Allen-Bradley 856T-B24QD5C 70mm Four Color Stack Light

The Allen-Bradley 856T-B24QD5C is a 70 mm stack light base from the 856T Control Tower family that operates on 24V AC/DC and provides four independent signal circuits in a black housing with a cap included. This preassembled base is configured without a network option and uses a 5‑pin M12 connector along with an M30 mounting thread, enabling straightforward installation and reliable panel or pole mounting for up to four stacked lights or sound modules. With four circuits, the unit supports multiple colors or signal states in a single stack and is designed to be expanded by adding compatible 856T light modules, delivering a compact, scalable visual indication solution for machines and processes. Power is supplied via 24V AC/DC, and the base is intended for industrial environments where fast status recognition is critical; the cap included helps complete a color-ready assembly for quick identification.
