MACX MCR-SL-NAM-R-SP

MACX MCR-SL-NAM-R-SP - Isolation amplifier

NAMUR signal conditioner for operating proximity sensors and switches. The signals are transmitted to the control level via relay output (changeover contact). Line fault detection (LFD), 3-way electrical isolation, SIL 2, with Push-in connection.

  • Power supply and error indication possible via DIN rail connector
  • Installation in zone 2, protection type "n" (EN 60079-15) permitted
  • Up to SIL 2 in accordance with EN 61508
  • Line fault detection (LFD), can be activated/deactivated, error indicated by flashing red LED with de-excitation of output relay
  • Direction of operation can be selected (operating or closed circuit current behavior)
  • 3-way electrical isolation
  • LED indicators for supply voltage, switching state, and malfunction in accordance with NAMUR NE 44
  • Signal output relay (changeover contact)
  • Input for NAMUR proximity sensors (EN 60947-5-6), floating contacts or contacts with resistance circuit
