Product Description

Siemens 8WN4420-5AF00 Continuous Light Element – Blue, 24V AC/DC, 70mm

The Siemens 8WN4420-5AF00 is a continuous-light LED element for the Siemens 8WN44 signalling-column system. The exact article is designed for blue light, operates at 24 V AC/DC, and uses the 70 mm diameter modular signalling-column format. Siemens documentation lists 8WN4420-5AF00 as the blue continuous-light LED element in the 24 V AC/DC range.

For SB Smart, this product is positioned as a Siemens industrial signalling component for machine status indication, control-panel signalling, equipment indication, maintenance and procurement requirements.

Siemens 8WN4420-5AF00 Continuous Light Element

The 8WN4420-5AF00 belongs to the Siemens 8WN44 signalling columns, 70 mm diameter, modular family. The 8WN44 system uses modular LED light and buzzer elements that can be combined to create a multi-level signalling column. Siemens documentation states that up to five elements can be mounted in one modular column.

The exact article is the blue continuous-light LED element for 24 V AC/DC.

Blue LED Indication

The product provides a continuous blue visual indication.

Blue signalling can be assigned to conditions such as:

• Equipment status indication

• System or machine operating condition

• Special status indication

• Process condition indication

• Operator information

• Panel signalling

The actual meaning of the blue signal should be defined by the machine, equipment or electrical-panel control philosophy.

Continuous Light Function

The 8WN4420-5AF00 produces a steady continuous light when energized, unlike the 8WN44 blinking-light variants.

For the 24 V AC/DC family, Siemens lists:

• 8WN4420-5AB00 – Red

• 8WN4420-5AC00 – Green

• 8WN4420-5AD00 – Yellow

• 8WN4420-5AE00 – Clear

• 8WN4420-5AF00 – Blue

This makes the 5AF00 the blue continuous-light version.

24 V AC/DC Operation

The exact 8WN4420-5AF00 is designed for 24 V AC/DC operation. Siemens product data lists the complete 24 V AC/DC continuous-light range with individual colour-specific article numbers.

The control voltage should be checked before installation to ensure compatibility with the signalling circuit.

70 mm Diameter Modular System

The 8WN44 signalling-column platform uses a 70 mm diameter modular format. The 8WN4420-5AF00 is designed to be installed within this system.

This allows the blue light element to be combined with other compatible 8WN44 signalling elements.

LED Light Element

The product is an LED light element. Siemens groups the 8WN44 products under light elements with LED lamp, with separate continuous and blinking versions.

LED signalling provides a clear visual indication and is suitable for modular industrial signalling applications.

IP65 Signalling-Column System

The Siemens 8WN44 signalling-column system is specified with IP65 protection and uses a thermoplastic enclosure with a 70 mm diameter.

This makes the system suitable for many industrial environments where protection against dust and water jets is required, provided the complete assembly is correctly installed.

Modular Signalling Column

The 8WN4420-5AF00 is a modular signalling element rather than a complete signalling column.

It can be assembled with compatible:

• LED light elements

• Blinking light elements

• Buzzer elements

• Connection elements

• Mounting accessories

• Covers

Siemens specifies that up to five elements can be combined in the modular 8WN44 system.

Continuous vs Blinking Blue Light

For blue 24 V AC/DC signalling:

8WN4420-5AF00 provides continuous blue light.

8WN4420-5BF00 provides blinking blue light.

The continuous version is appropriate where a steady status indication is required, while the blinking version is more suitable for attention or warning conditions.

Industrial Status and Indication Applications

The 8WN4420-5AF00 can be considered for compatible applications such as:

• Industrial control panels

• Machine-status indication

• Electrical switchboards

• Equipment signalling

• Process-status indication

• Industrial machinery

• Panel warning and indication systems

• Maintenance and replacement applications

The exact signal meaning should be defined by the equipment designer.

Compatible 8WN44 Signalling Accessories

Siemens lists compatible 8WN44 accessories including:

• 8WN4408-0AF00 – Connection element

• 8WN4408-0AG00 – Cover

• 8WN4408-0DH00 – Foot with 60 mm pipe

• 8WN4408-0DJ00 – Foot with 80 mm pipe

• 8WN4408-0DA00 – Foot with 110 mm pipe

• 8WN4408-0CC00 – Wall-mounting bracket

• 8WN4408-0CF00 – Mounting with feet and pipe

• 8WN4408-0CG00 – Pivoting base / mounting without feet and pipe

The exact accessory selection depends on the intended signalling-column mounting arrangement.

Replacement and Maintenance

The 8WN4420-5AF00 can be useful when an existing 8WN44 signalling column requires replacement of its blue continuous-light LED element.

Before ordering, verify:

• 8WN44 system compatibility

• Blue light requirement

• Continuous or blinking function

• 24 V AC/DC supply

• 70 mm system diameter

• Existing connection and mounting arrangement

This prevents accidental substitution of a different colour or blinking version.

Standard Package Quantity

Siemens documentation specifies a standard package quantity of 1 unit for the 8WN44 continuous-light elements.

This is suitable for individual replacement, panel assembly and maintenance procurement.

Product Dimensions

A current Indian product listing for 8WN4420-5AF00 reports approximate dimensions of 80 mm × 85 mm × 80 mm and a listed weight of approximately 0.5 kg. These marketplace dimensions should be treated as reference values and verified against the official mechanical drawing where exact panel clearance is critical.
