ZLT IR20Z

The ZLT IR20Z is a high-performance, industrial-grade 4G LTE gateway and router designed to deliver reliable, secure wireless broadband connectivity in challenging environments. Its core function is seamless conversion of cellular 4G network data into 100M wired Ethernet (2 ports) and optional 2.4 GHz Wi-Fi (802.11 b/g/n), providing critical network access for devices and systems where traditional wired infrastructure is impractical.

●Engineered for Industrial Resilience and Intelligence
Built around the ZX297520V3E chipset and supporting global 4G bands (FDD/TDD-LTE, WCDMA, GSM), the IR20Z thrives in harsh conditions with an operating temperature range of -20°C to 60°C and wide 9-36V DC power input. Key hardware features include dual SIM slots (2FF) for redundancy, external antenna interfaces (2x LTE, 2x Wi-Fi optional), and versatile industrial I/O: a software-switchable RS232/RS485 serial port and DI/DO interfaces. This compact (104x126x26mm), low-power (<6W) device is ideal for integration into AGVs, security robots, excavators, industrial control systems, and remote monitoring sites.

●Advanced Software for Secure Integration and Management
The IR20Z excels beyond simple connectivity. It acts as a protocol gateway, integrating and processing data from diverse devices using MODBUS, MQTT, and serial-to-TCP transparent transmission for seamless information flow. Robust software features include multiple VPN protocols (PPTP, L2TP, IPSEC IKEv2), comprehensive firewall capabilities (IP/MAC/URL filtering, DMZ, port mapping), and extensive remote management options (TR069, Telnet, HTTP/HTTPS). Support for IPv6/IPv4 dual-stack, static/DHCP routing, NTP, APN, and SNMPv3 ensures flexibility and future-proofing. Security is enhanced through multi-level user management, WPA3 Wi-Fi encryption (optional), and secure boot/login mechanisms.

●Reliable Deployment for Critical Networks
Whether enabling wide-area connectivity for remote assets or facilitating local area network convergence in factories and enterprises, the ZLT IR20Z provides a secure, manageable, and resilient networking foundation. Its combination of industrial-hardened design, versatile interfaces, and powerful software makes it a trusted solution for demanding IoT and industrial communication requirements.
