General Description:
ISO 4-20mA current chip is a kind of isolated interface that contains current signal modulate-demodulate and isolated coupled circuit. To meet the requirements of long distance transmission with little distortion, only little equivalent resistance enables a wide input range (7.5-32VDC) of the IC input available. To meet the requirements of 3KVDC isolation, the wider operating temperature range, humidity and quiver, we adopt the fully SMT ceramic PCB, printed resistor techniques and the latest techniques. ISO 4-20mA series are easy to be used with no external components linked, and also can be realized 4-20mA current loop isolation or signal counterchanging easily. Fix up: PCB Soldering or DIN 35.
