AOICRIE 6pcs PC817 1 Channel Optocoupler Isolation Module 1CH 3-5V 12V 24V Photoelectric Isolator PNP NPN Signal Converter Rail Holder PLC Drive Motor Board

1-Channel PC817 optocoupler isolation module adopts 5.0 pitch screw terminals for convenient wiring. 1-way 817 optocoupler drive terminal input signal voltage: DC 3V-5V/12V/24V (optional); Output signal voltage: wide voltage suitable for DC1.8V-24V. The 1-way optocoupler isolation module is suitable for isolation when the output level of the single-chip microcomputer is used to drive inductive components such as motors, and anti-interference protects some circuits of the single-chip microcomputer. PC817 1 channel way optocoupler isolation board are good as the level converter(NPN-PNP, PNP-NPN), and can also be used to input a signal to MCU in isolation or MCU control another device in isolation. Photoelectric isolator rail holder PLC drive motor board output level of the single-chip microcomputer is low, and the driving voltage of the driven module is high for level matching.
