Why Choose the Lovato HS2B6NN050D024 Solid State Relay?
The Lovato HS2B6NN050D024 is a robust two-phase solid state relay (SSR) designed for contactless switching of AC resistive loads in industrial heating, process control and automation applications. As part of the Lovato HS2B solid state relay series, its hockey-puck format combines compact construction with SCR semiconductor technology for reliable high-cycle switching.
This relay provides zero-crossing switching, helping reduce electrical disturbance when compatible AC loads are switched. With no mechanical power contacts to wear, the HS2B6NN050D024 provides fast and silent operation, making it particularly suitable for applications where heaters and other resistive loads are switched frequently by PLCs, temperature controllers and automation systems.
With a rated operating current of 50 A AC-51 at 40 °C, a 24–600 V AC rated operating voltage and a 10–30 V DC control input, the HS2B6NN050D024 provides substantial switching capability in a compact package. Its screw terminals simplify wiring, while an appropriately rated heatsink is required to provide suitable thermal dissipation when operating at rated load.
