The Lovato HS1A2NN025D024 is a compact single-phase solid state relay (SSR) designed for reliable electronic switching of AC electrical loads. As part of the Lovato HS series, this miniature relay uses semiconductor switching technology rather than mechanical contacts, providing silent operation, rapid switching and long service life for industrial control applications.
The HS1A2NN025D024 uses an SCR semiconductor output with zero-crossing switching, helping minimise electrical disturbances when switching compatible AC loads. It accepts a 4–30 V DC control signal and switches loads across a rated operating voltage range of 12–280 V AC, making it straightforward to interface with PLC outputs and other low-voltage electronic control systems.
Rated at up to 25 A AC-51 at 40 °C for resistive loads and 7 A AC-53 at 40 °C for motor loads, the HS1A2NN025D024 provides substantial switching capability from a miniature package. Faston terminals, screw mounting and an operating temperature range from -40 to +90 °C make it well suited to industrial panels, heating equipment and automated machinery.
Solid state relays switch electrical loads electronically without the moving contacts found in conventional electromechanical relays and contactors. This enables silent operation and rapid switching while eliminating mechanical contact wear, making SSR technology particularly valuable in applications requiring frequent switching or long operating life.
The Lovato HS1A2NN025D024 combines these benefits with zero-crossing switching, a wide 12–280 V AC load range and a low-voltage DC control input. Its 25 A AC-51 rating makes it particularly suitable for resistive loads such as electrical heating elements, while its AC-53 rating also permits use with appropriately sized motor loads when all installation and thermal requirements are observed.
