Foxboro N0311GA Control Module

Product Description

The Foxboro N0311GA is a compact, high-performance control module designed for the Spectrum / Spec 200 DCS platform. It combines central processing, analog I/O, and digital I/O in a single rugged unit, effectively functioning as a PLC-class controller for complex automation tasks. Supporting IEC 61131‑3 programming standards—including Ladder Logic, Function Block Diagram, and Structured Text—the module provides versatile control strategy implementation for industrial operations.

Equipped with 16 analog inputs, 8 analog outputs, 32 digital inputs, and 32 digital outputs, the N0311GA supports mixed-signal applications, from sensor data acquisition to actuator control. Its redundant 24 VDC power inputs, industrial-grade CPU, and onboard memory make it suitable for harsh environments, including oil & gas, chemical, pharmaceutical, and power generation facilities. The module can be mounted in racks or integrated chassis, ensuring flexible deployment in DCS infrastructures.
