Overview
     SunYuan  DIN 1X1 ISO U(A)-P-D-L series products are programmable analog signal to PWM pulse width modulation high current control isolation transmitter newly developed by Sunyuan Technology, which can output 4-20mA/ 0-20mA/0-5V/0-10V and other analog signals are isolated and converted into PWM pulse width modulation power amplification control signals, and the PWM frequency programmable output is realized.The product is embedded with MCU single-chip AD input conversion control, and the output control design is divided into MOS tube open drain type (OD gate) passive PWM high current control output mode DIN 1X1 ISO U(A)-PD-L1 series and active PWM voltage pulse width control output mode DIN 1X1 ISO U(A)-PD-L2 series.The product adopts standard DIN35 rail installation method, low cost, small size, easy to use, and high reliability. It can be used for motor speed control, lighting dimming control, boiler temperature PWM precision control, etc., in rail transit, industrial control intelligence, robots, electric Automobiles, ship drives, automation equipment, CNC machine tools, energy-saving and environmental protection engineering, and energy-saving control of urban lighting in highway tunnels are widely used.
 
SunYuan  DIN 1X1 ISO U(A)-P-D-L1 series open-drain passive PWM high-current control output mode is mainly used in the load itself. The receiving port is an active receiving port. The receiving port is equipped with a pull-up voltage and a current-limiting resistor. It is required to connect to the control occasions where the transmitter current is drawn into the power distribution mode.When the drain of the MOS tube is open, the sink current can reach 0~1A, and the output voltage amplitude of the PWM pulse width signal is determined by the external pull-up voltage. Open-drain passive PWM output products can realize analog signal input/PWM output/auxiliary power 3000VDC, three isolation.
 
SunYuan  DIN 1X1 ISO U(A)-P-D-L2 series active PWM voltage pulse width control output mode can be used to directly drive high-power passive loads, such as stepper motors and precision temperature-controlled heaters, and the drive current can reach 0-1A , Has a strong load capacity.The amplitude of the PWM output voltage is determined by the power supply voltage of the module, so products with this output mode can only achieve isolation between 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. Need to choose the product corresponding to the output method.
 
 
SunYuan  DIN 1X1 ISO U(A)-P-D-L series products integrate multiple high-isolation DC-DC power supplies, analog signal isolation amplification and conversion circuits, programmable MCUs, signal isolation control circuits, etc. in the same module, especially suitable for industrial field simulation Signal AD conversion isolation transmission, and fieldbus, Ethernet Internet of Things, PLC/DCS host computer to multi-channel sensor signal acquisition and analysis occasions.The integrated high-efficiency DC-DC isolated distributed power supply inside the product separately supplies power to the internal input conditioning circuit, micro single-chip AD conversion circuit and output signal isolation circuit. 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 it can meet the requirements of industrial-grade harsh working environment with wide temperature, humidity and vibration.

Remarks:

Open-drain output means that the drain of the MOS tube is connected to the output. When the passive receiving port is used, a pull-up resistor needs to be connected to the power supply of the required voltage amplitude. The size of the pull-up resistor is selected according to the current size of the customer's own needs;RS232 communication is mainly to change the frequency. It can be connected to the RS232 interface of the computer, or you can add a chip to the USB interface to the computer. If you don't change the frequency of the PWM signal, you can leave it alone.
