What type of signalling component is this?
It is a SIRIUS continuous light element with an integrated blue LED, intended for use in modular signal columns and visual indication assemblies.
What colour does the light element produce?
The light element produces a blue optical signal, making it suitable for applications where blue status indication is required.
What voltage does it operate on?
It operates at 24 V AC/DC, including 24 V AC at 50 Hz, 24 V AC at 60 Hz, and 24 V DC.
Is the optical signal flashing or continuous?
The optical signal is continuous. It is designed to provide a steady blue light rather than a flashing or rotating indication.
What is the diameter of the signal column element?
The signal column element has an outer diameter of 50 mm.
What are the main dimensions of the component?
The component is approximately 67 mm high and 52 mm wide, with a 50 mm signal column element diameter.
What type of light source is used?
It uses an integrated LED light source. For 8WD4220-5AF, the LED has a stated service life of 100,000 hours.
What is the maximum current consumption?
The maximum current consumption is 30 mA, which makes it a low-current visual signalling component.
What mounting method is used?
It uses a bayonet fastening method, allowing it to be fitted into compatible modular signal column assemblies.
What material is the enclosure made from?
The enclosure material is PC, which refers to polycarbonate.
What ingress protection rating does it have?
The component is rated IP54, meaning it has limited protection against dust ingress and splashing water when correctly installed in a suitable assembly.
What operating temperature range is specified?
The specified operating temperature range is -20 °C to +50 °C.
What is the stated light intensity?
The stated light intensity is 0.12 cd, with a specified range of 0.08 cd to 0.18 cd.
What voltage tolerance is specified?
The operating voltage tolerance is +10% and -10%, allowing operation within the defined variation around the 24 V rated supply.
Where is this component typically used?
It is typically used in industrial signal towers, machine status indicators, control panels, and automation systems where a clear blue continuous visual indication is needed.
- Visual status indication on industrial machinery and production equipment
- Blue steady-light signalling within 50 mm signal tower assemblies
- Machine condition indication for operator panels and control stations
- Process step or mode indication in automated manufacturing lines
- Local visual alerts for conveyors, packaging machines and assembly systems
- Panel-mounted signalling where a 24 V AC/DC LED light element is required
- Replacement or spare light element for compatible Siemens SIRIUS signal columns
- Indication of auxiliary functions, manual modes or operator acknowledgement states
- Visual identification of equipment status in factory automation environments
- Use in control cabinets and machine enclosures requiring compact bayonet-mounted signalling
