PoLabs THC Hookup Question


I have a PoLabs THC. When I hook up the the THC up, Down, and Arc Ok signals; will I need the resistors referenced in the PROMA 150 hookup? The specs reference a solid state relay output with a max load of 200Ma, and a R on < .6 Ohms (which is a little different than the Proma 150).

FYI I will be using a Hypertherm 45 XP.


Thank you for the advice.

for the PoLabs THC you will not require the resistor as they are giving the 6 V to 36 V to the common input
