ABB MLBL Series LED Block, 24V Voltage, Red Illumination - 1SFA611621R2011 MLBL-01BR

This LED Block provides a Compact Visual signalling solution for control panels and equipment, delivering red illumination from a low-current LED at a 24V AC/DC supply. It is designed for use in industrial automation and electrical installations where a small, screw-terminal mounted indicator is required. The component operates across a wide ambient range and is manufactured to comply with RoHS requirements.

Features and Benefits:

• LED draws 9.9 mA for low-energy indicator operation
• Compatible with 24V AC/DC supply for versatile system use
• Screw terminals allow straightforward wiring and secure connections
• Red illumination gives clear status indication in panels
• Operates down to -25 °C enabling cold-environment performance
• Rated to +70 °C for use in warm industrial enclosures

Applications

• Suitable for control panel status indication in automation systems
• Ideal for signal feedback on electrical switchgear and cabinets
• Used with industrial machinery for process state visualisation
• Can be used for retrofit indicator upgrades in legacy panels
• Suitable for distribution boards requiring low-power indication

What mounting type does it use for panel installation?

It is a block-style indicator designed for panel or terminal-block integration using its screw-type terminals for mechanical and electrical fixation.

How does the device perform in cold starts?

The LED remains operational at temperatures as low as -25 °C, preserving indication capability during low-temperature start-up conditions.

What is the electrical current draw during continuous illumination?

The LED consumes approximately 9.9 mA when continuously energised at the specified voltage.

Are there material restrictions related to environmental directives?

It is manufactured in compliance with RoHS standards, addressing restrictions on certain hazardous substances.
