4-Channel Optocoupler Module

The 4-channel optocoupler isolation module features four independent ports for control signal isolation. Allows for interfacing devices to a microcontroller or other device with full isolation between the input and output for control at different voltage levels. Optoisoloation is useful in noisy or when different control voltages are needed for devices such as relays, motors, or other actuators.

Commonly used with 3D printers or CNC configurations (Smoothstepper) or other projects which require voltage level conversion or voltage isolation to reduce noise, then this board is what you need.

Product Details

Driving Port (Input): 3.6V to 24V DC
Control Port (Output): 3.6V to 30V DC

Note: The Ground (Gnd) signals on the input side are all common (tied together). The output grounds can be connected together (with the Red jumper installed), or completely isolated (Red jumper removed).
