ABB MLBL Series LED Block, 48V Voltage, White Illumination - 1SFA611621R1025 MLBL-02W

This LED Block provides a Compact illuminated indication solution for control panels and equipment operating at low voltage. It is designed to deliver a clear white signal in automation and electrical systems, integrating directly into screw‑terminal assemblies and functioning across AC and DC supply environments. The unit is suitable where small form‑factor Visual status indication is required.

Features and Benefits:

• Operates from 48V AC/DC for versatile supply compatibility
• Consumes 9.7mA enabling low current draw for panel circuits
• White LED illumination for high-contrast signalling
• Screw terminals for secure, tool‑based connections
• RoHS‑compliant construction to meet material restrictions

Applications

• Suitable for industrial panel indication in control cabinets
• Ideal for status signalling on machinery and switchgear
• Used with PLC interfaces for Visual output monitoring
• Can be used for fault and ready indicators in automation racks

What temperature range can it tolerate during operation?

It functions reliably between -25°C and +70°C, allowing use in a wide range of indoor industrial environments.

How Compact is the unit for tight panel cutouts?

The module has a very small footprint with a length of 0.042 m, width of 0.01 m and height of 0.044 m, permitting installation in confined spaces.

Which termination method is provided for wiring?

Terminals are screw type, permitting conventional stripped‑wire connections and straightforward maintenance.

Does the indicator include the light source or require external LEDs?

The device includes an integrated LED illumination element, delivering the specified white signal without additional components.
