Safety Control Unit SF-C21


Enable flexible customization

The software provides highly flexible customization. You can create a logic of your own, change the input device types based on the preset logics, or customize logic data uploading from the SF-C21 main unit. Changing the auxiliary output settings, as well as setting the ON delay / OFF delay time and muting state holding time are all very easy as well. Created logics can be stored in a PC for convenient future use.
Settable items

  • Input device selection
  • Logic selection (up to three layers)
  • Auxiliary output settings [Linkage to control output (positive logic and negative logic), monitor output of safety input, reset trigger output, lockout output, etc.]
  • OFF delay time setting (0.0 to 60.0 sec, in 1/10 sec.)
