Foxboro 118302021 Industrial Control PC Board Module

The Foxboro 118302021 is a compact printed circuit board module designed for use in industrial control systems, particularly within the Foxboro I/A Series for process automation. This module features a simple analog circuit layout with through-hole components including capacitors, resistors, transistors, and an adjustable potentiometer, making it suitable for signal conditioning, amplification, or basic control functions in environments like chemical plants, oil refineries, and manufacturing facilities. Key benefits include high reliability in harsh conditions, ease of plug-in installation, and compatibility with legacy systems, offering cost-effective maintenance for older setups. However, as a vintage component (likely from the 1980s-1990s), it may face drawbacks such as limited availability of spares, lack of modern digital interfaces, and potential obsolescence compared to contemporary modules with IoT integration and higher processing speeds. Advantages over similar products include its robust, field-proven design that withstands electromagnetic interference better than some entry-level alternatives. Based on image analysis, the board appears used but in good condition, with no visible damage, slight dust accumulation, and intact components. No serial number is clearly visible on the faceplate, and there are no apparent parent/child assets like attached sensors. For resources, refer to Foxboro I/A Series documentation; a datasheet summary is available via Schneider Electric's site (e.g., search for 'Foxboro I/A Series modules' on https://www.se.com). Estimated market price for used units ranges from $50-150 USD based on recent surplus sales data from sites like eBay and industrial resellers.
