Slim Size PWM to Current Signal Isolation Amplifier

Product Description

PWM pulse width signal DA conversion isolation transmitter:DIN3 D-P-O-Q

    SunYuan ISO D-P-O-Q series products are Sunyuan's newly developed industry leading small capacity (SIP12 Pin) low cost PWM pulse width modulation signal isolation transmitter IC. The duty cycle of the single chip microcomputer, PLC/DCS, and instrumentation output PWM square wave signal can be isolated and converted into a standard 4-20mA/0-10V analog signal to realize the isolation amplification and display control function of the single chip PWM signal.
 
    SunYuan ISO DPOQ integrates multi channel high isolation DC/DC power supply, analog amplification and conversion circuit, PWM signal isolation control circuit, etc. in the same module, especially suitable for DA reduction isolation transmission of industrial field PWM signal, single chip microcomputer, field bus, Ethernet IoT, PLC/DCS host computer for multi-channel sensor signal acquisition and analysis. The internal integrated high-efficiency DC-DC isolated power supply supplies power to the internal output conditioning circuit, DA conversion circuit and output signal isolation circuit. SMD process structure and new technology isolation measures enable the device to achieve 3000 VDC isolation of auxiliary power supply and PWM signal input and analog signal output. And can meet the industrial requirements of wide temperature, humidity, vibration and the harsh working environment.
 
      The SunYuan ISO D-P-O-Q series is very easy to use and can realize the isolation and transmission of PWM signals and analog signals without any external components. The ultra small 12 pin single row (33.0X15.5X10.5mm) and standard PCB board mounting design simplifies user system design options, reducing size and wiring costs. The product has an IC package mounted on the PCB, DIN35 standard rail mounting and PIM panel display embedded installation. DIN rail type installation can realize signal one-in-one-out, one-in-two-out isolation transmission function. The PIM panel embedded intelligent transmission table can realize various functions such as sensor analog signal isolation display, alarm control and long-distance distortion-free transmission.
