Specifications

The ES2HB SSR has a rated load voltage of up to 240 VAC and a load current of up to 2 Amps. It features zero-cross switching, which minimizes inrush current and reduces electrical noise. The isolation voltage is typically 2500 VAC. The input voltage is typically 4-32VDC. The operating temperature range is typically -30°C to +80°C.

The ES2HB solid state relay is often used in applications where frequent switching is required, as it does not suffer from the mechanical wear and tear associated with electromechanical relays. Its small size and silent operation make it suitable for use in a wide range of industrial and commercial equipment. The optical isolation provides a high degree of safety, protecting control circuits from voltage spikes and surges from the load side.
