MINI MCR-SL-UI-REL-SP - Limit value switch

MCR threshold value switch, with adjustable hysteresis and delay time, with spring-cage connection. Replacement part: 2902035 MINI MCR-2-UI-REL-PT.

  • Power supply possible via the foot element (TBUS)
  • Highly-compact threshold value switch for switching analog limit values
  • Status and error indication via two diagnostic LEDs
  • Changeover contact relay at the output
  • 3-way isolation
  • Limit value can be freely adjusted via potentiometer on the front
  • Input signal, hysteresis, and delay time can be configured via DIP switches
  • Operating current/closed circuit current switch-over
