Product Description

The P0914QWG is a high-performance differential input module for the Foxboro I/A Series and EcoStruxure DCS. It measures the voltage difference between two input signals, providing superior noise rejection for critical process variables like differential pressure, flow, and high-accuracy temperature.

With a ±60 V input range, 0.1% accuracy, and 0.001 mA output resolution, the module ensures even the smallest process fluctuations are captured. Its rugged design allows operation in extreme temperatures from -40°C to +85°C, making it ideal for remote or harsh plant environments.

Technical Specifications

Key Features

Applications

• Differential pressure monitoring in chemical and petrochemical plants

• High-accuracy flow measurement in water/wastewater systems

• Remote or harsh industrial field enclosures

Frequently Asked Questions

• What is the advantage of a differential input? Measures the difference between two signals rather than relative to ground, providing strong EMI and noise immunity.

• Is it compatible with standard Foxboro baseplates? Yes, it integrates seamlessly with Foxboro I/A Series systems using standard mounting and power interfaces.
