S332 Display, Data Logger & IoT Gateway

Unlock the full potential of your compressed air systems with the S332

The S332 is a very powerful yet cost-effective data logger, display, and IoT gateway solution, connectable with all SUTO sensors as well as third-party devices. Serving as the direct successor to the S330 / S331, the S332 brings every measurement channel into one central unit, delivering real-time visibility across your entire compressed air and industrial gas network.

One Device, Complete Visibility

Managing compressed air data across multiple measurement points can become complex and inefficient. The S332 centralises data acquisition, visualisation, storage, and analysis into one powerful platform.

Designed specifically for industrial systems, it provides instant access to critical information, from dew point and flow to pressure fluctuations, enabling swift action whenever anomalies occur to reduce unexpected downtime.

Key Benefits

Massive Data Capacity

The integrated 10 GB internal memory is capable of storing up to 4.5 billion data points, allowing for long-term trend analysis and effortless tracking of air system data.

High-Resolution Interface

Features a large, intuitive 7-inch color touch screen for easy, minimal-training operation and clear data accessibility.

Flexible Connectivity

Connect up to 150 channels. Supports SUTO iTEC and third-party sensors through Modbus/RTU, Modbus/TCP, analog, and digital inputs without requiring extra hardware.

Access from Anywhere

An integrated web server allows remote viewing, configuration, and data export over your local network. Optional 4G/LTE connectivity enables seamless cloud monitoring via the S4C Web platform.

Compliance Built-In

Full support for FDA 21 CFR Part 11 requirements, including role-based user management, electronic signatures, and secure audit trails—ideal for pharmaceutical and regulated industries.

Reliable Alarm Management

Configurable channel-specific alarm thresholds with real-time and historical recording. Built-in relays trigger immediate action when limits are exceeded.

Why Upgrade from the S330 / S331?

The S332 replaces the S331 with significant operational upgrades while remaining fully compatible with existing Modbus sensor networks without any required changes.

Is the S332 backward compatible with my existing sensors? Yes, absolutely. The S332 is designed as a direct drop-in replacement for the S330 and S331. All your existing SUTO or third-party Modbus/RTU and Modbus/TCP sensors will connect without requiring any changes to your current hardware.

How many sensors or measurement points can I connect? You can connect and monitor a massive array of devices. The S332 supports up to 150 Modbus input channels, which is a significant upgrade from the 58 channels supported by the older models.

How do I access my compressed air data remotely? The S332 features an integrated web server. Once connected to your facility’s local network, you can view real-time data, adjust configurations, and export logs directly from your PC or smartphone web browser. If you need off-site cloud access, the optional 4G/LTE gateway links seamlessly with the S4C Web platform.

How long will the internal memory last before filling up? The 10 GB internal drive stores up to 4.5 billion data points. To put that into perspective: if you are monitoring 50 different channels and taking a reading every single second, the device will log continuously for about 530 days (nearly 1.5 years) before running out of space.

Is this system compliant for pharmaceutical or strict food-grade applications? Yes. The S332 comes with full support for FDA 21 CFR Part 11. It includes secure audit trails, electronic signatures, and role-based user management, making it fully compliant for highly regulated industries.

What happens if my compressed air system drops in pressure or spikes in moisture? You can configure specific alarm thresholds for any channel. When a limit is breached, the S332 records the event in its history and triggers its built-in alarm relays (expandable up to 10 relays), which can be wired to sound sirens, flash beacons, or automatically shut down critical valves.
