ActivoSIRIUS ACT Green LED Indicator Light 24V
Green LED indicator light, Siemens SIRIUS ACT series. 22mm cutout, 24V AC/DC, IP66/IP67/IP69K.
Aplicaciones comunes
Green LED indicator from the SIRIUS ACT range. Shows running/active status on Siemens automation panels. The integrated LED accepts 24V DC — connects directly to Siemens S7 PLC digital outputs or ET 200SP distributed I/O. Found on motor control centers in automotive plants, pharmaceutical clean rooms, and food/beverage production lines using Siemens automation. The smooth green lens provides uniform illumination visible from several meters away.

Referencia rápida de instalación
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.

Solución de problemas
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.
