ABB 1SFA611621R1072 is an MLBL-07G LED block designed for use with ABB modular plastic pushbutton assemblies. This green LED block provides clear visual indication within control and signalling panels, helping operators identify machine or process status at a glance. Its updated PCB design is suitable for standard control circuits as well as applications where inductive loads may create higher peak voltages. Rated up to 15 mA, the MLBL-07G is engineered to withstand inductive voltage spikes up to 55 V AC without unwanted glimmering, supporting reliable indication in industrial environments. Compact and purpose-built for ABB pilot device configurations, it is a practical replacement for older MLBL-99G variants.

What type of component is this?
This is an MLBL-07G LED block used within modular pushbutton and pilot device assemblies. It provides green LED indication as part of a compatible operator or signalling arrangement.
What does the “G” in MLBL-07G indicate?
The “G” identifies the LED colour as green. This makes the unit suitable for applications where a green visual indication is required, such as run, ready, enabled or normal-condition signalling.
What is this LED block commonly used for?
It is typically used in industrial control panels, machinery interfaces and operator stations where a clear illuminated indication is needed alongside pushbuttons, selector switches or other pilot devices.
Is this suitable for use with modular pushbutton assemblies?
Yes. The MLBL-07G is designed for use as part of a modular plastic pushbutton LED range, allowing it to be integrated into compatible pilot device configurations.
What improvement was made to this LED block range?
The printed circuit board design for the MLBL LED block range was enhanced for improved performance in circuits affected by high peak voltage inductive effects. Products made after 20 October 2022 use the updated PCB design.
What rated current is associated with the enhanced design?
The enhanced MLBL LED block design has an increased rated current of up to 15 mA, supporting reliable indication in suitable standard applications.
Can this LED block handle inductive voltage spikes?
The enhanced design is intended to withstand inductive voltage spikes of up to 55 V AC without glimmering, making it suitable for circuits where inductive effects may otherwise affect LED behaviour.
Which older green LED block does this replace?
The MLBL-07G, including 1SFA611621R1072, is listed as the replacement for the older MLBL-99G version. This allows the standard MLBL-07G type to be used instead of the earlier special version.
What should be checked before fitting this LED block?
Before fitting, check that the control voltage, operator assembly and panel device configuration are compatible with the MLBL-07G. The electrical circuit should also be assessed to ensure the LED block is being used within its intended ratings.
What kind of visual indication does this component provide?
It provides a green illuminated signal. In industrial panels, green indication is often used to show an active, healthy, ready or permitted operating state, depending on the machine or panel design.
- Illuminating pushbuttons and pilot devices in industrial control panels
- Providing clear green visual status indication on machinery operator interfaces
- Indicating run, ready, available or active conditions in automation systems
- Supporting panel-mounted controls in motor starting and control applications
- Use in machine control stations where compact LED indication is required
- Retrofitting compatible ABB modular plastic pushbutton assemblies
- Replacing obsolete MLBL-99G LED block applications with the MLBL-07G type
- Enhancing visibility of control functions in production and process environments
- Indicating circuit or equipment status in electrical cabinets and control desks
- Supporting operator feedback in manufacturing, packaging and material handling equipment
