This module is used when it is necessary to isolate the control in actual work and voltage conversion.It can realize 3.3V 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. The latter 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 below 4KHZ. If the control signal is greater than 4KHZ, please do not use this module, it will not work properly.
Overall, the 817 optocoupler 2-way voltage isolation board is a device with a simple appearance and excellent texture. Its details are handled very delicately, and each part plays an important role. Both in appearance and function, it can meet the needs of voltage control transfer and driving photoelectric isolation.
