MINI MCR-SL-NAM-2RNO - Switching amplifier

Configurable NAMUR switching amplifier for proximity sensors, floating switching contacts and switching contacts with resistance circuit. On the output side 2 N/O contact, with screw connection

  • Floating contacts and contacts with resistance circuit can be connected
  • Power supply possible via the foot element (TBUS)
  • Highly compact isolation amplifier for electrical isolation, amplification, and duplication of proximity sensor signals
  • For proximity sensors according to IEC 60947-5-6 and EN 50227
  • Second output can be used as a duplicator or error signaling output
  • Error indication via diagnostic LED and analog signal
  • N/O contacts at output
  • Input and output signals can be configured via DIP switches
  • Operating current/closed circuit current switch-over (inverted switching behavior)
