SITOP SEL1200 & SEL1400
Selectivity modules for optimal and reliable protection for 24-V loads
The selectivity modules Sitop SEL1200 and Sitop SEL1400 separate 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.
