Schneider Electric XVUC21B Harmony XVU Base Unit with Top Cover Black 60 mm 24 V Signal Tower

The Schneider Electric XVUC21B is a Harmony XVU base unit with top cover in black, the foundation module that a customer stacks LED, buzzer or sound units onto to build a complete 60 mm modular tower light. It is rated 24 V AC/DC -15...+10 % and carries an IP65 degree of protection for operation in dusty or wash-down environments.

Selection Notes

Choose the black XVUC21B to match the housing colour of the LED and buzzer units ordered for the same tower, since Harmony XVU bases, lenses and covers are sold as separate colour-matched parts rather than a single pre-assembled stack. At 24 V AC/DC -15...+10 %, it shares the same control-circuit supply as the rest of a 24 V automation panel, keeping the tower light on one low-voltage feed. Up to 5 indicator units can be stacked on this base before the fixing mode and overall tower weight need to be rechecked against the mounting tube or bracket.

Applications

Harmony XVU modular tower lights are specified on automotive assembly lines, packaging machines and machine tools, wherever a technician needs to see a machine's run, stop or fault state from across the floor without walking up to a control panel. The modular stacking design lets a maintenance team swap a single failed unit instead of replacing the whole tower.
