Vega SI-12 pulse counter is designed for counting of electrical pulses incoming to 4 independent inputs, further accumulating and transmitting of this information via the LoRaWAN™ protocol to the gateway through wireless communication within 860-1000 MHz frequency band. The counter is powered by a soldered battery with up to 10 years life up. The counter can be powered by the 5V external power supply, i.e. it can be either of class A or class C. In addition, Vega SI-12 can be used as a security device - any of four inputs can be configured as security inputs. The pulse counter can be used for any utilities’ meters and industrial equipment with pulse output like a herkon or an open-darin output.
