ABB ML1-100R — Modular Red LED Indicator Light 24V

Red LED pilot light, ABB Modular series. 22mm cutout, 24V AC/DC, IP65.

Common Applications

Red LED indicator light from ABB's modular pilot device range. Red indicates fault, alarm, or stopped condition per IEC 60204-1. Commonly installed on motor control centers to show drive fault status, on process panels to indicate high-temperature or high-pressure alarms, and on power distribution boards to show breaker tripped conditions. Pairs with the green ML1-100G to form a running/fault status pair — green lit means running normally, red lit means fault or stopped. The ML1 series shares the same 22mm mounting as ABB MP-series push buttons for a consistent panel layout.

Specifications

Certifications Third-party safety certifications. UL = required for US NEC installations. CE = EU compliance. CSA = Canadian standards.	UL, CSA, CE
Color Button/actuator color. Green = start/go, Red = stop/emergency, Yellow = caution, Blue = reset (per IEC 60204-1).	Red
Cutout Diameter The hole size you drill in your panel to mount this button. 22mm is the most common industrial standard worldwide.	22mm
IP Rating IP65: Dust-tight and protected against low-pressure water jets. Suitable for indoor industrial and light washdown.	IP65
LED Color Color of the built-in LED indicator light.	Red
LED Voltage The voltage required for the built-in LED. Must match your control circuit voltage (typically 24V DC or 230V AC).	24V AC/DC
Material The bezel/body material. Metal bezels are more durable in harsh environments. Plastic is lighter and cheaper.	Plastic
Mounting Type How the button attaches to the panel. Panel mount is standard — installs through a cutout from the front.	Panel

Installation Quick Reference

Panel cutout: 22mm. 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.
