LT-22222-L LoRaWAN I/O Controller

LT-22222-L LoRaWAN I/O Controller


The LT-22222-L LoRaWAN I/O Controller provides a set of digital and analog I/O connections for connecting to a wide range of potential sensors or devices. It contains several different I/O Interfaces:

  • 2 x Digital Input
  • 2 x Digital Output
  • 2 x Relay Output
  • 2 x 4-20ma Input
  • 2 x 0-30v ADC Input

The LT-22222-L  I/O Controller is designed to simplify the enablement of LoRaWAN I/O monitoring and control.  With the wide range of I/O choices you can easily integrate with almost any type of sensor or transducer, and use the digital or relay outputs for control.

Product Description

The LT-22222-L is configured as a LoRaWAN OTAA Class C mode device by default. It has preset OTAA keys to join ant LoRaWAN network. To connect to a LoRaWAN network, via  LoRaWAN gateway, the user needs to input the OTAA keys in the LoRaWAN network server and power on the LT-22222-L. It will auto join the network via OTAA.
