ABB MLBL Series LED Block, 24V Voltage, Yellow Illumination - 1SFA611621R2013 MLBL-01BY

This LED Block provides a Compact Visual indication solution for control and automation equipment, supplying a yellow light for status signalling in electrical assemblies. It operates from a low-voltage supply suitable for AC or DC systems and is intended for panel-mount or module-mounted environments within industrial installations.

Features and Benefits:

• Designed for 24V AC/DC operation enabling flexible supply options
• Screw Terminal connection for secure electrical fastening
• LED illumination reduces power consumption compared with lamps
• Rated to operate from -25 to 70°C for wide ambient conditions
• Complies with multiple safety and materials standards for system integration

Applications

• Suitable for signalling on control panels in automation cabinets
• Ideal for use in machine control stations to indicate status
• Used with Terminal blocks and modular assemblies in switchgear
• Can be used for field wiring panels requiring visible indicators

What type of Terminal does it use and why is that important?

It uses a screw Terminal which provides a robust mechanical and electrical connection for wiring in industrial environments and simplifies installation and maintenance.

Which regulatory approvals are relevant for integration into equipment?

It holds recognised approvals covering electrical safety and material restrictions, enabling use in projects that require conformity to established industrial standards.

How does the LED illumination colour affect visibility in panels?

The yellow illumination offers distinct contrast compared with other indicator colours, aiding quick Visual identification of specific statuses in clustered indicator arrays.

What is the intended mounting or placement for this indicator?

It is intended for Compact panel or module mounting where a small-format light Block is required for function indication.
