Specification:
1. Driving Terminal Port Signal Voltage:3.3-24V
2. Output Port Voltage Port:3.3-30V
3. Output current depends on the specificsituation, but the maximum is not 10mA the total power is certain, the voltage andcurrent are inversely proportional
4. Through the jumper cap can achieve whether the output is high potential outputor low output
5. Onboard 4-Channel 817 are Independent, which can achieve different voltage control at the same time

Note:
If it is pulse signal, please note that the limit of 817 is below 3Khz. If the controlsignal is greater than 3Khz, please do not use this module, it will not work properly

Application:
The output level of the single chip microcomputer is low, and the driving voltage of the driven module is high, for level matching, for example, some PLC inputshould have 24V voltage and can be converted by this module.

Package Included:
2 x PC817 4 Channel Optocoupler Isolation Board
1 x 24AWG Wire
