SSR-40DD 40A DC Output Solid State Relay-Ampflick

Description

SSR-40DD 40A DC Output Solid State Relay-Ampflick is a relay module built to let low-power microcontrollers safely switch high-voltage devices like lights, fans, and appliances.

It offers optocoupler isolation to protect your controller, onboard status LEDs, and flyback diode protection for inductive loads.

It’s the go-to part whenever a project needs to safely control something running on mains voltage.

A safe, reliable bridge between your logic circuit and the real world.

As part of our General Hardware & Accessories range, this component is sourced and checked for consistent quality before it ships, so what you order is what you get. We stock it specifically because parts used in a wide range of hobbyist and production projects need to work the first time, every time, whether you’re building a one-off prototype or a batch of finished units. Fast dispatch and fair pricing mean you can keep your project moving without overpaying for basic components. If you run into any questions about compatibility or specifications before ordering, our team is happy to help you choose the right part for your build.
