2 Function

The active barrier galvanically separates and supplies 4 to 20 mA signal cir-

cuits. At the current input transmitters are connected, an additional power

supply is therefore not required. A current signal is available at the output

(active output ) for connection to further instrumentation. Bi-directional

HART

-communication with SMART transmitters is possible using the built-

in communication sockets (with resistance R = 250 Ω).
