Sort out your switching needs with this solid-state relay from Sensata | Crydom. This component has a broad load voltage range of 24 to 280V, making it a versatile piece of kit. It mounts onto a PCB, so you can build it into your system without a hitch using its pin terminals. Zero-cross switching means it switches on when the voltage is near zero, helping to minimise noise for more efficient performance. A triac output makes this unit suitable for switching medium-power AC loads, so it's just the thing for domestic lighting networks or motor control installations.

• Performs reliably in a temperature range of -30°C to +80°C for use in harsh industrial environments
• Compact dimensions of 43.2 (L) x 10.2 (W) x 25.4mm (H) to add minimal bulk to your system
• Optical isolation of 4kV for protection against shorts, transients and ground loops

Optical isolation converts an electrical signal into a light signal using an LED. A photosensor then receives that light signal and converts it back to an electrical one, blocking any harmful currents trying to flow across the device.
