## Long description

The Relpol RSR30-D12-D1-02-040-1 is a high-performance, single-pole solid state relay engineered for reliable switching in electronic control systems. Designed specifically for PCB mounting, this compact component offers a 4A switching capacity and operates efficiently with a 7-20V DC control voltage. By utilizing semiconductor technology, it provides silent operation and rapid switching speeds, making it an ideal choice for modern industrial and automation applications where durability and precision are essential.
Advantages
This solid state relay offers significant benefits over traditional electromechanical relays, primarily due to its lack of moving parts, which results in a much longer service life and immunity to mechanical wear. Its silent operation is particularly advantageous in noise-sensitive environments, while the fast switching response ensures high-speed performance for demanding control tasks. The compact design facilitates space-saving integration onto printed circuit boards, and the robust construction ensures consistent reliability even in challenging industrial conditions.
Suitable for
Industrial automation control systems
Heating and cooling equipment management
Lighting control circuits
Electronic instrumentation and testing devices
Small motor control applications
This relay may not be suitable for applications requiring high-voltage AC switching, as it is specifically designed for DC control and switching tasks. It is also not intended for use in environments where the ambient temperature exceeds the manufacturer's specified thermal limits or where significant surge currents beyond the 4A rating are expected.
Key specifications
Configuration: 1-pole (1P)
Switching capacity: 4A
Control voltage range: 7-20V DC
Mounting type: PCB mount
Technology: Solid state (semiconductor)
To use the Relpol RSR30-D12-D1-02-040-1, solder the relay directly onto the designated area of your printed circuit board, ensuring that the pin orientation matches your circuit layout. Connect the control signal to the input terminals within the 7-20V DC range and connect your load to the output terminals. Verify that the load current does not exceed the 4A limit to prevent overheating or component failure.
What to consider before purchase
Ensure the control voltage of your system falls within the 7-20V DC range.
Verify that your load requirements do not exceed the 4A maximum switching capacity.
Confirm that your PCB layout supports the physical footprint of this relay.
Check if your application requires heat sinking for sustained high-current operation.
Usage recommendations: Always ensure proper ventilation around the relay on the PCB to maintain optimal operating temperatures and extend the lifespan of the component. Avoid exceeding the specified voltage and current ratings to prevent permanent damage to the semiconductor internal structure.
