Why Choose the ABB MLBL-01BY Lamp Block?
The ABB MLBL-01BY is a compact and reliable yellow LED lamp block designed for visual indication in industrial control, signalling and automation applications. Supplied under ABB order code 1SFA611621R2013, it forms part of ABB’s modular pilot device range and is intended for rear mounting in compatible pilot device and enclosure assemblies.
The MLBL-01BY features an integrated yellow LED light source, providing clear status indication without requiring a separate replaceable lamp. Its modular construction supports straightforward installation in industrial operator interfaces, while screw-clamp terminals provide secure and convenient electrical connections.
With a rated operating voltage of 24 V AC/DC and a rated current of 9.9 mA, the MLBL-01BY is suitable for common low-voltage industrial control circuits. The yellow LED has a wavelength of 588 nm and luminance of approximately 250 mcd, providing effective visual signalling in machinery and control equipment.

Reliable Illumination for Industrial Pilot Devices
LED lamp blocks provide visual status indication within industrial operator interfaces and signalling equipment. By incorporating the LED directly into the lamp block, the ABB MLBL-01BY provides a compact illumination solution that simplifies pilot device assembly and eliminates the need to fit a separate conventional lamp.
The MLBL-01BY is designed for rear-mounted applications and can be used in compatible ABB pilot device and enclosure configurations. Its 24 V AC/DC operating capability makes it particularly suitable for industrial automation systems where 24-volt control supplies are widely used.
Typical Applications
- Industrial control panels and operator stations.
- Illuminated pushbutton and pilot device assemblies.
- Machine control and automation systems.
- Process control and production equipment.
- Electrical status and warning indication.
- Industrial enclosures and signalling assemblies.
