The Allen-Bradley 855T-B24DN5 Stack Light is a 70 mm control-tower signaling module designed for compact, multi-light status indicators on industrial machinery. It features orange illumination with a 24 V AC/DC power requirement and uses a DN (steady incandescent) lamp configuration. This module is intended to be used as part of a stack with other 855T light modules to build clear, hierarchical machine signals for states such as run, stop, or fault in manufacturing environments.
