Шлюз LTE Cat M1 і NB-IoT TRB255

Шлюз TRB255 LTE Cat M1 & NB-IoT с RS232, RS485 & Ethernet и 1 x LAN port 10/100 Mbps

Коммуникации >> LTE/3G роутеры и шлюзы

Производитель: Teltonika

TRB255 можно использовать для интеграции современного и устаревшего промышленного оборудования в одно решение через интерфейсы RS232, RS485 и Ethernet.

При этом его по-прежнему можно использовать с сетью 2G, однако в случае его отключения есть возможность переключиться на параметры подключения LPWAN.

TRB255 имеет широкий спектр промышленных и сетевых функций, таких как Modbus, управление по SMS, межсетевой экран, OpenVPN и другие.

Этот продукт совместим с системой удаленного управления Teltonika Networks (RMS).
