control System (DCS). This module bridges the gap between the control network and field devices by providing eight precise 4–20 mA output channels alongside robust FOUNDATION Fieldbus H1 connectivity. We provide this unit as 100% brand new, original factory stock to ensure maximum uptime in mission-critical environments.

Fault-Tolerant Reliability: The FBMSLT supports a dual-processor configuration. This architecture eliminates single points of failure, maintaining continuous process control even if one processor fails.
Seamless Maintenance: The hot-swappable design allows technicians to replace modules without powering down the system. This significantly reduces Mean Time to Repair (MTTR) in continuous processing plants.
Signal Integrity: Independent power regulation and electrical isolation for every channel prevent ground loops and protect the internal logic from field-side electrical surges.
Advanced Diagnostics: When paired with the optional F809F-Plus module, the system delivers real-time health monitoring of the Fieldbus physical layer, identifying cable degradation or noise issues before they cause unplanned shutdowns.
Simplified Field Integration: By combining traditional 4-20 mA outputs with modern Fieldbus H1 protocols, this module allows engineers to manage hybrid field device environments from a single slot.
Is this FBMSLT module supplied in original packaging?Yes. We supply only 100% Brand New original Foxboro Invensys units. Each module ships in its factory-sealed anti-static packaging to guarantee integrity and performance.
Does the module support redundant power supplies?Absolutely. The FBMSLT accepts 24 VDC redundant power inputs, ensuring the module remains operational even if one primary power source fails.
Can I use this module to replace older I/A Series output cards?The FBMSLT is designed for the I/A Series ecosystem. However, you should verify your specific system software version and baseplate compatibility. Our technical team can assist with firmware compatibility checks.
What is the primary benefit of the "Independent Current Limiting" feature?It ensures that a short circuit or fault on one specific field device channel does not affect the operation or power stability of the remaining seven channels, localized failure remains isolated.
Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
Finding brand new, original modules is critical for our safety. This team delivers factory-fresh components with full certification. Their commitment to only selling new products makes them our most trusted partner.
We have sourced Honeywell and Schneider parts here for two years. Every shipment arrives well-packaged with original factory seals intact. Clear communication and the best lead times in the industry.
