How to Control Digital Output using NORVI ESP32 Based Industrial Controller | Open Collector DO |

In this video, we demonstrate how to use the NORVI ESP32-based industrial controller to control digital equipment, such as an LED. This controller features two transistor outputs that utilize reverse logic (open collector). When the output is turned on, the voltage will drop to 0V, keeping the LED off. When the output is turned off, the voltage will rise, turning the LED on.

For this setup, we used a 24V DC power supply, as LEDs in industrial environments are designed to handle this voltage. The code to control the outputs is available in our GitHub repository (link below).

Additionally, you can replace the LED with a relay to control heavier equipment, making this controller versatile for various industrial automation tasks.
