ZkeeShop 2Pcs PC817 4 Channel Optocoupler Isolation Board

When encountering the need for isolation control and voltage conversion in actual work, this module will be used.

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 module, etc.

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,as it will not work properly.

It can realize 3.3V or 5V to control the interface of 3.6-24V voltage level. After the control terminal is turned on, the controlled terminal will also be turned on.

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)
