Why Choose the Lovato HS1B5NV060E230 Solid State Relay?
The Lovato HS1B5NV060E230 is a single-phase 60 A solid state relay from the HS1B series, designed for reliable electronic switching of resistive and inductive AC loads. Its hockey-puck construction, SCR semiconductor output and screw terminals make it suitable for industrial heating, machinery and automation applications requiring frequent and silent switching.
The HS1B5NV060E230 switches loads across a wide 24–510 V AC operating range and accepts a versatile 20–265 V AC/DC control input. This broad AC/DC control range makes the relay particularly useful where a higher-voltage control signal is available instead of the low-voltage DC input used by other HS1B variants.
With zero-cross switching, the relay switches close to the zero-voltage point of the AC waveform to help reduce switching disturbances. It is rated at 60 A AC-51 at 40 °C for resistive loads and 12 A AC-53 at 40 °C for motor loads, while integrated VDR protection and 4000 V input-to-output isolation support dependable industrial operation.

Wide-Range AC/DC Control with Zero-Cross Switching
Unlike an electromechanical relay, the HS1B5NV060E230 switches its load electronically using an SCR semiconductor output, eliminating moving switching contacts. This enables silent operation and avoids mechanical contact wear, making the relay well suited to applications with frequent switching cycles such as industrial heaters, ovens and automated process equipment.
The 20–265 V AC/DC control range provides substantial flexibility when integrating the relay into different control circuits. Zero-cross operation switches the AC load near the zero-voltage point of the waveform, while suitable heatsinking is required according to load and ambient conditions; for operation at the specified rated AC-51 current, Lovato specifies a heatsink thermal resistance of ≤0.55 K/W.
Typical Applications
- Industrial electric heating elements.
- Industrial ovens and heating machinery.
- Temperature-control systems.
- Resistive load switching.
- Suitable small motor and inductive-load switching.
- Packaging and processing machinery.
- Industrial automation panels requiring frequent solid-state switching.
