Industrial Dual-SIM 4G/LTE Router with Serial & DI/DO.

Running RobustOS (Linux-based) with a C/C++ SDK, Security is comprehensive: IPsec, OpenVPN, GRE, and WireGuard are available, with Web/CLI/SMS management and RCMS for fleet monitoring, configuration, and updates.

Install flexibly with PoE-PD (optional) on the WAN port, while Wi-Fi (AP/Client, 2.4 GHz) adds wireless backhaul or local access as needed. Integration is straightforward: RS-232/RS-485, DI/DO, and LAN/WAN modes simplify connection to PLCs, meters, and on-site controllers.
