IoT gateway S335

industrialtelemetry4G

Product overview

The S335 IoT Gateway is a compact industrial gateway for compressed air monitoring systems. It aggregates data from field sensors and forwards it to monitoring software or cloud services, enabling centralized data access and remote management for small and large installations.

Key features

• Connects to factory systems via Modbus/RTU and Modbus/TCP
• Supports up to 16 Modbus/RTU sensors
• Remote monitoring via optional 4G modem and cloud integration
• Integrated web server for live data access and configuration
• Power supply loop for connected sensors (24 VDC loop-through)
• Mountable on wall or DIN rail
• Configuration import/export for simplified setup
• Universal compatibility with third-party sensors

Applications

Designed for compressed air system monitoring in industrial facilities, manufacturing plants and production sites. Integrates with S4M Smart Monitoring Software for real-time system visibility. With the optional 4G modem, secure remote data access and management are supported.
