Bulletin 855E 50mm Control Tower™ Stack Lights
The 855E 50mm Control Tower Stack Light is the essence of Allen-Bradley application-driven design. This cost-effective system is small and efficient, offering greater flexibility, reliability, and increased productivity. Like other Allen-Bradley products, it is designed to reduce the time and cost of installation, configuration, maintenance and repair, lowering your total cost of ownership.

Watertight Sound Modules
Rockwell Automation is introducing new 855E 50mm ultra-high output sound modules that focus on performance. This new addition to the 855E 50mm Control Tower Stack Light is packaged in a watertight housing with a sound output of 103dB at a distance of 1 meter. The 855E products were designed to offer unmatched status indication performance in a variety of applications ranging from dry packaging, to food processing, to clean-room applications. The ultra-bright light modules and the new ultra-loud sound modules make the 855E offering the best choice for audible and visual status indication in the slim-line stack light market.
- Reliable Ultra-High Output Sound — Sound output of 103dB at a distance of 1 meter. This is approximately 15-20% louder than other sound modules offered in a comparable size product.
- Easy Volume Adjustment — Because the sound output is so high, Allen-Bradley offers a dipswitch with a reduced volume setting. This dipswitch allows easy adjustment of the volume.
- Flexibility — The tone selection feature offers continuous or pulsing tone choices. The single-circuit module will signal one condition and the two-sound circuit module is capable of signaling two different conditions in one stack, each with a different tone.
