OVERVIEW Endress+Hauser RN221N-B1 Transmitter Supply The RN221N is a FM certified active intrinsically safe barrier with integral power supply for safe isolation of 4 to 20mA current circuits.Typically the RN221N is mounted in the non-hazardous area and the split between the supply voltage and the intrinsically safe voltage occurs in the device itself. The cables powered by the RN are then fed into the hazardous area where they power the two wire transmitter. The RN221N transmits the measured signal received from the hazardous area to the non-hazardous area equipment. HART signals are bi-directionally transmitted.
