The Endress+Hauser RN221N-B1 is an active barrier with an integrated transmitter power supply designed for the safe separation of 4 to 20 mA current signal circuits. This device provides galvanic isolation between the input and output circuits, making it ideal for removing large loop circuits and powering 2-wire transmitters in process control environments. Equipped with an intrinsically safe input option for hazardous locations, it supports bi-directional HART communication to transmit status information and sensor configurations smoothly from the field to control instrumentation. The Endress+Hauser RN221N-B1 features a compact 22.5 mm housing suited for standard top hat DIN rail mounting, ensuring efficient use of cabinet space across various industrial automation systems.
