Dragino LT-22222-L LoRaWAN I/O Controller
The Dragino LT-22222-L is a LoRaWAN-based I/O controller designed for long-range, low-power monitoring and control applications. It provides a practical way to connect digital inputs, digital outputs, relay outputs, and analogue signals to a LoRaWAN network, enabling reliable remote control and telemetry without complex wiring.
LoRaWAN Connectivity The LT-22222-L operates exclusively on LoRaWAN, making it well suited to private and managed LoRaWAN networks where long range, low power consumption, and predictable coverage are required. It supports secure uplink and downlink communication for both monitoring and control use cases.
Designed for Remote Control and Monitoring With multiple digital and analogue interfaces, the LT-22222-L can monitor input states, read analogue sensor values, and control external equipment via relay outputs. Common applications include irrigation and pump control, building automation, alarm monitoring, smart agriculture, and general industrial I/O control.
Enhanced Functionality with Telemetry2U Integration While the LT-22222-L can be connected to compatible third-party platforms, Telemetry2U is the recommended option for customers seeking a supported, end-to-end LoRaWAN solution. When integrated with the Telemetry2U IoT platform, the device can be configured with dashboards, historical data logging, alerts, and remote control capabilities, allowing users to move from raw I/O data to actionable outcomes.
