Why Choose the ABB MLBL-05BL Lamp Block?
The ABB MLBL-05BL is a modular blue LED lamp block designed for reliable illuminated indication in industrial pilot-device and control applications. Identified by ABB order code 1SFA611621R2054, it combines an integrated blue LED with a rear-mounting format for use in compatible ABB control and signalling assemblies.
As part of ABB's modular plastic pilot-device range, the MLBL-05BL is designed for use in MEP plastic enclosures or on DIN rail. Its integrated LED construction provides efficient, durable illumination for machinery, control panels, operator stations and industrial automation equipment.
The MLBL-05BL operates from a 110–130 V DC supply with a rated current of 9.8 mA. Its blue LED has a wavelength of 468 nm and a luminance of approximately 450 mcd, providing a clearly identifiable visual signal for industrial status indication.

Reliable LED Indication for Industrial Controls
LED lamp blocks provide illumination for visual signalling in industrial operator interfaces and control equipment. The blue illumination of the ABB MLBL-05BL enables clear identification of machine, process or control-system conditions where a blue visual signal is required.
The integrated LED construction provides an efficient and durable illumination solution without requiring a separate replaceable lamp. For DC operation, correct polarity should be observed using the marked X1 (+) and X2 (−) connections.
Typical Applications
- Industrial control panels and electrical enclosures.
- Machine status and operating-condition indication.
- Operator stations and signalling equipment.
- Factory automation and production machinery.
- MEP plastic enclosure assemblies.
- DIN-rail-mounted industrial indication systems.
