ABB MLBL Series LED Block, 12V DC Voltage, Red Illumination - 1SFA611621R1001 MLBL-00R

This LED Block is a Compact signal device designed to provide a clear red indication within control panels and equipment operating on low-voltage DC supplies. It is intended for panel-mount or Block-mount use in automation and electrical installations where a Visual LED indication is required. The unit incorporates an integral LED and is compatible with screw-type electrical connections for straightforward installation.

Features and Benefits:

• Operates from 12V DC power supply for low-voltage systems
• Red illumination for high-visibility fault and status signalling
• Screw Terminal connection for secure electrical contact
• LED-based indication for low power consumption
• Rated to function between -25°C and 70°C ambient

Applications

• Suitable for status indication on industrial control panels
• Ideal for signal lamps in automation equipment racks
• Used with Terminal blocks in electrical distribution assemblies
• Can be used for front-panel indication in mechanical systems

What approvals and standards does it meet for industrial deployment?

It carries multiple approvals including CE, UL, cULus and CCC, and conforms to RoHS and REACH requirements for restricted substances.

What type of Terminal is provided and how does it affect installation?

A screw Terminal is fitted, enabling straightforward wiring with common conductors and providing mechanical retention under vibration.

What operating temperature range can be expected in harsh environments?

The device is specified to operate reliably from -25°C up to 70°C, making it suitable for a wide range of ambient conditions.

Is the light source integral and what is its form?

The illumination is an integrated LED offering steady red output as the signalling method.
