Smart Current Driver 9000Ex-31/ Ex-32
9000Ex-31 and 9000Ex-32 are single-channel Smart Current Drivers that provide a galvanically isolated 4–20 mA signal to the hazardous area, corresponding to a 4–20 mA input signal from the safe area. They repeat the current signal in another floating circuit to drive a hazardous area load, using isolating transformers that provide galvanic isolation. The Smart Current Driver operates SMART I/P converters, electric valves, and positioners in hazardous areas. It
features high output capacity combined with a low voltage drop across its input terminals.
