MDSB343E series of thermocouple temperature isolation type Safety gate The power supply circuit. 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. Isolated gate From the terminal energy into the limit of intrinsically safe dangerous places, so as to ensure the safety and explosion-proof system.

Output voltage: 16~30V That is, the operating power supply voltage
Conversion accuracy: + (0.2%F.S Delta V>10mV)
. 0.4%F.S (10mV More than Delta V More than 5mV)
Temperature drift:. 100ppm/ C
Dielectric strength: input / The output is more than 2000VAC ( 1min )
Intrinsically safe / Non intrinsically safe, more than 2000VAC ( 1min )
Insulation resistance: input / The output is more than 100M (omega 500VDC )
Remarks： Safety gate The connection between the thermocouple compensation wire to must use the same type, otherwise it will increase the measurement error.
CJC For the cold end compensation of thermocouple, has been fixed on the special terminal.
DCS The Board shall be provided for Two Wire input mode (distribution mode).
