Description
The SH-LTE681 is an industrial-grade router equipped with 8×10/100/1000Base-T copper ports and 2x1000Base-X SFP slots. It integrates high-performance real-time processors, network interfaces, and communication interfaces of universal specifications, along with rich software functions—making it a hyper-converged device that works as an industrial router, IoT gateway, or serial server, adapting to diverse industrial needs.
Built with excellent industrial quality, it can operate stably in extremely harsh environments (such as high-temperature workshops, outdoor remote sites, or dusty industrial areas), resisting the impact of harsh conditions on device performance. The 8 Ethernet copper ports serve as LAN interfaces, easily connecting multiple wired devices like industrial computers, HD surveillance cameras, and IoT sensors, meeting the high-density access needs of small and medium-sized industrial scenarios.
It also features super scalability: interface expansion is convenient and fast, and device upgrades can be completed without replacing the entire unit—greatly reducing maintenance costs and avoiding operational interruptions caused by hardware replacement. As a hyper-converged product, its multi-function integration eliminates the need for multiple separate devices, saving installation space and simplifying on-site management.
The router adopts a fanless design and a high-strength metal casing: the fanless structure avoids dust accumulation and equipment failure caused by fan wear, while the metal casing enhances anti-collision and anti-interference capabilities, extending the device’s service life. Additionally, it supports rich IO expansion options, including 1 Lora interface, 1 NVMe interface, and 1 4G interface—further expanding its application scope in IoT data transmission, storage, and wireless connectivity scenarios.
