Datasheet - 1SFA611621R1055

ABB MLBL Series LED Block, 110 to 130V DC Voltage, 9.8mA Current Rating - 1SFA611621R1055 MLBL-05W

This LED Block provides a compact, panel-ready indication solution for control and automation installations, offering clear white illumination for status signalling at medium DC voltages. It is designed for use where a small, visible indicator with a screw connection is required, and operates across a nominal DC supply suited to industrial systems.

Features and Benefits:

• Operates from a 110-130V DC supply for common control voltages
• Consumes 9.8 mA enabling low-current signalling
• Screw Terminal connection for secure panel wiring
• White LED illumination for high-contrast status indication
• Rated to function between -25 °C and 70 °C for harsh environments
• Conforms to multiple safety standards for regulatory installation

Applications

• Suitable for control panels requiring LED status indicators
• Ideal for automation racks with limited panel space
• Used for signalling on machinery and electrical cabinets
• Can be used in marine or offshore systems with certification needs
• Suitable for retrofit indicator upgrades in switchgear

What Terminal type is used for electrical connections?

It uses a screw Terminal arrangement to provide a reliable clamped connection for panel wiring.

How wide is the unit for panel layout planning?

The indicator Block occupies a 10mm width for tight spacing in mounting schemes.

Is the LED supplied as part of the unit?

Yes, the illumination source is an integrated LED that produces white light.

Which approvals support installation in regulated systems?

It holds multiple approvals including CE, cULus, DNV GL, EAC, RoHS, UL, USA and CCC supporting various regional requirements.

What mounting environments can it withstand thermally?

It will operate across a temperature range from -25 °C up to 70 °C, suitable for many industrial ambient conditions.
