2-channel module with relays designed to work with the Raspberry Pi Pico. It can switch signals up to 250 V AC and 7 A or 30 V DC and 10 A. SB Components 21284

This SPST solid-state relay module allows for safe switching of DC circuits up to 30 V and 11 A, offering galvanic isolation and low conduction resistance (approx. 30 mΩ) thanks to the use of back-to-back MOSFET transistors. It features fast switching time (up to 1 ms), low control current consumption (approx. 10 mA), and the ability to control a signal from 2.7 to 40 V. Its compact design, lack of mechanical components, and the ability to mount on 2.54 mm connectors or screw terminals make the module a durable and quiet solution for systems requiring reliable insulation and long service life.
