The Lovato HS2B2NN025D024 is a compact and reliable two-phase solid state relay (SSR) designed for contactless switching of AC resistive loads in industrial control, heating and automation applications. As part of the Lovato HS2B solid state relay series, it uses semiconductor switching technology to provide fast, silent operation without the mechanical contact wear associated with conventional electromechanical relays.
This hockey-puck style relay features an SCR semiconductor output with zero-crossing switching, helping reduce switching disturbances when controlling compatible AC loads. Its two-pole configuration allows two phases to be switched electronically, while the 3–32 V DC control input makes it suitable for connection to PLC outputs, temperature controllers and other electronic control equipment.
With a rated operating current of 25 A AC-51 at 40 °C and a 12–280 V AC rated operating voltage, the HS2B2NN025D024 is designed primarily for resistive-load applications. Faston terminals provide convenient electrical connections, while the relay can be combined with a suitably rated heatsink to provide the thermal dissipation required for operation at higher load currents.
Solid state relays such as the Lovato HS2B2NN025D024 control electrical loads using semiconductor devices rather than mechanical contacts. This provides silent, rapid switching without contact bounce or mechanical wear, making solid state relays particularly suitable for applications involving frequent switching cycles.
The HS2B2NN025D024 uses SCR outputs and zero-crossing operation to switch compatible AC resistive loads close to the supply voltage zero point. When installed with an appropriately selected heatsink, the relay provides a robust switching solution for industrial heating, temperature regulation and automated process-control systems.
