Field of application

The RNF22 is a power and error message module that provides a redundant 24 VDC supply voltage to the DIN rail interface bus connector system for safe operations in hazardous areas. Intelligent error diagnostics alert of power supply failure, NAMUR group error messages or fuse error via a relay contact and a flashing LED. The compact interface module is protected against overvoltage and reverse polarity via diode decoupling.

  • Power and error message module for safe and reliable operations in hazardous areas

  • Single or redundant 24 VDC supply voltage, up to 3.75 A supply current

  • Relay output for error message

  • Group error evaluation of connected NAMUR isolating amplifiers (RLN22)

  • Activation/deactivation of group error detection via DIP switch

  • Ambient temperature range: –20 to 60 °C (–4 to 140 °F)

Benefits

  • Safe and reliable 24 VDC interface power supply, single or redundant

  • Intelligent diagnostics built-in: power supply failure or fuse error

  • Quick and easy wiring with plug-in terminals

  • Compact housing: 17.5 mm (0.69 in) for efficient use of space in control cabinets
