USB data-logger S332

EthernetonlineRS-485

Overview
The S332 Display and Data Logger centralizes data acquisition, visualization, storage, and analysis into one platform. Designed for compressed air and industrial gas systems, the S332 delivers real time visibility across the entire network, from generation to point of use. Connect up to 150 channels and monitor your full compressed air network from a single 7 inch color touch screen.

One Device, Complete Visibility
Connect up to 150 channels and monitor your full compressed air network from a single 7 inch color touch screen. The S332 supports SUTO iTEC and third party sensors through Modbus/RTU, Modbus/TCP, analog, and digital inputs, enabling integration of existing measurement points without extra hardware.

Powerful Data Logging and Analysis
The integrated 10 GB data logger records up to 4.5 billion data points for long term trend analysis. Logged files can be exported for reporting, energy management, and compliance documentation. Customizable channel charts and real time trends support quick interpretation and action.

Compliance Built In
User management, audit trail, and electronic signature features support FDA 21 CFR Part 11 requirements. Role-based access with Admin, Operator, Auditor, and Manager accounts keeps system operation secure and fully traceable, making the S332 suitable for pharmaceutical and regulated industries.

Access From Anywhere
The integrated web server provides remote viewing and operation over a local network. With an optional 4G/LTE connection and the S4C Web platform, the device can be monitored, configured, exported, and upload data to a SaaS cloud from remote locations.

Reliable Alarm Management
Configurable channel-specific alarm thresholds with real time and historical alarm recording help detect issues early and reduce risk. Built-in relays (expandable up to ten) trigger immediate actions when limits are exceeded.

Robust and Easy to Install
The IP65 rated housing protects the device in industrial conditions. The S332 supports both wall and panel mounting and is available in AC and DC versions.

Applications

• Compressed air system operators
• Energy management projects
• Manufacturing and production facilities
• Pharmaceutical and regulated industries
• Factory-wide utility monitoring
• Multi-point sensor monitoring applications
