Hi, I'm thinking of adding a powermax 45 plasma torch to my current setup which includes pmdx 126 and ess. I will eventually be using a torch height controller THC. The plasma cutter requires a dry contact to trigger to arc (18VDC Normal Open on the plasma end, shot to start the arc).
To trigger the plasma would the PMDX-105 connected to a standard output be a good choice as it provides additional layer of optical isolation and has a fast response time of 2 ms? Or would I be better off using the relay on the pmdx 126 board?
