Suitable for
Industrial automation signaling systems
Status indication in control panels
Visual monitoring of machine states
Integration into 50 mm and 70 mm diameter signaling columns
When it may not be suitable
This bulb is not intended for use in high-vibration environments where LED alternatives might offer superior longevity and resistance to mechanical stress. Additionally, it is not compatible with signaling columns that require a different base type or voltage rating outside of the specified 24V AC/DC range.
Key specifications
Power rating: 5W
Base type: BA15d
Operating voltage: 24V AC/DC
Compatibility: Siemens 8WD42 and 8WD44 signaling columns
Design: Incandescent technology
How to use
To install the bulb, ensure that the power supply to the signaling column is completely disconnected to prevent electrical hazards. Access the specific module of the signaling column by removing the lens cover according to the manufacturer's instructions for the 8WD series. Carefully remove the old bulb by pressing down and rotating it counter-clockwise, then insert the new 8WD4328-1XX bulb into the BA15d socket, pressing down and rotating clockwise to lock it into place. Replace the lens cover and restore power to verify that the light functions correctly.
What to consider before purchase
Verify the voltage requirements of your existing signaling column system.
Ensure the BA15d base matches your current module socket.
Check the compatibility with your specific 8WD42 or 8WD44 series column diameter.
Usage recommendations
Always replace bulbs while the system is powered off and allow the unit to cool down if it has been in operation, as incandescent bulbs can reach high temperatures during use.
