Product Description

The CRYDOM Solid State Relay (MPN A2490) is a panel-mounted, AC-output relay with a Form A (SPST-NO) switch configuration. It operates with an input current of 10 mA and an output voltage range of 24 to 280V AC, featuring a screw-clamp electrical connection. This relay is not finger-safe and is not recommended for use without a heat sink.

Frequently Asked Questions

What is the CRYDOM A2490 solid state relay used for?

The CRYDOM A2490 solid state relay is used for switching AC loads in industrial automation, HVAC, and process control systems. It provides reliable, silent switching with no moving parts, making it ideal for high-cycle applications where electromechanical relays would wear out quickly.

What are the specifications of the CRYDOM A2490 solid state relay?

The CRYDOM A2490 is a panel-mounted, AC-output solid state relay with a maximum output current of 90 A and an output voltage range of 24 to 280V AC. It uses a screw-clamp connection, requires 10 mA input current, and is not recommended for use without a heat sink.

Where to buy the CRYDOM A2490 solid state relay worldwide?

You can source the CRYDOM A2490 solid state relay through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring the relay reaches your facility efficiently.

How to install the CRYDOM A2490 solid state relay?

Mount the CRYDOM A2490 on a panel using the appropriate hardware. Connect the AC load to the output terminals via the screw-clamp connections, and apply the 10 mA DC input signal to the control terminals. Always install an adequate heat sink, as operation without one is not recommended.
