NOYITO 1-Channel PC817 Optocoupler Isolation Module Optoelectronic Isolator Signal Isolation and Anti-Interference 3-5V 12V 24V (Pack of 2) (3-5V)

NOYITO 1-Channel PC817 Optocoupler Isolation module adopts 5.0 pitch screw terminals for easy wiring . The module can play the role of isolation when the output level of the single-chip microcomputer drives the inductive devices such as motors and motors, and protect part of the circuit of the single-chip microcomputer against interference
The module can be used for high-voltage detection. For example, if the output signal level of a sensor is 12V, and the voltage of the microcontroller is 5V, this module can be used for isolation detection.
The module can also be used for current amplification. For example, when the output current of the microcontroller is too small to drive certain circuits, this module can be used for amplification.
Input signal voltage: 3-5V / 12V / 24V (optional).
Output signal voltage: wide voltage, suitable for DC1.8 - 24V.

NOYITO PC817 4-Channel Optocoupler Isolation Board Voltage Converter Adapter Module 3.6-30V Driver Photoelectric Isolated Module

This module is used when it comes to the need for isolation control and voltage conversion.
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)
It 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.
Photoelectric isolation has strong anti-interference ability. It can drive high-power triodes, MOS tubes and other applications that require high-voltage driving, and can also directly drive low-power 24V relays.If it is a pulse signal, please note that the limit of 817 is 4KHZ or less. If the control signal is greater than 4KHZ, please do not use this module, it will not work properly.
