SITOP SEL1400 EX 10 A selectivity module 8-channel with limiting characteristic input: 24 V DC/60 A output: 24 V DC/8x 10 A threshold adjustable 2-10 A with monitoring interface The selectivity module SITOP SEL1400 is the optimum expansion for all 24 V power supplies in order to distribute the load current to several current branches and monitor these. Overloads and short-circuits in one or more branches are detected reliably. Brief current peaks, e.g. due to high starting current, are permitted by the electronics. Branches with longer overloads are deenergized. This is ensured even with high-impedance lines and creeping short-circuits. The intact branches are supplied, thus minimizing system downtimes. Signaling of the faulty branch takes place via LEDs on the device as well as via a common signaling contact or diagnostics monitor.
