Product Details

Sensata | Crydom Solid-State Relay, 10ms Turn-On Time, DIN Rail Mounting - CKR Series - CKRA2420

Make or break your circuit with lighting speed using this solid-state relay from Sensata | Crydom. Thanks to its maximum turn-on time of 10ms and turn-off time of 40ms, you can rest assured that it swiftly switches power to your device. As it converts an electrical signal to an optical one, this unit doesn't have any moving parts, reducing the risk of mechanical wear for a longer lifespan. Its thermally conductive epoxy case means it can stand the heat in demanding conditions. Use it in data centres or medical equipment.

• Wide operating temperature range between -40°C and +80°C for use in harsh industrial environments
• Designed for mounting on a DIN rail for tool-free installation
• Box clamp terminals for secure wiring

What's the control voltage range of this relay?

This relay has a wide control voltage range between 110 and 280V AC, so it's compatible with many electrical systems.

How do I check the operating status of this relay?

A built-in LED indicator gives the green light when your SSR is on for easy status monitoring.
