Overview

The Federal Signal USI-120QC UniStat LED Status Indicator is a quad-color (Amber, Blue, Green, Red) signaling device designed for 120VAC industrial applications. This single-high indicator delivers clear, multi-state communication with four distinct colors, enabling operators to monitor equipment status, process conditions, or safety interlocks at a glance. The 50,000-hour vibration-resistant LED light source ensures long-term reliability in harsh environments, while the IP66-rated enclosure and Type 4X NEMA rating provide protection against dust, moisture, and corrosion. Installation is flexible with both surface mount and 3/4-inch NPT pipe mount options, allowing integration into existing control panels or piping systems. The USI-120QC is PLC compatible, simplifying connection to automation systems, and is UL and cUL listed for compliance with safety standards. With a compact design and durable construction, this indicator is ideal for indoor use where precise, color-coded status indication is critical. The quad-color capability reduces the need for multiple single-color indicators, streamlining system design and reducing installation complexity. Available in 24VDC and 120VAC variants, the USI-120QC is a versatile solution for facilities requiring reliable, high-visibility signaling in demanding industrial environments.
