Pepperl+Fuchs M-LB-2.30.T3.D | Surge Protection Barrier | 2-Channel | 30V | DIN Rail

The Pepperl+Fuchs M-LB-2.30.T3.D is a dual-channel surge protection barrier engineered to protect sensitive electronic equipment and signal loops from voltage surges and transients in industrial environments. Designed with a focus on reliability and safety, it is particularly suited for applications in process automation where signal integrity is critical.

Key Features and Product Highlights

• Dual-Channel Protection: Provides independent surge protection for two separate signal loops (e.g., 4-20 mA), optimizing space and cost-efficiency in control panels.

• Rated Voltage: Designed for circuits with a maximum operating voltage of 30V, making it suitable for standard industrial control and instrumentation signals.

• Robust Surge Immunity: Protects against transient overvoltages, such as those induced by lightning or switching events, safeguarding PLCs, DCS modules, and other control system assets.

• DIN Rail Mounting: Compact form factor for easy installation on standard 35mm DIN rails, facilitating simple integration into marshalling cabinets and control panels.

• Maintenance-Free Operation: The passive design ensures long-term reliability without the need for routine maintenance or batteries.

• Visual Status Indication: Typically features a visual indicator (often a green LED or mechanical flag) to show the operational status and confirm the protective element is functional.
