DK1000 series

DK1000G voltage current thermal resistance thermocouple universal input isolation transmitter

DK1000G isolation transmitter is a universal input signal isolation transmitter, which can realize the measurement, transmission and isolation functions of various commonly used industrial measurement signals. The function of local alarm relay can be set inside. The product is highly measured and the technical index is not false. The transmit output is 16 bit transmission. Non-cheap products are characterized by inaccurate PWM transmission, poor linearity, slow response, low accuracy and exaggerated product performance. The product has an isolation voltage of 2000 volts. This product can have communication function. 24 volt DC power supply mode.

Example selection

First cases: DK1000G-K-4MA20-IL:-200-IH:1370-OL:4-OH:20

The selection is: DK1000G isolation transmitter, the input signal is K type thermocouple, and the output is 4-20MA signal. The lower limit of range is - 200 degrees, the upper limit of range is 1370 degrees, the time-varying output of - 200 degrees is 4MA, and the time-varying output of 1370 degrees is 20MA.

Second cases: DK1000G-PT100-0V10

The selection is: DK1000G isolated transmitter, input signal is PT100 platinum resistance, output is 0-10V signal, customers have no special requirements for input and transmission, so the measurement range of input signal is the default of the system. The -200 time output is 0V and the output is 10V at 850 degrees.
