Allen-Bradley B10ME722 120V Solid State Relay

The Allen-Bradley 855-series B10ME722 panel-mount signaling device is a 120 V AC visual alert designed for industrial panels and equipment. Available in variants such as 855PS-B10ME722 (Panel Mount Strobe) and 855PB-B10ME722 (Panel Mount Beacon), it installs in a 45 mm-diameter enclosure using a 22.5 mm round mounting hole for quick, secure panel integration. The unit operates from a nominal 120 V AC supply (plus/minus tolerance depending on region) and is intended to provide immediate, conspicuous signaling in noisy environments where audible alarms may be unreliable. Depending on the exact SKU, configurations can include a clear lens with a black housing and, in some cases, selectable steady or flashing LED operation for flexible signaling needs. Typical applications include machine status indication, process or safety alerts on control panels, and general signaling across manufacturing lines, packaging lines, and other industrial environments where compact, visible alerts are essential. As part of Allen-Bradley’s signaling lineup, these panel-mount beacons and strobes are crafted for straightforward installation in control cabinets or directly on equipment enclosures, delivering a reliable, low-maintenance visual cue without requiring complex wiring or external relays.
