![]() ![]() 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. The signal isolator has two types of package, small size PCB-mounted package, 35mm DIN rail-mounted package. 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. 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. 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. 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 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. Inside the IC, there is current signal modulation and demodulation circuit, signal coupling isolated conversion circuit,etc. Pepperl+Fuchs K-system signal converters receive signals from a hazardous area instrument i.e., temperature sensors, potentiometers or load cells and then convert and condition them into signals such as 0/420mA or 0/210V. ISOS 4-20mA is a kind of 4-20mA current signal input, 4-20mA output passive analog signal isolated integrated circuits. SunYuan ISOS 4-20mA is one of the smallest size (SIP 7Pin) low cost passive 2-wire 4-20mA loop powered signal isolator IC. 1-input 1-output, 2-input 2-output, 3-input 3-output.Rail-transit DC high voltage monitoring isolated safety barrier.Increasing circuit load resistance, will reduce the supply voltage available to power the transmitter that is generating the 4-20mA signal. Power: 24 VDC Mounting Style: DIN Rail Approvals: CE Warranty: 1 year. High power consumption compared to other analogue signal types. Power monitoring, medical equipment control and isolated safety barrier.
