   DIN 1X1 ISO U(A)-P-D-L1 series open-drain passive PWM high-current control output mode is mainly used in the receiving port of the load itself as an active receiving port. The receiving port is equipped with a pull-up voltage and a current-limiting resistor. The control occasions where the current connected to the transmitter is required to be in the sink power distribution mode. When the drain of the MOS tube is open, the current can reach 0~1A, and the output voltage amplitude of the PWM pulse width signal is determined by the external pull-up voltage. Products with open-drain passive PWM output can realize three isolation between the analog signal input terminal / PWM output terminal / auxiliary power supply 3000VDC.

   SunYuan DIN 1X1 ISO U(A)-P-D-L2 series active PWM voltage pulse width control output mode can be used to drive high-power passive loads directly , such as stepper motors and precision temperature-controlled heaters, etc. The drive current can reach 0- 1A, with strong load capacity.The amplitude of the PWM output voltage is determined by the power supply voltage of the module, so the product of this output mode can only realize the isolation of the analog signal input terminal / PWM output terminal and the auxiliary power supply. The auxiliary power supply and the PWM output terminal share the same ground. Users can use it according to their own site. You need to select the product corresponding to the output method.

   SunYuan DIN 1X1 ISO U(A)-P-D-L series products integrate multi-channel high isolation DC-DC power supply, analog signal isolation amplification and conversion circuit, programmable MCU, signal isolation control circuit, etc.It is especially suitable for AD conversion and isolation transmission of industrial field analog signals, as well as occasions where fieldbus, Ethernet Internet of Things, PLC/DCS host computer collects and analyzes multi-channel sensor signals.The high-efficiency DC-DC isolated distributed power supply integrated in the product supplies power to the internal input conditioning circuit, micro-MCU AD conversion circuit and output signal isolation circuit respectively.The SMD process structure and new technology isolation measures enable the device to achieve: 3000VDC isolation between analog signal input and auxiliary power supply and PWM signal output, and can meet the requirements of industrial-grade wide temperature, humidity and vibration on-site harsh working environment.
