HALJIA PC817 4 Channel Optocoupler Isolation Board Voltage Control Converter Adapter Module 3.6 30V Driver Photoelectric Isolated PC 817

This module is used when it comes to the need for isolation control and voltage conversion. Drive port signal voltage: 3.6-24V. Output port 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 3.6-24V voltage level. 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.
