H-Bridge and lab view
We want to use 4 high power fets to drive a DC motor. Can we connect them directly to an NI-9474 (sourcing digital output module), or should we add some isolation between (like an opto-isolator board)? Does anyone sell pre-maid drive boards with isolation? I know test boards are available through ST and Allegro that have a fet board and drive board for evaluation, but we really want to avoid using relays with this set up. It's 50-100A paek from the test motor and have to run 12 to 48VDC through them. Then have to control them with lab view and some output module.
