SunYuan ISOS 4-20mA is one of the smallest size (SIP 7Pin) low cost passive 2-wire 4-20mA loop powered signal isolator
IC. ISOS 4-20mA is a kind of 4-20mA current signal input, 4-20mA output passive analog signal isolated integrated circuits. Inside
the IC, there is current signal modulation and demodulation circuit, signal coupling isolated conversion circuit,etc. The unique
magneto-electric isolation and efficient loop power extraction technique are adopted in solving the power supply requirements in
4-20mA (0-20mA) current signal isolation and transmission among sensors, meters, PLC, DCS. SIP 7pin, extra small size
(19.5x12.5x9.8mm), the isolator can be easily installed in PCB, meters, sensors, PLC and other panels, it can largely reduce
customers’ cost and simplify the design plan.
The low input equivalent resistance makes the IC module achieve wide range input voltage (8.5~28VDC) to realize the
long-distance, non-distortion transmission of signals without external power supply. By adopting SMD technological structure and
new isolation technology, the modules posses the features: 3KVDC isolation between signal input and output (total isolation type),
and operates in normal in abominable industrial conditions like wide temperature, humidity and vibration.
Sunyuan ISOS 4-20mA has the following features: small size, easy to use, can be easily installed in the other devices, it can
realize 4-20mA or 0-20mA current loop signal acquisition and isolated conversion with high accuracy without any external
components. The signal isolator has two types of package, small size PCB-mounted package, 35mm DIN rail-mounted package.
The 35mm DIN rail-mounted products can be 1-input 1-output, 2-input 2-output, 3-input 3-output and 16-channel isolation, etc.
