One device to connect, monitor, and share your compressed air data, with up to 150 channels, gateway connectivity, and IoT ready remote access.
SUTO iTEC is pleased to announce the release of the S332 Data Logger with Gateway and IoT Capabilities. The S332 centralizes data acquisition, visualization, storage, and analysis for compressed air and industrial gas systems, giving you real time visibility across your entire network from a single 7 inch touchscreen.
Connect up to 150 Modbus/RTU channels and monitor every measurement point in one place. As a gateway, the S332 links your sensors to HMI, SCADA, and external systems over Modbus/RTU, Modbus/TCP, and USB, so your data flows where your teams and tools need it.
The integrated 10 GB data logger records up to 4.5 billion data points for long term trend analysis, with file export for reporting, energy management, and compliance documentation. Built in IoT capabilities take it further: an integrated web server enables remote monitoring and operation, with optional 4G/LTE upload to the cloud.
For regulated industries, the S332 includes user management, audit trail, and electronic signature features that support FDA 21 CFR Part 11 requirements, with role based access for Admin, Operator, Auditor, and Manager accounts. The rugged IP65 housing keeps the device protected in tough industrial conditions.
The S332 replaces the S331 with a larger display, significantly expanded storage, and full compliance features. Existing Modbus sensor networks connect without changes.
