Product Description
Foxboro P0931NC Invensys I/A Series Compression Termination Assembly
Product Overview
- The Foxboro P0931NC is a Compression Termination Assembly from the Invensys I/A Series (now part of Schneider Electric's EcoStruxure Foxboro DCS). This assembly is designed to provide a reliable and secure connection between field wiring and I/A Series Fieldbus Modules (FBMs), particularly for analog, discrete, HART, or temperature signal applications. It is used in industrial automation applications, including oil and gas, chemical processing, and power generation, to facilitate field device integration with the I/A Series control system.
