The RF Solutions 725 telemetry system provides a simple and expandable, two-way, remote control switching. Each module has two switch inputs and two relay changeover contact outputs. They use the LoRa standard on 868 MHz frequency which offers long range and reliable communication in a variety of environments. Suggested applications include flood light, industrial environments, large arenas and stadiums. When two or more modules are paired together the relay outputs will follow the state changes of the other modules’ Inputs.

There are two models available depending on the range required. Note: Range is under optimal line-of-sight conditions:

RF Solutions 725-TRX8-1K - 725 Series 1 Km DIN Rail Transceiver (RS 125-8182)
RF Solutions 725TRX8-16K - 725 Series 16 Km DIN Rail Transceiver (RS 125-8183)

You can expand the system, adding extra inputs or outputs by daisy chaining one or more of the add-on modules together:

725-IP - 725 Series 4-Input Add-On Module (RS 125-8184)
725-OP - 725 Series 4-Output Add-On Module (RS 125-8185)
