A versatile DIN-Rail IIoT Gateway with 4G/Wi-Fi, 4×RS485, 2×CAN, and 8×I/O for robust industrial communication and edge computing
The MaxGate500 Series is a high-performance industrial edge computing gateway engineered to bridge the gap between OT and IT systems in the era of the Industrial IoT (IIoT). Built on a powerful 1.2GHz Tri-Core ARM Cortex-A7 processor and a real-time ARM Cortex-M0 co-processor, this smart gateway delivers the high bandwidth and low latency required for demanding industrial automation applications.
Featuring a rich selection of interfaces, the MaxGate500 provides seamless connectivity for both modern and legacy industrial equipment. It includes 2 Fast Ethernet ports, 4 isolated RS485 serial ports, 2 isolated CAN bus ports, and 8 channels of digital I/O, making it an ideal all-in-one solution for data acquisition, protocol conversion, and device monitoring. With optional 4G LTE and Wi-Fi/Bluetooth modules, the gateway ensures continuous network uptime through robust multi-network redundancy and automatic failover.
The MaxGate500 runs on an open Ubuntu 20.04 operating system, offering a familiar environment for developers. Support for Docker containers simplifies the deployment and management of custom applications, accelerating the development of your edge computing solutions. Security is paramount, with integrated support for advanced VPN protocols (such as OpenVPN and IPsec) and compatibility with the MixConnect platform to establish secure tunnels for remote PLC programming, monitoring, and maintenance.
Engineered for durability, the MaxGate500 features an industrial-grade, fanless design that guarantees reliability in extreme temperatures ranging from -40°C to +75°C. Its compact, DIN-rail mountable form factor and wide-range 12~48V DC power input make installation simple in any control cabinet. This powerful and versatile gateway is the perfect choice for applications in factory automation, smart cities, renewable energy, intelligent transportation, and smart mining.
