Small Volume PWM Pulse Width Signal to Analog High Precision Isolated Transmitter IC: ISOS D-P-U Series

       SunYuan ISOS D-P-U series products are SunYuan's newly developed industry-leading technology small size (SIP7 Pin) low-cost PWM pulse broadening signal isolation amplifier transmitter ICs. Can be inverter, microcontroller, PLC / DCS, instrumentation, the duty cycle of the internal output PWM square wave signal by isolation converted to standard 0-5V / 0-10V and other analog signals, to achieve microcontroller PWM signal DA conversion isolation and amplification and transmission control functions.

         SunYuan ISOS D-P-U series products are especially suitable for industrial field PWM pulse broadening signal DA conversion isolation transmission, microcontroller, fieldbus, Ethernet Internet of Things, PLC/DCS host computer on multiple sensor signal acquisition analysis and control. Internal SMD process structure and new technology isolation measures enable the device to achieve: PWM signal input, analog signal output of 3000VDC two isolation. And it can meet the requirements of industrial grade wide temperature, humidity, vibration of the harsh working environment in the field. Due to the size limitation, the internal power supply of the product is not boosted and isolated, so the power supply voltage must be more than 3VDC higher than the signal output voltage. （For example, if the output signal is 0-5V, the power supply voltage needs to be more than 8VDC, 9VDC or 12VDC is optional.）。If the user needs to isolate the signal from the working power supply, or if the user's power supply voltage is lower than the signal output voltage, the user can use our IBS series isolated power supply module to supply power to the user, or directly use our ISO D-P-O-Q series products.

         SunYuan ISOS D-P-U 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 (19.6X6.0X10mm) and standard PCB board mounting design of the 7-pin single-row direct insertion effectively simplifies the user's choice of system design options, reduces the volume of the product to reduce the space occupied by the board. Realize the miniaturization of user terminal product design requirements.
