PC817 Optocoupler Isolation Board
When it is important to isolate the control in real work and voltage conversion, this Optocoupler Isolation Board is employed. It is capable of 3.3V or 5V control. When the control terminal input high level is powered on, the controlled terminal will also conduct to ground, and the port will change from the original high level to the low level. It is just essential for the single-chip or PLC buddy to assess whether the output port is low.
The Optocoupler Isolation Board has a high anti-interference capability, and later on, the combination control of several different devices, such as a triode, MOS tube, and tiny power relay module, may be realized. If it’s a pulse signal, keep in mind that 817 has a frequency limit of less than 3KHz. If the control signal is higher than 3KHZ, this module will not function properly.
Key Product Features:
- The Optocoupler Isolation Board can do low-level driving as well as voltage conversion.
- The MCU’s IO voltage can be graded using this module to achieve an isolated drive between various levels of voltage.
- By selecting the jumper cap of each channel, you can get individual control over whether it is coupled with the input.
- The jumper cap is shorted so that the output terminal’s negative terminal is linked to the power supply’s negative pole.
- Each channel has its own power indication, which may be directly controlled by the MCU’s IO port.
- The input terminal is 5V high, and a current of 3-5MA can be driven.
- MCU output power to power the motor when an inductive device, such as a motor, is isolated, anti-interference safeguards the MCU’s circuit.
- The single-chip microcomputer’s output level is low, and the driving power of the driven module is high. For example, for level matching, some PLC input should have 24V voltage and can be converted by this module.
- The input signal of the inverter can be inverted.
Applications:
- Used for high voltage detection, such as when a sensor’s output signal level is 12V. The single chip has a voltage of 5V.
- This module can be used to detect isolation.
