Product introduction
MDSC343E series of thermocouple temperature change isolator The power supply circuit. Mounted as a guide rail, the base and the host can be separated from the plug, easy installation and maintenance. Series of products rich, can handle the current, voltage, thermal resistance, thermocouple, switch and other industrial products are widely signal. The application in building material, metallurgy, electric power and other industries, effectively restrain all kinds of interference signal.
function
The scene K , S , E , B , R , T , J , N Thermocouple etc. sensor The output signal, After isolating the linear processing, and converted into a linear relationship with the temperature. Two Wire current signal output. The output circuit of power supply, power does not need to work independently. Online index number and temperature range. Optional One enter One A.
