PC817 4 Channel Isolation Board Voltage Converter Adapter Module 3.6-30V Driver Poelectric Isolated Module PC 817

Brief descrtion: When encountering the need for isolation control and voltage conversion in actual work, this module will be used. It can realize the interface of 3.3V or 5V to control the voltage level of 3.3---30V. After the control terminal input high level is turned on, The controlled terminal will also be connected to the ground, and the port will change from the high level to low level. For friends of MCU or PLC, Just judge when the output port is low level. The photoelectric isolation has strong anti-interference ability, and it can realize the combined control of many different devices, such as triode, MOS tube, Low-power relay modules, etc. If it is a pulse signal, please note that the limit of 817 is below 3KHZ. Please do not use control signals greater than 3KHZ. Using this module will not work properly. Module parameters: 1. Signal voltage at the drive end: 3.3-24V 2. Output voltage range: 3.3-30V (The output current depends on the specific situation but the maximum is not 10MA, the total power must be Voltage and current are inly proportional) 3. The jumper cap can realize whether the output terminal is high potential output or pull low output. 4. The 2 channels/4 channels 817 on the board are independent, which can realize the simultaneous control of different voltages, etc. 2 Way Module Size: 4 Way Module Size: Schematic diagram： Feature: 1. It can realize low-level drive high-level and realize voltage conversion. 2. Use this module to convert the IO voltage of the single-ch microcomputer to achieve isolated drive between different voltage levels. 3. Through the selection of jumper caps for each channel, it can be individually controlled whether to share the ground with the input. The jumper cap is short-circuited as the negative output terminal Connect with the negative pole of the power supply (G in the figure). 4. Each channel has an independent power indicator light, which can be directly driven after being pulled up by the IO port of the microcontroller. Input 5V high level, 3-5MA The current can be driven. Application: 1 The output level of the single-ch microcomputer is used for isolation when driving motors and inductive components such as motors. road. 2 The output level of the single-ch microcomputer is low, and the driving voltage of the driven module is high for level matching. For example, some PLC inputs require 24V power. The preure can be converted with this module. 3 Used for inverter, can invert the input signal and output. 4 Used for high voltage detection, for example: the output signal level of a r is 12V and the voltage of the single-ch microcomputer is 5V. This mode can be used Block to isolate the detection. Guāng ǒu 2/5000
