Limit Switches for the Compax

The Compax Controllers expects to see normally closed end of travel and Home switches. The programmable I/O works the same way. This feature cannot be changed. Normally closed switches are the only compatible switch that may be used with the Compax.

The newer Compax3 can be used with normally open or closed sensors, both NPN and PNP. See help file, search x12 for details.
