Title: Max length for an e-stop run on the PMDX-126
Post by: trebuchetguy on April 25, 2022, 05:20:55 PM

What is the max length for the e-stop run on the PMDX-126? I'd like to put an e-stop for my mill on the other side of my shop; that might be about a 80 foot run.

Thanks!

With an 80 foot long cable there is a risk of electrical noise pickup causing false E-Stops. I would suggest that you have a relay near the PMDX-126 to connect in your E-Stop loop and arrange a 12 or 24 volt circuit to control the relay from across the room.
