ISO 4-20mA-F is a kind of two wires 4-20mA-signal isolation amplifier. Inside the IC contains signal modulate-demodulate and isolated coupled circuit, the high efficiency DC-DC circuitry as well. The IC supplies 16V-21.5VDC to the two wires embedded power, offering the function of the two wires inductors signal testing, transmitting and isolation. The IC output is especially designed according to series 24VDC and sample resistor (or load resistor) two wires power supply loop (Anti-Explosion Function), which is also compatible to the popular analog interface, PLC, DCS or other measurements input interface. 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-F series products are easy to be used, and is simple to realize the function of two wires 4-20mA-signal isolation, transmission and interchanging without any external components linked.
