The Vega SI-23-485 LoRaWAN® converter is designed to organize automated collection of readings from utility meters or industrial equipment. The converter has one RS-485 digital interface and two pulse inputs. The inputs can be configured both to count pulses and to implement security functions.
The converter is powered from the AC mains, and in the event of a power outage, the converter will automatically switch to power from the backup battery.
