Allen-Bradley 855T-B24TL5

The Allen-Bradley 855T-B24TL5 is a 70 mm amber LED stack-light module for control panels, featuring a steady LED indicator housed in a black 70 mm enclosure. It runs on 24 V AC/DC (±10%), delivering continuous amber illumination with a LED life rating of up to 100,000 hours and a light output of 1,400–3,550 millicandelas. The module draws about 29 mA at 24 V and supports up to 3 mA of leakage current from solid-state outputs. Built for industrial environments, it carries IP65 and NEMA 4X protection, uses a polycarbonate housing, and has a 70 mm outer diameter suitable for stacking with other 855T modules. Mounting options include surface-base installations or a 10 cm aluminum pole base; shock ratings up to 35 G and vibration around 0.75 G are specified for base configurations. Operating temperature ranges from -25 °C to storage at -40 °C. Recommended wire size is 0.5 mm² and terminal torque about 0.8 Nm. The 855T-B24TL5 is discontinued as of October 1, 2019, with a functional replacement in the 856T-BT5 family, and it is manufactured in Austria by Allen-Bradley (Rockwell Automation).
