Allen-Bradley 855E-24TL4 Indicator Light

Allen-Bradley 855E-24TL4 is a 50 mm control tower stack light module designed to provide a clear, high-visibility status indicator on industrial control panels. It features a red, steady-state LED in a socket-mount LED module and is specified for 24 V AC/DC full-voltage operation. As part of the 855E signaling family, the TL designation identifies a steady socket-mount LED lamp module, with color code 4 corresponding to red. The 50 mm tower format is compatible with standard 50 mm control-tower bases and stack-light assemblies, enabling straightforward integration into multi-light stacks for immediate process signaling. Typical applications include signaling machine status in manufacturing and automation environments where quick, at-a-glance visibility is essential.
