Product Overview
The 761CNA-AT is a microprocessor-based digital single-station controller designed for localized process control applications. As part of the Single Station Micro Plus series, it supports advanced control algorithms and an intuitive operator interface for regulating flow, temperature, pressure, and other continuous process variables.
Configured for 120 VAC power environments, the 761CNA-AT integrates seamlessly into existing Foxboro control infrastructures. Its form factor enables direct retrofit into legacy 760/761 series installations, allowing system upgrades without extensive rewiring or panel modification.
