Description
Overview
The Foxboro BS811TH is a high-performance power supply module engineered for the Foxboro I/A Series Distributed Control System (DCS). It delivers stable, regulated 24 VDC power to Fieldbus Modules (FBMs), controllers, communication interfaces, and other critical DCS components. Designed for continuous operation, it features redundancy support, advanced protection mechanisms, and robust tolerance to industrial conditions.
Design and Functionality
The BS811TH provides reliable, uninterrupted power from a 120/240 VAC input with a high-capacity 10 A output. Its modular design supports dual-redundant operation and ensures secure integration within racks or cabinets. Industrial-grade protections against over-voltage, over-current, and thermal events make it ideal for mission-critical automation environments such as oil & gas, chemical processing, power generation, and water treatment.

Alternate Catalog Variant
Some suppliers list the BS811TH as a high-input analog module supporting signals such as:
-
Current: –40 to +40 mA
-
Voltage: 0 to 10 V, 4–20 mA
-
RTDs and Thermocouples
-
Accuracy: ±0.1% FS
-
Response Time: <2 s
-
Operating Temperature: –40°C to +80°C
This variant reflects alternate cataloging, but the primary and authoritative description identifies BS811TH as a power supply module.
