The SB3045 isolates and passes on a 4/20mA signal from a controller located in control station to drive a current-to-pressure (I/P) converter or any other load up to 600Ω in the field. It has a high output capability of 12V at 20mA combined with a low (6V) drop across the input terminals and excellent accuracy.
