Allen-Bradley 855T-B10TL6 Stack Light Blue LED 120 VAC

Allen-Bradley 855T-B10TL6 is a blue, steady-LED stack light module from Rockwell Automation’s 855T Control Tower Stack Lights family, designed for 5-module stacks. It operates on 120 VAC (±10%), 60 Hz, and includes the bulb in the package, making it a ready-to-install status indicator for automation equipment. The unit mounts on standard configurations with either a surface-mount base or a 10 cm aluminum pole base, providing bright, unambiguous signaling for machine status, process readiness, or fault conditions in control panels and production lines. In typical use, the blue LED conveys information/state within a color-coded signaling scheme, helping operators quickly assess line conditions in busy industrial environments.
