Foxboro 1040052B Fieldbus Module

Product Description

The Foxboro 1040052B is a high-performance Fieldbus Module (FBM) for the I/A Series distributed control system (DCS). It is engineered to capture analog signals from field transmitters and sensors, delivering precise data to control processors for stable and reliable process automation.

Built with a compact, modular design, the 1040052B fits easily into control cabinets while maintaining durability in demanding industrial conditions. It supports 8–16 analog input channels with 16-bit high-resolution measurement, ±0.1% span accuracy, and standard 4–20 mA current loops. Redundant 24 VDC power supply support and integrated over-voltage and short-circuit protection ensure continuous fault-tolerant operation.
