DRG-1801 Frequency isolated safety barrier

Picture Name

Classification:

DRG series

The frequency -input isolated safety gate can transmit the frequency signal generated by the instrument in the danger zone to the safety zone, and then output it. The input adopts hysteresis comparison circuit with high anti-interference performance and provides power to the field instrument at the same time. The product needs independent power supply, power supply, input and output are completely isolated.

Number of channels:

1input/2outputs

Input:
