Vega SI-12 RELAY pulse counter is designed for counting of pulses incoming to 4 independent inputs, further accumulating and transmitting of this information to the LoRaWAN® network, and for controlling low-power actuators by means of built-in relays.
In addition, Vega SI-12 RELAY can be used as a security device - all inputs can be configured as security inputs.
The counter has two relay outputs and can be used as a control device.
The pulse counter can be used for any utilities’ meters and industrial equipment with output of dry reed switch type or open-drain type.
