Solid state relays (SSRs) are an important component of any industrial control system. As a type of switching device, they are part of the essential automation equipment used to control or switch the flow of current, either mechanically or electrically. One of the most reliable, efficient, and cost-effective SSRs on the market today is the LBB126. This piece of equipment is especially useful for requirements such as load control, start-up timing, and overcurrent protection.

General

The LBB126 is a miniaturized and fully encapsulated SSR, designed for use in a wide range of industrial settings. It operates at a wide voltage range of 24-480 VAC and offers excellent electrical insulation. With an on-state resistance of up to 1.2 ohms, the LBB126 has excellent surge performance, making it a great choice for applications such as switching and motor-starting in a temperature range of -20 to 80°C.

Design

The LBB126 is a true solid state device, meaning it does not contain any moving parts. By eliminating components which are prone to wear and tear, the LBB126 is designed for long life and reliable operation. Its design allows for an easy installation, utilizing a variety of mounting options like DIN-rail, panel, screw, and socket types. The LBB126 also features thermal cut-out protection, which helps prevent the exposure of unit and circuit-specific components to dangerous operating temperatures.

Application Field

The LBB126’s versatility makes it ideal for a wide range of applications. Its ability to control multiple types of loads such as incandescent lamps, motors, transformers, solenoids, and relays can be used across everything from small-scale HVAC to large-scale industrial control. Its exceptional insulation ensures safety and serves to minimize the system’s susceptibility to failure.

Working Principle

The LBB126 utilizes a power MOSFET as its output transistor. When voltage is applied to the MOSFET, electrical current flow is established and the relay is turned “on”, while removal of the voltage causes the relay to turn “off”. In contrast to traditional mechanical relays, SSRs have no moving parts, dramatically improving their reliability and providing faster, quieter switching. In addition, the elimination of contact elements reduces arcing and sparks, resulting in a safer operation.

Conclusion

The LBB126 is an extremely versatile and reliable solid state relay, designed for a wide range of industrial applications. By utilizing its unique structure and design, the LBB126 significantly increases the safety of industrial systems while providing exceptional protection from overloads and short circuits. With its comprehensive features and high performance, the LBB126 ensures reliable operation and cost-effectiveness for any type of control system.
