WSLRW-LRO is a LoRaWAN node with latching relay output to electrically operate switch that uses a small electrical signal to control a larger electrical circuit. It works by energizing a ON relay coil or OFF relay coil, which creates a magnetic field that moves an armature to open or close contacts, allowing or interrupting the flow of electricity. This makes relays essential for controlling high-power devices with low-power signals.
The node will transmit data in kilo-meters distance to the LoRaWAN gateway from any brand on the market. LoRaWAN relay nodes are used in various applications to remotely control devices with low power consumption over long distances. Latching relays are commonly used in applications where it is necessary to maintain the last state after a power failure such as industrial machinery, automate home systems like lighting and heating, regulate pumps and valves in water treatment plants, optimize irrigation in agriculture, control energy distribution in buildings, and operate urban infrastructure such as streetlights and traffic signals.
