Product Description
Foxboro MZ-77E500B/AM Invensys I/A Series Pneumatic Actuator
Product Overview
- The Foxboro MZ-77E500B/AM is a Pneumatic Actuator from the Invensys I/A Series (now part of Schneider Electric's EcoStruxure Foxboro DCS). This actuator is designed to control the position of valves or dampers in industrial processes, converting pneumatic signals into mechanical motion. It is used in applications such as oil and gas, chemical processing, and power generation to regulate flow, pressure, or other process variables. The AM suffix likely indicates a specific configuration, such as an accessory or mounting option.
