Alinan 4pcs 4CH Optocoupler PC817 4 Channel Isolation Board Voltage Converter Adapter Module 3.6-30V Driver Photoelectric Isolated Module-Fast Shipping

Description

Driving Port Signal Voltage: 3.6-24V; Output Port Voltage Port: 3.6-30V

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 will also be turned on.

Photoelectric isolation has strong anti-interference ability. Can drive big behindPower triodes, MOS tubes, etc., where high voltage driving is required, 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.

Through the jumper cap can achieve whether the output is high potential output or low 4th and 817 on the board are independent, which can realize simultaneous control of different voltages, etc.
