1 Inputs are optically isolated. They require 24 VDC at 12.5 mA or dry-contact closure at 8 mA.
2 Outputs are optically isolated, open-collector transistors. The maximum rating is 24 VDC at 10 mA.
3 Although the plasma power supply has output capability, it is normally used solely as an input.
4 CNC +24 VDC provides 24 VDC at 200 mA maximum. A jumper is required on J17 to use 24 V power.
5 Shield ohmic contact is used to interface to plasma interface boards that have their own ohmic contact
circuit. (See How to use ohmic contact sense on page 182.)
