1SFA611621R2023 ABB MLBL-02BY 48 V AC/DC Yellow LED Lamp Block

Why Choose the ABB MLBL-02BY Lamp Block?

The ABB MLBL-02BY is a modular yellow LED lamp block designed for rear-mounted industrial indication applications. Part of ABB's 22 mm pilot-device offering, it is specifically intended for use in compatible MEP plastic enclosures or on DIN rail, providing a compact integrated light source for control and signalling installations.

Rated for 48 V AC/DC operation, the MLBL-02BY incorporates a yellow LED with a rated current of 10 mA and a nominal wavelength of 588 nm. The integrated solid-state light source removes the need to select and install a separate replaceable lamp while providing a clearly identifiable yellow indication.

With a compact modular construction and a unit weight of approximately 0.012 kg, the MLBL-02BY is well suited to machine-building and panel-building applications requiring rear-mounted visual indication. Its yellow illumination can be assigned to machine-defined warning, attention or other status functions according to the signalling scheme of the installation.

Reliable Yellow LED Indication for Industrial Controls

Yellow visual indication is commonly incorporated into industrial control systems where an easily distinguishable signal is required. The ABB MLBL-02BY provides an integrated 588 nm yellow LED for rear-mounted applications, allowing the specific meaning of the indication to be defined according to the machine or process control scheme.

The 48 V AC/DC design makes the MLBL-02BY suitable for both AC and DC indication circuits at its specified voltage. When a DC supply is used, correct polarity must be observed using the marked X1 (+) and X2 (-) connections, helping ensure correct installation of the integrated LED block.

Typical Applications

• Industrial yellow status-indication circuits.
• Machine-defined warning and attention indication.
• Compatible ABB MEP plastic enclosure assemblies.
• DIN-rail indication installations.
• Machine-control panels.
• Industrial operator and control stations.
• Production and packaging machinery.
• Conveyor and material handling systems.
• OEM machinery and industrial automation systems.
