Hi guys, I hope you're all doing great This could be probably for Peter but most of you will know the answer so here it goes.
I have to drive some 24 VCC pneumatic electrovalves and I would like to use 7i72's outputs directly. Each valve consumes 400 mA and the 7i72 max current per output is 300 or 350 mA. But, the short circuit protection per output is triggered at 800 mA. So I was thinking in two possible ways to drive the valves: 1- to accommodate one valve per output (without exceeding the 1.4 amps of max current per output chip) and hope the 400mA are not too much for the overcurrent monitoring. 2- to drive every valve with two consecutive outputs to divide the current in half so every output would only see 200 mA (again without exceeding the max current per output chip). What do you guys think? I'm trying to avoid to install any extra circuitry if possible. Thank you as always for your help! _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
