Connect industrial equipment and remote networks in Japan through Giteki-certified cellular connectivity with download speeds up to 3.4 Gbps. Teltonika RUTM50200800 combines a Quectel RM520N-GL modem with support for standalone and non-standalone 5G, plus backward compatibility with LTE Cat 19 download and Cat 18 upload services. Two SIM slots support automatic switching when signal weakens, a data allowance is reached or a connection fails. SIM idle protection can periodically establish a connection on the unused SIM to help prevent inactivity blocking. Connect local equipment through four Gigabit Ethernet LAN ports and a separate Gigabit Ethernet WAN port. Dual-band Wi-Fi 5 supports rates up to 867 Mbps, MU-MIMO and up to 150 simultaneous wireless connections. Wired WAN, cellular and Wi-Fi WAN can participate in automatic failover, while load balancing distributes Internet traffic across multiple WAN connections. Bridge and passthrough modes accommodate installations where another device handles routing. Port-based and tagged VLANs separate traffic, and WireGuard, OpenVPN, IPsec and other VPN options support remote network access. Operate from a 9–50 V DC supply through the industrial power connector, or use supported passive power on LAN1. Maximum power consumption stays below 15.5 W. RutOS provides browser management, SSH, SNMP and Teltonika RMS integration. A digital input and open-collector output connect equipment events to email, SMS or RMS notifications. Modbus, OPC UA, MQTT and DNP3 support industrial data exchange, while USB 2.0 accommodates storage and serial adapters. This Japan-market version combines Giteki certification with the specified global modem, making its regional approval a concrete selection criterion.
