Product introduction
MDSC322E series distribution isolator (HART) 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
This product is compatible with the distribution and isolation Two Modes: distribution mode, to the scene Two Wire TransmitterSupply, sampling Transmitter Output Two Wire current signal through the isolation after processing into Four Wire current isolation mode, sampling signal output; Four Wire current signal through the isolation output Four Wire current signal. The toggle switch product side built-in can set the input mode. This product is compatible with HART communication Can be used for intelligent. Transmitter . Optional One enter One A, One enter Two A, Two enter Two A.
