LongReach (LoRa) 4-Channel Relay
The LongReach 4-Channel Relay Module, combined with the LongReach Digital Transmitter Module, enables control of up to four electrical devices over extended distances. Based on LoRa technology, its range surpasses common wireless technologies like WiFi or Bluetooth, making it perfect for use in areas such as garages, outbuildings, and similar remote locations.

Expandable with Multiple Modules
The modules come with dip switches that let you choose from 256 available channels. A relay module will respond to any digital transmitter set to the same channel, allowing you to either use multiple transmitters with one relay module, or control multiple relay modules with a single transmitter.
Additional Features
Both modules are designed with screw terminals for simple connection of inputs, outputs, and 5V power—no soldering required. A power/communication LED indicator lights up when the modules are powered and blinks during transmission. The relay module also features four additional LEDs to display the status of each relay.
