The selectivity module SITOP SEL1200 separates the 24 V output of a power supply into eight different load circuits. Thanks to the isolation and the electronic current monitoring on each circuit, the power supply remains stable in every other circuit even if, for example, a critical overload or short circuit occurs in a circuit due to a defective consumer unit. A special feature of these new modules is their diagnostic ability. If a load circuit is switched off due to a defect, the relevant warning LED (light-emitting diode) lights up and the reason for the switch-off is reported via a digital input to the controller. Similarly, the user receives up-to-date information on the current power consumption.
