Frequently Asked Questions
Q: What is the purpose of the Comimark 4-Channel Opto-Isolator Module?A: The Comimark 4-Channel Opto-Isolator Module is designed to electrically isolate a low-voltage microcontroller from high-voltage or noisy systems. This isolation helps prevent electromagnetic interference and enables safe control of high voltage devices.
Q: Can this module be used with different voltage levels?A: Yes, this module can be used with various voltage levels. It is suitable for controlling high voltage systems up to 24V while being controlled by low voltage signals from microcontrollers operating at 3.3V or 5V.
Q: How does the TLP281 optoisolator work in this module?A: The TLP281 optoisolator in the module uses built-in LEDs and photodiodes to transfer signals from the low-voltage side to the high-voltage side without direct electrical connection, allowing for safe signal transmission and logic replication.
Q: What are the output capabilities of this opto-isolator module?A: The module features four output channels (OUT1, OUT2, OUT3, OUT4), capable of handling a maximum absorption current of 500mA, which corresponds to the highest voltage (HVCC) divided by 5.1k ohms.
Q: Is this module suitable for noisy circuits?A: Yes, this module is excellent for use in noisy circuits, as it provides electrical isolation that helps prevent signal interference and ensures reliable performance when controlling motors or servos in high-power applications.
