Industrial 1LS2004 Panel Plate Indicator Light Assembly Frequency Meter

Reliance Industrial’s 1LS2004 Panel Plate Indicator Light Assembly Frequency Meter is a panel-mount module that merges an indicator light with a built‑in frequency meter for on‑panel visibility. The model 1LS2004, including the RUN IET variant, is designed for installation on a control panel plate where both status indication and frequency readings are needed in a compact form. As a panel plate indicator light assembly with an integrated frequency meter, it provides a visual signal while displaying the measured frequency, enabling operators to quickly assess operating conditions without switching to separate instruments. This Reliance component belongs to a heritage line of panel‑mounted indicators used in industrial automation and electrical distribution, where space efficiency and readable data on the front face are important. The RUN IET designation indicates a specific variant within the 1LS2004 family, aligning with standard practices of labelable faceplates and compatible mounting arrangements used in industrial panels. In summary, the 1LS2004 combines two essential functions—visual indication and frequency measurement—into a single, panel-mounted module suitable for control systems that require readily visible status and frequency data in one compact package.
