GL300

Industrial LTE cellular router for DIN rail

DIN-rail router with dual SIM, RS232 and RS485, built to live inside the panel alongside the rest of the field equipment.

  • DIN rail mounting
  • 2 Ethernet · 2 SIM
  • RS232 + RS485
Hardware Industrial LTE cellular router for DIN rail — GL300

When the router has to live inside a panel, alongside the RTU and the rest of the equipment, form factor stops being a detail. The GL300 adds LTE connectivity, dual SIM and serial ports in a metal DIN-rail enclosure, with remote management from a cloud platform.

  • Built for the panel

    DIN rail mounting, alongside the RTU and the rest of the field equipment, with no extra adapters.

  • Layered redundancy

    Dual SIM and load balancing between wired WAN, WiFi and cellular: if one path fails, the unit stays online.

  • Serial to IP, no detours

    RS232 and RS485 with DTU function and Modbus RTU to TCP conversion, to bring serial devices onto the IP network.

  • Managed from the cloud

    Remote configuration, backup, reboot and firmware updates, with no need to visit the site.
