![]() ![]() ![]() ![]() If you power the board by 24V you get all prevoius + the 3 Relays will work as they need 24V. "PWM 0-10V" terminal will be outputting 0-10V. If you power the board by 12V you get 5V output, power for your inputs and PWM signal. Manual says 12-24 which is not the whole explanations. The intended use is the "12V-24V Power input connection" (on image marked as 24V). Obviously this is not the intended use but it works fine. If you need Inputs (no PWM no Relays) and you have only 5V you can connect them to "5V out" connection. All you need to do is set you limit switch Active low in Mach3 as you do not have any signal input. if you need only to power outputs (for motor drivers) it will happily work from USB connector. In reality it might depends on what you need. In short: power the board by 24V and USB connection and it will all work. This board needs two power sources as they claim that isolating the digital from analogue part of the board is great idea. ![]()
