LCA701STR

Solid state relays are electrical relays with a semiconductor switching elements and are used to switch circuits in electronic systems that may or may not involve other relays. The LCA701STR is one such relay, designed for efficient operation and superior performance. In this article, we will discuss its application field and working principle.

Application Field

The LCA701STR is designed to be used for general purpose industrial switching applications. It supports DC and AC voltage of up to 250 V and offers a wide range of features including a manual switch action with a wide operating temperature range (from -40°C to +85°C). It is also compatible with a variety of industrial automation equipment, including programmable logic controllers (PLCs), motor controllers, and pressure monitoring systems.

Furthermore, the LCA701STR features proven PTC stainless steel contacts that have been tested to 500,000 cycles, making it an ideal choice for reliable heavy-duty switching in a variety of applications, including machinery or appliance control systems. In addition, its tight contact capture ensures reliable switching operations and a longer life expectancy. Finally, its relay terminals are designed with flexible configurations to facilitate easy installation.

Working Principle

The LCA701STR operates using a form of electromagnetic power called static induction. When current flows through the input connection, it generates a static magnetic field. This field is then converted to an electrical signal that is sent to the output terminals. The output terminals then activate the electromagnetically actuated switch which in turn switches the circuit on or off. When the circuit is switched off, the static induction force is released and the LCA701STR returns to its inactive state.

When the input current is reversed, the electromagnetic field is also reversed and the LCA701STR reverses its output connection. This allows for two-way and three-way switching. In addition, it also allows for the use of external components such as timers and sensors for intelligent control of the relay.

Conclusion

In conclusion, the LCA701STR is a reliable and efficient solid state relay that provides excellent performance for industrial switching applications. It features proven PTC stainless steel points and a wide operating temperature range. It also allows for two-way and three-way switching with external components such as timers and sensors for automated control.
