PC817 3.6-30V 2 4 Channel Isolation Board Voltage Converter Adapter Module Driver Poelectric Isolated Module 817-8 Channel

P roduct D escrtion

In actual work, I encountered the need for isolation control and voltage conversion At that time, this module will be used. Can achieve 3.3V or 5V control 3.6~24V voltage level interface,After the control terminal is turned on, the controlled terminal will also be turned on.The photoelectric isolation has strong anti-interference ability. It can drive high-power transistors behind, MOS tube and other occasions requiring high-voltage drive, can also directly drive small Power 24V relay works.

If it is a pulse signal, please note that the limit of 817 is 4KHZ or le Please do not use this module for control signals greater than 4KHZ, it will work Not working properly.

1. Signal voltage at the drive end: 3.6-24V.

2. Output voltage range: 3.6-30V (output current depends on specific conditions But the peak value is not 10MA, the total power must be the opposite of voltage and current Than).

3. The jumper cap can realize whether the output terminal is high-potential output or pulled low Output.

4. All 4 817 channels on the board are independent and can achieve different voltages Simultaneous control etc.

5. Board size: 4 channels 47*38mm hole spacing 41*32mm

2 way 38*29mm hole pitch 32*23mm.

P roduct F eatures

1. It can realize low level drive high level, realize voltage conversion.

2. Use this module to convert the IO voltage of the single-ch microcomputer. Achieve isolated drive between different voltage levels.

3. Through the selection of jumper caps for each channel, you can achieve individual control of whether Common ground with input. The jumper cap is shorted for the negative output terminal and the negative power supply Extremely common.

4. Each channel has an independent power indicator light which can be pulled up by the MCU IO port Direct drive. Input 5V high level, 3-5mA current is enough drive.

P roduct A pplications

1. When the single-ch microcomputer output level is used to drive inductive devices such as motors Isolation, anti-interference and protection of part of the single-ch circuit.

2. The output level of the single-ch microcomputer is low, and the driving voltage of the driven module is high.Level matching, for example, some PLC inputs require 24V voltage to use this Module conversion

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 MCU voltage is 5V, this module can be used to isolate and detect The voltage of 12V single-ch microcomputer is 5V, and this module can be used to isolate and detect.
