Frequently asked questions
Can it connect directly to a 3.3 V microcontroller?
The output is at 5 V logic level. For a 3.3 V board, use a level shifter or confirm the output level suits your board before connecting.
How do I wire the input channels?
Refer to the silk-screen labels on the module for the channel input, common and power pins. Confirm the 24 V input polarity and supply connections before powering the module.
