RNF22 power feed-in and error message module

24 V DC

Uin - 0,8 V

24 V DC

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.
