Vega SI-12 / User Manual INTRODUCTION This manual is designated for Vega SI-12 pulse counter (hereinafter – the counter) manufactured by Vega-Absolute OOO and provides information on powering and activation procedure, control commands and functions of the counter. This manual is targeted at specialists familiar with installation work fundamentals for electronic and electrical equipment.
Vega SI-12 pulse counter is designed for counting of pulses incoming to 4 independent inputs, further accumulating and transmitting of this information to the LoRaWAN network In addition, Vega SI-12 can be used as a security device - all inputs can be configured as security inputs.
