The Allen-Bradley 855E-24TL4 is a 50 mm Control Tower Stack Light module that operates on 24V AC/DC Full Voltage and uses a red steady LED with a socket-mount light head, designed for integration into 855E signaling towers. As part of the 855E family, this module supports easy wiring via top-mounted terminal blocks for tool-free installation. It functions as a compact, highly visible status indicator in industrial automation, providing a single-color red signal in control towers and signaling assemblies where clear, immediate indication of machine state is required.
