The PC817 Optocoupler Isolation Board used when it comes to the need for isolation control and voltage conversion.
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.
Through the jumper cap can achieve whether the output is high potential output or low output.The 4th and 817 on the board are independent, which can realize simultaneous control of different voltages, etc.
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.
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.
Description
Parameter
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)
Whether the output is a high potential output or a low potential can be realized by a jumper cap.
The 4 channels 817 are separated., can achieve simultaneous control of different voltages, etc.
Board size: 48mm x 38mm (length and width);
long side hole distance: 42mm;
wide side hole distance: 32mm
Package Inluded:
4 * PC817 8-Channel Optocoupler Isolation Board
