Two make 4-20ma the application
Origin: Input time: 07-06-10 01:48:04English version

Two make the 4-20mA signal disconnector: (ISO 4-20mA)
ISO the 4-20mA electric current link isolation chip is the monolithic two systems isolation connection chip, this IC interior contains has the electric current signal modulation demodulation electric circuit, the signal coupling isolation transfer network and so on. The very small input equivalent resistance, enables this IC the input voltage to achieve the ultra width scope (7.5 - 32V), satisfies the user not to need the external power supply to realize the signal long-distance range, the non- distorted transmission need. The internal ceramic foundation plate, the printed resistor craft and the new technical isolation measure enables the component to achieve the 3KVDC insulation voltage and the industry 级宽 temperature, is moist, the vibration scene adverse circumstance request. Outside ISO the 4-20mA series product use extremely facilitates does not need to meet any part then to realize the 4-20mA electric current link isolation or the signal as soon as enters two, two enters two and so on the transformation function.

Two make 4-20mA signal isolation recuperating: (ISO 4-20mA-P)
ISO 4-20mA-P is one kind of two makes 4-20mA signal isolation recuperating, belongs to SUNYUAN ISO the 4-20mA series the product.
This IC interior contains has the electric current signal modulation demodulation electric circuit, the signal coupling isolation transfer network and so on. The very small input equivalent resistance, enables this IC gathers from the sensor return route to the signal voltage outside to achieve the ultra width scope (7.5 - 32V), satisfies the user not to need to meet the accessory power supply to realize the signal long-distance range, the non- distorted transmission need. This IC output is aims at 24VDC and the sample resistance (or called load resistance) connects the two-wire system power supply return route designs, meets the oral plate with the current popular simulation quantity input (on position machine), PLC, DCS or other measuring appliances simulation quantity input ports matches. The internal ceramic foundation plate, the printed resistor craft and the new technical isolation measure enables the component to achieve the 3KVDC insulation voltage and the industry 级宽 temperature, is moist, the vibration scene adverse circumstance request. ISO the 4-20mA-P product use is extremely convenient outside, only needs meets a 50K Omega multi- circles potentiometer to carry on ADJ to adjust, then realizes two to make the 4-20mA signal the isolation, the transmission and changes delivers the function or the signal as soon as enters two, two enters two and so on the transformation function.

Two make the 4-20mA signal isolation distributor: (ISO 4-20mA-F)
ISO 4-20mA-F is one kind of two makes the 4-20mA signal isolation distributor, belongs to SUNYUAN ISO the 4-20mA series the product.
This IC interior contains has the electric current signal modulation demodulation electric circuit, the signal coupling isolation transfer network, but also some high efficiency DC-DC electric circuit and so on. This IC is two 制配 electric appliances power distribution 16V~21.5V, has facilitated some two systems function and so on sensor signal survey, far biography, isolation. This IC output is aims at 24VDC and the sample resistance (or called load resistance) connects the two-wire system power supply return route (scene explosion-proof function) designs, meets the oral plate with the current popular simulation quantity input (on position machine), PLC, DCS or other measuring appliances simulation quantity input ports matches. The internal ceramic foundation plate, the printed resistor craft and the new technical isolation measure enables the component to achieve the 3KVDC insulation voltage and the industry 级宽 temperature, is moist, the vibration scene adverse circumstance request. Outside ISO the 4-20mA-F product use is extremely convenient, does not need to meet any component then to realize two to make the 4-20mA signal the isolation, the transmission and changes delivers the function.

Two make the 4-20mA signal isolation to change delivering: (ISO 1,003)
Two make the 4-20mA signal isolation to change delivering (ISO 1,003) is the monolithic two systems isolation connection chips, this chip interior contains has an electric current signal tone circuit, the photoelectricity coupling isolation transfer network and the demodulation electric circuit. This chip has 4-20mA the power line voltage scope width (16.5V-36V), the input equivalent resistance is small, linear higher characteristic. This chip may provide 5V/3.5mA the isolation voltage output, the 2.5V datum power source. The input signal voltage is 0-0.8V, corresponds 输入?in the signal road the electric current change. The input and the output side width crawls the electricity to be away from and the internal special insulation isolation measure causes this chip to be possible to achieve the 3KVDC insulation voltage
