Introduction:

SunYuan ISOH 4-20mA is our the newest developed two-wire passive 4-20mA current loop isolation module in industry circles with the highest isolation voltage (10KVAC) and small size (16-pin single-in line SIP16 Pin) &low-cost. This new product is a passive analog signal isolation hybrid integrated circuit of front-end 4-20mA current signal input and back-end 4-20mA output, IC internal including the current signal modulation and demodulation circuit, signal coupling isolation conversion circuit, etc. . This new product adopts the unique Sunyuan technology magnetic-electric coupling isolation and high-efficiency loop power take-off invention technology, which effectively solves the problem of dependence of the signal isolation circuit on the power supply during operation, and can realize high-precision, high-linearity 10KV anti-EMS high-isolation transmission of 4-20mA (0-20mA) signal between the industrial field sensors & instrumentation, PLC &DCS. The 16pin SIP small size (46X22X12mm) standard PCB mounting design can be embedded in the instrument panel, sensor, PLC and other operation control boards, which simplifies the user system design choice and reduces the volume and wiring cost.

ISOH 4-20mA adopts Sunyuan's unique electromagnetic isolation coupling technology, which does not require independent power supply and has a small input equivalent resistance inside, which makes the input voltage of the IC reach an ultra-wide range (8.5~32VDC). The technical products can be directly connected in the two-wire 4-20mA or 0-20mA working circuit of industrial field PLC, instrumentation and sensor, physical transmitter and other devices, and can achieve 4-20mA signal anti-interference isolation, long distance distortion-free transmission without external auxiliary power supply.. The integrated process and new technology isolation measures inside the product enable the input and output ports of the device to achieve a high isolation insulation voltage of 10KVAC and can meet the harsh environment requirements such as wide temperature, humidity and vibration in the industrial field. The products are IC module package and DIN35 Rail-mounted packaging, It is widely used in track voltage monitoring, generator or motor safe operation monitoring, power transmission and distribution remote monitoring, instrumentation and sensor signal transmission and reception, medical equipment safety barrier, industrial intelligent control, nuclear power equipment and other fields.
