The NORVI GSM-AE07 series is a compact DIN rail programmable controller built around the versatile ESP32-WROOM32 System-on-Chip. It is specifically engineered for industrial IoT applications where reliable cellular connectivity is paramount. Depending on the model, the device can be equipped with a Quectel EC21-G module, providing robust 4G LTE, 3G, and 2G fallback connectivity for remote monitoring and control. The controller is fully programmable using the accessible Arduino IDE or the advanced ESP-IDF framework, offering a flexible development path from rapid prototyping to professional deployment. A built-in 0.96-inch OLED display and a front-panel button provide essential local status information and interaction.

The GSM-AE07 series offers two primary models to suit different output requirements. The GSM-AE07-R-G variant provides five 5A relay outputs, suitable for directly switching higher-power AC or DC loads. The GSM-AE07-T-G model features four transistor outputs for fast-switching applications. Both models are equipped with seven industrial 24V DC digital inputs, configurable as sink or source, ensuring easy integration with standard industrial sensors and switches. An RS485 port is standard, enabling communication with a wide array of industrial devices and networks. The controller also supports expansion via additional I/O modules, allowing the system to be scaled to meet specific application demands.

This controller is designed to function as a robust cellular IoT gateway or remote PLC. It can connect to cloud platforms, transmit sensor data, and receive control commands from anywhere with cellular coverage. This makes it an ideal solution for applications in remote locations such as pump stations, agricultural monitoring, environmental data collection, and distributed utility management, where traditional wired network access is unavailable or impractical. Its compact DIN-rail mountable enclosure is designed for easy integration into industrial control panels.

The NORVI GSM-AE07 series is built for industrial environments, with a rugged design and an IP20 protection rating suitable for control cabinet installation. It is powered by a 24V DC supply. The controller combines powerful wireless capabilities, flexible I/O, and an open programming ecosystem, making it an excellent choice for system integrators and OEMs seeking to implement smart, connected, and remotely managed industrial automation solutions.
