Power Supply
RN 221 N power supply and active barrier galvanically separates 4-20 mA signal circuits. The unit has an active current input to which a transmitter can be connected. A current signal is available at the output (passive output) for connection to further instrumentation. Bi-directional HART communication with smart transmitters is possible using the built-in communication sockets (resistance R=250 Ohm). The device includes sensor monitoring with early-warning system, and manual or automatic reset of the relay contact.
