Robustel R3000-QLB, Industrial Dual-SIM 4G/LTE Router
The Robustel R3000-QLB is an industrial dual-SIM 4G/LTE router designed to provide reliable cellular and Ethernet connectivity for industrial networking applications. It features an ARM processor running at 400 MHz, 128 MB RAM, and 256 MB flash. With support for two Mini SIM cards, the router provides flexible cellular connectivity for connected systems and remote installations.
The router provides 4 x 10/100 Mbps Ethernet ports that can operate as 4 x LAN or 3 x LAN + 1 x WAN. It also includes a software selectable serial interface supporting either RS-232 or RS-485, along with a USB 2.0 host port and Micro SD interface. These interfaces allow the router to connect with network equipment, serial devices, and other industrial peripherals.
The R3000-QLB supports a wide range of networking and routing functions through RobustOS. Network protocols include PPP, PPPoE, TCP, UDP, DHCP, ICMP, NAT, HTTP, DNS, NTP, SMTP, Telnet, HTTPs, ARP, VLAN, SSH2, and DDNS. It also supports IPsec, OpenVPN, GRE, and WireGuard VPN tunnels for network connectivity and remote access.
For network security, the router provides DMZ, anti-DoS, filtering, port mapping, and access control functions. Remote management is available through Web, CLI, and SMS, while routing support includes static routing and dynamic routing with BGP, OSPF V2, and RIP V1/V2. Smart Roaming V2 and RobustOS SDK support add further options for connected applications.
The Robustel R3000-QLB features a metal housing with IP30 ingress protection and supports desktop, wall mounting, and 35 mm DIN rail mounting. It operates from 12/24/48 V DC with a 9 ~ 60 V DC input range and provides reverse polarity and surge protection. With an operating temperature range of -40 ~ +75 °C, dual-SIM support, industrial interfaces, VPN capabilities, and flexible mounting options, it is designed for demanding industrial connectivity applications.
