The Schneider Electric XB5KSB is a Harmony XB5 complete buzzer with a dark grey plastic bezel and black cap, rated 24 V AC/DC with a continuous or intermittent tone.

Selection Notes

At 24 V AC/DC with a draw under 28 mA, the XB5KSB wires directly to a PLC digital output or 24 V control transformer, unlike the 230...240 V XB5KSM variant, which needs mains-level wiring. It omits the integral lamp of the XB5KS2 illuminated-buzzer variants, so pick it when only an audible signal is needed and panel space or wiring should stay simple. The Class II double-insulated construction removes the need for a separate protective-earth terminal on the device itself.
