Static Controls 4003-RT Stack Light Red Yellow Green 24VDC

Static Controls 4003-RT Stack Light Red-Yellow-Green 24VDC is a three-color indicator module that provides red, yellow, and green illumination from a 24 VDC supply. Designed for industrial automation, it serves as a compact, in‑panel status indicator on machines, conveyors, and control panels, signaling stop (red), caution (yellow), and go (green) at a glance. The unit consolidates three signaling colors into a single stack-light housing, enabling multi‑state indication without mounting multiple separate indicators. It is intended for use in 24 VDC control circuits common to factory automation, PLC I/O networks, and machine controls, and it supports independent energization of each color segment for flexible signaling schemes. Typical applications include equipment fault or alarm signaling, process or cycle status, and operator alerts in manufacturing, packaging, and material handling environments. Because the Red-Yellow-Green colors are widely recognized in industrial signaling, the 4003-RT helps operators quickly assess line conditions from a distance. The compact, modular design supports straightforward integration into existing control panels.
