Eaton M22-L-G — M22 Green LED Indicator Light 24V

Green LED indicator light for Eaton M22 series. 22.5mm cutout, 24V AC/DC, IP67 front.

Common Applications

Illuminated indicator showing equipment running status. The green LED indicates power on, process running, or safe condition. Common on motor control centers, pump stations, and HVAC panels. The M22 series LED module accepts 12-30V AC/DC — compatible with most PLC and relay outputs without an external transformer. Rated for 100,000 hours LED life (11+ years continuous). The flat lens design sits flush with the panel for a clean, modern look.

This is a modular component. For a complete assembly, you may also need:

Installation Quick Reference

Panel cutout: 22.5mm. Insert from the front, secure with mounting nut.

LED module: Check the voltage rating matches your supply (typically 24V DC or 230V AC). Connect to PLC digital output or relay contact for status indication.

Color meaning (IEC 60204-1): Green = normal/running. Red = fault/danger. Yellow = warning/caution. Blue = mandatory action. White = neutral/general.

Troubleshooting

Light is dim or flickering

Check supply voltage matches the LED module rating. Low voltage causes dimming. If voltage is correct, the LED module is failing — replace it. LED modules have finite life (typically 50K-100K hours).

Light doesn't turn on

Verify voltage at the terminals with a multimeter. Check the PLC output or relay driving the light. LED modules are polarity-sensitive on DC circuits — try reversing the leads.
