Allen-Bradley 855T-B00XN6 Stacklight Base

Allen-Bradley 855T-B00XN6 Stacklight Base is the 70 mm Control Tower Stack Light base that serves as the foundational chassis for the 855T signaling family. It is designed to accept up to five light modules, enabling configurations from a single module to multi-stage indicators, including combinations of lamps and sound modules where applicable. The base supports steady-function lighting with input voltages from 0 to 250 V AC/DC, compatible with LED or incandescent lamp modules, making it suitable for standard industrial signaling on control panels and machinery. Mounting options include a surface-mount base or a 10 cm aluminum pole base, offering flexible installation in tight enclosures or on equipment frames. The base construction incorporates polycarbonate components for the housing/interface assembly, aligning with other 855T stack-light components in terms of durability and electrical isolation. Notably, the B00XN6 designation identifies a base-only unit (no lamp module included), so you’ll pair it with your chosen light modules to complete the stack light assembly. In typical 70 mm stack-light configurations from Allen-Bradley, this base accommodates blue-lens modules and adheres to the established five-module stacking approach, helping operators convey status, fault, and process conditions clearly across automation lines.
