SunYuan  ISOH 4-20mA-F is a two-wire passive 4~20mA current loop isolation distributor module with 10KV high voltage isolation, small size and low cost. Which is the highest voltage isolation amplifier IC on the market and developed by Sunyuan Technology. This new product could get power from the active equipment and supply for the passive sensor, at the same times, receive 4~20mA current signal from two-wire sensor or other instrumentation and output a isolated 4~20mA signal of the same linearity and same scale. The new product can realize high precision, high linearity and 10KV anti-EMC interference high isolation transmission and power distribution between industrial field sensor and instrument, PLC, DCS.

Inside the ISOH 4~20mA-F module, there are current signal modulation and demodulation circuit, signal coupling isolation and conversion circuit, and high efficiency DC-DC boost circuit, etc. circuit. DC-DC boost circuit supply power of 16~21.5V for two-wire passive sensor or PLC, DCS equipment, be convenient to the signal measuring, long-distance transmission and isolation for passive sensor, meets the needs of users to transmit distortion-free signal in long distance without power supply. This IC was designed for the two-wire powered loop (explosion-proof) of series connection between 24VDC and sampling resistors (load resistance), it is matched with the analog input interface board (host machine), PLC, DCS or other instruments (With active load in analog input port) commonly used in industrial fields. The integrated process and isolation technology which inside the product makes the input and output signal reach 10 KV AC voltage high isolation and insulation, and meet the harsh environment requirements in industrial site which with industrial grade wide temperature, damp, vibration, etc.

The ISO 4-20mA-F product is very convenient to use, it can realize the isolation, transmission and conversion of the two-wire 4-20mA signal without external adjustment circuit. The product's unique electromagnetic isolation mode and high-efficiency power distribution technology effectively solve the problem of dependence of the current signal isolation and transmission for sensors and transmitter to power supply, and achieve the precision and isolation transmission of 4~20mA standard signal. SIP 16 Pin PCB mounted and DIN 35 Rail mounted packages are available, which were widely used in rail traffic voltage monitoring, power generator or electric motor safety operation monitoring, electric power transmission and distribution long distance monitoring, signal transmission and reception between instrument and meter, medical equipment isolation safety barrier, industrial intelligent control, nuclear power, etc. field.
