MDSC344E series thermal resistance temperature 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 Three Wire Pt100 , Cu50 , Cu100 , Pt50 Or other types of Thermal resistance signal, after linearization, transform into linear with 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.

High precision, high linearity, high stability
Modular design, small volume, low power consumption, suitable for intensive installation
Reasonable structure, easy plugging, installation, disassembly and maintenance is more convenient and simple
Technical indicators
Input signal: Cu50 , Pt100 , Cu100 , Pt50
The excitation current is less than or equal to: 0.2mA
The lead wire resistance is less than or equal to: Twenty Omega / Line
Output signal: Two Wire 4~20mA
Output voltage: 16~30V That is, the operating power supply voltage
Conversion accuracy: + (0.2%F.S Delta R>40 Omega )
. 0.4%F.S (40 Omega = Delta R More than Twenty Omega )
Temperature drift:. 100ppm/ C
Dielectric strength: input / The output is more than 2000VAC ( 1min )
Insulation resistance: input / The output is more than 100M (omega 500VDC )
Remarks： isolator The thermal resistance between the wire and the wire must be the same length, conductor resistance value will not increase the measurement error.
DCS The Board shall be provided for Two Wire input mode (distribution mode).
