DST-805 temperature transmission isolator

Classification:

Thermocouple, resistance input

The DST-805 temperature transmission intelligent isolator converts the thermal resistance or thermocouple signal in 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 automatic control system of the industrial production process. Using patch technology, modular structure design, small size and 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.

Keywords: Isolator
