Dragino LT-22222-L LoRa I/O controller

The Dragino LT series I/O modules are long-range LoRa I/O controllers. It contains various I/O interfaces such as: analog current input, analog voltage input, relay output, digital input and digital output, etc. LT I/O modules are designed to simplify the installation of I/O monitoring.

LT I/O controllers allow the user to send data and reach extremely long distances. They provide ultra-long distance communication with broadband spectrum and high immunity, while minimizing current consumption. They are focused on professional wireless sensor networks, such as irrigation systems, smart meters, smart cities, building automation and so on.

LT I/O controllers aim to provide simple and inexpensive installation using LoRa wireless technology.

The environment of use includes:

1) If the user’s area has LoRaWAN service coverage, he can simply install the I/O controller and configure its connection to the LoRaWAN provider via a wireless network.

2) The user can install a LoRaWAN gateway locally and configure the controller to connect to the gateway via a wireless network.
