Overview:
        SunYuan ISOS D-P-U series products are the industry-leading small-sized (SIP7 Pin) low-cost PWM pulse width modulation signal isolation transmitter IC developed by Shunyuan. The duty cycle of the inverter, single-chip microcomputer, PLC/DCS, and instrumentation internal PWM square wave signal can be isolated and converted into standard 0-5V/0-10V analog signals to realize single-chip PWM signal DA conversion isolation amplification and transmission. control function.
 
        SunYuan ISOS D-P-U series products are especially suitable for DA conversion isolation transmission of industrial field PWM pulse width modulation signals, single chip microcomputer, field bus, Ethernet Internet of Things, PLC/DCS host computer for multi-channel sensor signal acquisition analysis and control. The internal SMD process structure and new technology isolation measures enable the device to achieve: 3000 VDC isolation of PWM signal input and analog signal output. And it can meet the requirements of industrial grade wide temperature, humidity, vibration and harsh working environment. Due to the volume limitation, the internal power supply of the product is not boosted and isolated, so the voltage value of the power supply to the product must be higher than the signal output voltage value of 3VDC or more. (For example, the output signal is 0-5V, the power supply voltage needs more than 8VDC, and the 9VDC or 12VDC power supply is optional). If the user needs the signal to be completely separated from the working power supply or the user's power supply voltage is lower than the signal output voltage, the company's IBS series of isolated power modules can be used to supply power, or directly use the company's ISO D-P-O-Q series products.
 
        SunYuan ISOS D-P-U series products are very convenient to use, and can realize the isolation and transmission of PWM signals and analog signals without any external components. The ultra-small (19.6X6.0X10mm) and standard PCB board mounting design of the 7-pin single-row in-line is designed to simplify the user system design options and reduce the volume of the product. Realize the miniaturization design requirements of user terminal products.
