3xEL357N-C Optocoupler Module Signal Level Conversion 5V Input 3.3V NPN Output
Description:
Mini optocoupler , signal level conversion module.
Suitable for general level conversion.
5V side can use long wire connect with button, the output side is connected to the MCU IO pin.
The highest signal frequency is 2KHz.
With input signal indicator, connection protection for and current limiting resistor.
The
output end is an optocoupler triode, NPN output ; The output terminal
has current limiting resistance, and can not directly drive the relay
module and other high current equipment.
