Solid State Relays are electronically activated switches that are capable of controlling high-voltage electrical loads. They can be used for a variety of applications, including automated control of lighting, HVAC systems, motors, pumps and microwaves. A2490E-B is one of the most commonly used and popular Solid State Relays, with an integrated plated mounting base and novel design.

A2490E-B Application Field

A2490E-B is a versatile and high-performance solid state relay that can be used in a variety of applications. It is ideal for applications where space is limited or where a high degree of flexibility is needed. Common applications for the A2490E-B include motor control, automotive, lighting control, HVAC, pumps, and microwave ovens.

Working Principle of A2490E-B

At the heart of the A2490E-B is its Opto-isolated solid state switch. This switch is composed of an input side optical isolator, an output side solid state switch, and three optically-coupled transistors. When current is applied to the input side of the device, the optical isolator takes in the current and converts it into light. This light then triggers the output side switch, causing it to close and allow current to flow through the device.

In addition to this, the A2490E-B also features an integrated mounting base, which makes installation and set-up faster and more convenient. The mounting base is plated with a tough, corrosion-resistant material that helps it to last longer and protects against wear and tear and electrical surges.

Advantages of A2490E-B

The A2490E-B is a reliable, versatile and cost-effective solution for applications that require a high degree of flexibility. It has a compact size, as well as an integrated mounting base, which makes installation and set-up easier. Additionally, it has excellent electrical characteristics, with a low on-state resistance, a high input-to-output isolation voltage, and a wide control voltage range. Finally, it is also highly reliable, with a long life span and an excellent MTBF (mean time between failures).
