DST-801 voltage/current smart isolator

Classification:

Analog Input

DST-801HV high-voltage voltage intelligent isolator converts the DC voltage signal in the industrial field into the required signal, which is isolated and transmitted to the control room, effectively improving the anti-interference ability of the industrial production process automatic control system. Full use of patch technology, modular structure design, small size, low power consumption. With analog output function. Input, output and power supply are isolated to ensure the stability and reliability of the system.

Keywords: Isolator
