ISO D-P-O-Q PWM to 4-20mA/0-10V Isolated Converter IC

 SunYuan ISO D-P-O-Q series products are SunYuan's newly developed industry-leading technology small size (SIP12 Pin) low-cost PWM pulse broadening signal isolation transmitter ICs. The duty cycle of output PWM square wave signal of microcontroller, PLC/DCS, instrumentation can be isolated and converted to standard 4-20mA/0-10V analog signal to realize the isolated amplification and display control function of microcontroller PWM signal.

        SunYuan ISO D-P-O-Q integrates multiple highly isolated DC/DC power supplies, analog amplifier and converter circuits, PWM signal isolation control circuits, etc. in the same module, which is especially suitable for DA reduction isolation and transmission of PWM signals in the industrial field, and the acquisition and analysis of multiple sensor signals by single-chip microcomputers, field buses, Ethernet IoT, and PLC/DCS upstream computers. The internal integrated high-efficiency DC-DC isolated power supply provides power to the internal output conditioning circuit, DA conversion circuit and output signal isolation circuit respectively.  SMD process structure and new technology isolation measures so that the device can achieve auxiliary power supply and PWM signal input, analog signal output 3000VDC triple isolation. And can meet the industrial grade wide temperature, humidity, vibration of the site of the harsh operating environment requirements.

        SunYuan ISO D-P-O-Q series products are very easy to use, without any external components to achieve the PWM signal and analog signal isolation and transmission function. The ultra-small size (33.0X15.5X10.5mm) of 12-pin single-row in-line and standard PCB board mounting design effectively simplifies the user's choice of system design options and reduces the volume and wiring costs. The products are available in PCB board mounted IC package, DIN35 standard rail mounting and PIM panel display embedded mounting. the DIN rail mounting can realize the signal one-in-one-out, one-in-two-out isolation transmission function. PIM panel embedded intelligent transmission meter can realize various functions such as sensor analog signal isolated display, alarm control and long-distance distortion-free transmission.  Widely used in metallurgy and mining, petrochemical industry, electric power equipment, medical instruments, industrial automation, new energy facilities and military scientific research and other fields, the user can choose the appropriate products according to the needs of the site
