ABB MLBL Series LED Block, 230V Voltage, Yellow Illumination - 1SFA611621R1073 MLBL-07Y

This LED Block provides a Compact illuminated indication solution for control and automation panels, delivering a clear yellow signal from an integrated LED at line voltage. Designed for straightforward panel mounting, it combines a screw Terminal connection with a small footprint for installation in tight assemblies while operating across typical industrial ambient conditions.

Features and Benefits:

• 230V AC rating enables direct mains signalling for control circuits
• LED illumination gives long-life Visual indication and low power draw
• Screw Terminal provides secure electrical connection for panels
• 10mm width allows dense arrangement in Terminal strips
• Operates from -25°C to +70°C for wide ambient range

Applications

• Suitable for control panel status indication in automation racks
• Ideal for machine-room warning lights and operator interfaces
• Used for signal indication on distribution and switchgear fronts
• Can be used for retrofit replacements in industrial indicator arrays

What mounting or connection method is required for installation?

It connects via screw terminals, allowing direct wiring to standard panel cabling without additional adaptors.

How does it behave under varying ambient temperatures?

The unit remains operational between -25°C and +70°C, maintaining illumination performance across that span.

What Visual output should be expected from the indicator?

It emits a yellow light from an integrated LED intended for clear status signalling in lit panels.

Are there size constraints to consider for dense assemblies?

The Block has a narrow 10mm width, enabling close lateral spacing when multiple indicators are installed.
