DST-803 distribution current intelligent isolator

Classification:

Power distribution analog input

The DST-803 distribution current intelligent isolator converts the direct current signal of the industrial field into the required signal, and transmits it to the control room through isolation, which effectively improves 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, relay output, RS-485 communication output function. Input, output and power supply are isolated to ensure the stability and reliability of the system.
