Eaton M22 blue indicator light.
常见应用
Blue = mandatory action per IEC 60204-1. Shows that operator intervention is required. Completes the full Eaton indicator set.
Research Notes
1. Overview
The Eaton M22-L-B (catalog 216775) is a 22.5 mm blue indicator (pilot) light for the M22 / RMQ-Titan system — a flush, illuminated status light (not a pushbutton), typically 24 V AC/DC. The M22-L family is the indicator-light line; B = blue. As with M22 modular parts, a complete indicator combines the lens/light head (M22-L-B) with a fixing adapter (M22-A) and an LED element (M22-LED-…). Blue conventionally signals a mandatory action / information / normal special state.
2. User Sentiment
M22/RMQ-Titan indicators are standard, robust panel status lights — valued for the clean modular system, bright LED elements, and matching the M22 pushbutton aesthetic. The practical point is modular assembly: order the correct lens color, LED voltage, and fixing adapter.
3. Real-World Applications
Panel/machine status indication — blue for information/mandatory-action or a defined special state, alongside M22 pushbuttons and other indicators on a control panel.
4. Technical Specifications
- Type: M22/RMQ-Titan indicator (pilot) light, 22.5 mm, flush — not a pushbutton
- Color: blue
- Voltage: 24 V AC/DC (LED element; confirm exact LED code)
- Cutout: 22.5 mm
- Construction: modular — lens/head (M22-L-B, 216775) + LED element (M22-LED-…) + fixing adapter (M22-A)
- Approvals: UL, CSA, CE
5. Ordering & Compatibility
Fits 22.5 mm cutouts, M22 system. Confirm the LED voltage and that you have the lens + LED element + fixing adapter (some catalog numbers bundle these; the M22-L-B lens is 216775). Other colors/voltages are separate M22-L codes (e.g. M22-L-Y yellow, #463).
6. Known Issues
No notable reliability issues. Practical care: match the LED voltage, confirm the modular pieces are all present, and remember it's an indicator light (status only), not a pushbutton.

安装快速参考
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.

故障排除
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.
