PC817 3.6-30V 2 Channel Optocoupler Isolation Board Voltage Converter Adapter Module Driver Photoelectric Isolated Module 817
Specificatii:
It can realize 3.3V or 5V control 3.3---30V voltage level interface, after the control
terminal input high level is turned on, the controlled terminal will also conduct to
the ground, and the port changes from the original high level to the low level. For
the friend of the single-chip or PLC, it is only necessary to judge when the output
port is low.
The photoelectric isolation has strong anti-interference ability, and the
combination control of many different devices can be realized later, such as triode,
MOS tube, and small power relay module.
If it is a pulse signal, please note that the limit of 817 is below 3KHZ. If the control
signal is greater than 3KHZ, please do not use this module, it will not work properly.
Parameter:
1, the drive terminal signal voltage: 3.3-24V
2, the output voltage range: 3.3-30V (output current depends on the specific
situation, but the maximum is not 10MA, the total power is certain, the voltage and
current are inversely proportional)
3, through the jumper cap can achieve whether the output is high potential output
or low output.
4, the board above 2 / 4 817 are independent, can achieve simultaneous control of
different voltages, etc.
5: board size: length: 48mm; width: 38mm; long side hole distance: 42mm; wide
side hole distance: 32mm
