ABB MLBL Series LED Block, 24V Voltage, Green Illumination - 1SFA611621R2012 MLBL-01BG

This LED Block is a Compact illumination module intended for control panels and industrial equipment, providing clear Visual signalling in electrical and automation environments. It operates from a 24V AC/DC supply and is designed with a screw‑terminal Interface for straightforward integration into existing assemblies. The unit features a green LED indicator and is suitable for use across a broad ambient temperature range.

Features and Benefits:

• Green LED illumination for Rapid status identification
• Screw terminals allow secure electrical connection under vibration
• RoHS‑compliant construction minimises hazardous substances
• Wide ambient temperature rating supports harsh‑site operation
• LED included providing immediate readiness at installation

Applications

• Suitable for control panels requiring 24V Visual status indicators
• Ideal for PLC and switchgear Visual signalling tasks
• Used with industrial automation racks for component status feedback
• Can be used for indicator retrofits in electrical distribution enclosures

What mounting or connection method does it use for panel integration?

Electrical connections are MADE via screw terminals, enabling firm wire clamping and simple replacement without specialised connectors.

How does the unit cope with temperature extremes in plant environments?

It functions across an operating range from -25°C to +70°C, allowing deployment in cold storage areas and warm plant rooms.

Is the illumination component supplied with the unit or must it be ordered separately?

The module includes the LED element, so it is operational upon installation without additional parts.

What physical form factor should installers expect for tight spaces?

The Block presents a very small footprint, with dimensions approximately 0.042 m in length and 0.044 m in height and a 10mm width for dense panel layouts.
