The Allen-Bradley 855PC-B24ME322 is a panel-mounted sounder with LED beacon, featuring a green lens for clear visual signaling in control panels. It is powered from 24 V AC/DC (±10%), designed for 50/60 Hz operation, and mounts in a 45 mm opening with a 22.5 mm mounting hole; the housing is black to contrast with the green lens. This light-and-sound assembly provides audible alerts paired with a visual beacon, making it suitable for machine alarms, process indicators, and safety signaling within industrial control systems.
