8 channel optocoupler isolation board is used when it comes to the need for isolation control and voltage conversion. specific situation but the maximum does not exceed 10MA, the total power is constant, the voltage and current are inversely proportional) 8-way 817 optocoupler drive terminal signal voltage: 3.6-24V. Output terminal voltage range: 3.6-30V (output current depends on the 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 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.
