Active barrier Endress+Hauser RN22-8L1A
The 1-channel active barrier RN22-8L1A from Endress+Hauser is used for the transmission and electric isolation of 0/4...20 mA signals. The device has an active/passive current input to which a 2- or 4-loop signal conditioner can be connected directly. The device output can be operated actively or passively. In addition, HART communication signals are transmitted bidirectionally from the device. Connection lugs for connecting HART communicators are integrated in the front of the device. The RN22-8L1A supply isolator from Endress+Hause is intrinsically safe and suitable for use in potentially explosive atmospheres.
