Hypertherm XPR460 - Pinouts for the Discrete Cable for the Expansion PCB

3 Outputs are optically isolated, open-collector transistors. The maximum rating is 24 VDC at 10 mA.
4 Although the plasma power supply has output capability, it is usually used only as an input.
5 CNC +24 VDC provides 24 VDC at 200 mA maximum. A jumper is necessary on J17 to use 24 V power.

1 Outputs are optically isolated, open-collector transistors. The maximum rating is 24 VDC at 10 mA.
2 Shield ohmic contact is used as an input into an ohmic contact circuit (with either the XPR internal circuit or a customer-supplied circuit) to
sense when the torch shield has touched the workpiece. Refer to Use ohmic contact sense on page 198.
