Industrial IoT Edge Gateway – Multi-I/O, 4G LTE, RS232/RS485, Local Processing

This Industrial IoT Edge Gateway (non-touch version) is a high-performance edge computing device designed for field data acquisition, real-time processing, automation and secure communication in demanding industrial environments. It connects directly to sensors, PLCs, instruments, meters and field controllers through extensive I/O, including RS232, RS485, digital inputs, relays, analogue channels, I2C, TTL and Ethernet.

Powered by an industrial ARM processor, the gateway collects, filters and processes data locally before sending it to the cloud via 4G LTE. With support for Modbus RTU/TCP, MQTT, transparent TCP/UDP, and robust VPN security, it integrates seamlessly into both modern IIoT systems and legacy SCADA networks.

Designed for applications such as water & wastewater, gas & oil, industrial automation, building systems, energy monitoring, smart city infrastructure, vending machines and remote assets, this gateway delivers stable performance in harsh environments. Local data storage (flash + microSD) ensures continuity even during network outages.

We keep stock in Australia, offer local technical support, and help you integrate this gateway with ProSight or any third-party IoT/SCADA platform.
