Why Choose the ABB MLBL-05Y Lamp Block?
The ABB MLBL-05Y is a modular yellow integrated LED lamp block designed for illuminated operators within ABB's 22 mm modular pilot device range. Supplied under ABB order code 1SFA611621R1053, it provides a compact internal light source for compatible illuminated pushbuttons, selector switches and other industrial control devices.
The MLBL-05Y operates from a 110–130 V DC supply and incorporates a yellow LED with a rated current of 9.9 mA. The LED has a wavelength of 588 nm and luminance of 300 mcd, providing a clearly identifiable yellow indication through a compatible ABB illuminated operator.
Designed for front mounting, the MLBL-05Y integrates into ABB's modular pilot device system and provides IP20 terminal protection. Its compact 44 × 10 × 35 mm construction and low net weight make it well suited to machinery, automation equipment and industrial control-panel assemblies where dependable visual indication is required.

Yellow LED Indication for ABB Modular Pilot Devices
LED lamp blocks provide the internal illumination behind compatible pilot device operators, allowing machine states and process conditions to be communicated visually. Yellow illumination can be used for caution, abnormal-condition or attention-related signalling according to the indication scheme and applicable standards adopted for the particular machine or installation.
The ABB MLBL-05Y combines a 110–130 V DC integrated yellow LED with ABB's modular front-mounting architecture. It can be combined with compatible illuminated pushbuttons, selector switches and other ABB modular operators, providing a compact illumination solution for industrial machinery and automation panels.
Typical Applications
- Illuminated industrial pushbuttons.
- Machine caution and status indication.
- Automation and process control panels.
- Production and manufacturing equipment.
- Operator stations and control consoles.
