  • Page 3: Overview

    Overview Description In conjunction with a 24 V power supply, the selectivity module is used to distribute the load current across several branches and to monitor the individual currents in these branches. Faults in the individual branches caused by overload or short-circuit are detected and selectively switched off, so that the fault does not impact the other load circuits.

    For information on actuating the potentiometer (screwdriver, torque), see Figure 2-2 Terminal data (Page 13). Note For SITOP PSE200U, the actual output current of a branch can be determined by measuring ⑦ the voltage at measuring point "MP" with respect to the "0 V" terminal. A measured voltage of 1 V corresponds to an output current of 1 A.
