Product Overview The YZW400 series 4G industrial router is a highly integrated industrial-grade communication device that integrates remote networking, PLC/HMI remote control, 4G cellular communication and Wi-Fi routing. It has the characteristics of high cost performance, easy deployment and high reliability, and is designed for complex industrial Internet of Things (IIoT) application scenarios. Core Features 1. High-performance hardware architecture – Processor: Equipped with industrial-grade MT7628AN communication processor, it supports efficient multi-tasking and remote networking. – Wireless connection: – 4G cellular network: Supports China Mobile/China Unicom/China Telecom full network access, and can still be stably networked in harsh environments. – Wi-Fi: 2.4GHz high-speed low-latency access, supports concurrent connection of 50+ devices. – Industrial design: -40°C to 85°C wide temperature operation, passed EMC anti-interference certification. 2. Multi-protocol support and data acquisition – Full interface compatibility: – RS232+RS485 serial port: Supports remote transparent transmission of industrial protocols such as Modbus RTU/ASCII, PPI, MPI, and plug-and-play with PLC, sensors, and instruments. – Ethernet port: 10/100Mbps adaptive, seamlessly connected to industrial switches or upper systems. – Transparent transmission: Supports serial port to TCP/UDP protocol conversion, directly connected to the cloud (MQTT/TCP/UDP/Modbus). 3. Remote access and networking – SDLAN remote networking: – Remote access to PLC/HMI without public network IP, realizing cross-regional device interconnection. – VPN-level AES-256 encryption is used to ensure data security. – DTU transparent transmission: Bidirectional serial port to network protocol conversion, compatible with traditional device access. 4. Low power consumption and easy deployment – MX3.0 2×2 power interface, 9–48V industrial power input: Compatible with 24V system, supports reverse connection protection and surge protection. – One-click configuration: Web management interface, quick deployment in 10 minutes. Industry Applications The YZW400 series is widely used in: – Energy and power: smart substation monitoring, photovoltaic inverter data acquisition, distribution automation – Industrial automation: PLC remote debugging, predictive maintenance, MES system integration – Smart city: smart street light control, pipeline leakage monitoring, environmental sensing – Transportation and logistics: fleet remote management, cold chain monitoring, warehouse automation – Agricultural IoT: greenhouse control, livestock health tracking, smart irrigation Reasons for choosing YZW400 ✅ Out of the box: pre-set industrial protocol library (compatible with more than 90% PLC brands) ✅ Cost-effective: replace the “gateway + router + DTU” solution, reducing hardware costs by 30% Typical networking topology [PLC/sensor] → (RS485/Ethernet) → YZW400 gateway → (4G/5G/Wi-Fi) → cloud platform/SDLAN system
