The ABB CL2‑507G is a compact illuminated pilot light designed for panel mounting in industrial and commercial control systems. It features an integrated LED light source and a green indicator lens that provides clear visual status signaling without the need for a replaceable bulb. The pilot light is built in a rugged compact housing suitable for demanding environments and supports both AC and DC supply within its rated voltage range. Its standard 22 mm panel cut‑out and screw terminals make it easy to install in control panels, machine interfaces, and operator stations. The device is suitable for a wide range of electrical installations where visual indication is required.
