Ok, But latching or not, the software that is running the machine will go into reset condition the second it receives an E-stop or limit switch touched, until someone physically pushes the reset button in the software, and then clicks on start again in the software. So regardless of weather the E-stop remains latched or not, The PDMX will not activate anything again as the software is in reset active mode? A latching circuit is adding another layer of buttons I have to press to get the machine started again.

What do you think about the load I was placing on the K2 relay? All i did was look at the rated Watts, or Amps per motor and figure out what that would be at 240 Volts ( 100% conversion) to guess the load at max drain for everything on? It says 10A max in the manual
