2Pcs PC817 8 Channel Optocoupler Isolation Board 3.6-30V Driver Photoelectric Isolated Module Voltage Converter Adapter Module

It can realize low level driving high level and realize voltage conversion using this module, the IO voltage of the MCU can be graded to achieve isolated drive between different voltage levels Through the selection of the jumper cap of each channel, it is possible to achieve separate control whether it is shared with the input.The jumper cap is shorted so that the negative terminal of the output terminal is connected to the negative pole of the powersupply(Gin the figure) Each channel has an independent power indicator， which can be directly driven by the IO port of the MCU.The input terminal is5V high, and the 3-5MA current can be driven APPLICATION： MCU output level To drive the motor When the inductive device such as the motor is isolated, anti-interference protects the circuit of the MCU The output level of the single-chip microcomputer is low， and the driving voltage of the driven module is high For level matching, for example, some PLC input should have 24V voltage and can be converted by this module For the inverter, the input signal can be inverted Used for high voltage detection, for example：the output signal level of a sensor is12V The voltage of the single chipis5V.This module can be used for isolation detection Package include: 2 x PC817 8 channel optocoupler isolation board NOTE: The input port is shared with GND The output ports are independent of each other It is optocoupler output.V and G will be connected after input valid signa in input port

• 8 channel optocoupler isolation board is used when it comes to the need for isolation control and voltage conversion.
• 8-way 817 optocoupler drive terminal signal voltage: 3.6-24V. Output terminal voltage range: 3.6-30V (output current depends on the specific situation but the maximum does not exceed 10MA, the total power is constant, the voltage and current are inversely proportional)
• It can realize 3.3V or 5V to control the interface of 3.6-30V voltage . After the control terminal is turned on, the controlled terminal will also be turned on.
• Photoelectric isolation has strong anti-interference ability. It can drive high-power triodes, MOS tubes and other applications that require high-voltage driving, and can also directly drive low-power 24V relays.
• If it is a pulse signal, please note that the limit of 817 is 4KHZ or less. If the control signal is greater than 4KHZ, please do not use this module, it will not work properly.
