2-channel SSR 240V / 2A relay module with fuse

Module with 16 relays with a maximum switching current of 7 A. It communicates via a USB interface. Numato Lab RL160001-24

Module with 2 relays with a maximum switching current of 7 A. Equipped with the ATmega328P microcontroller, it can be programmed in the Arduino IDE. Numato Lab PRLY001

This SPST solid-state relay module allows for safe switching of DC circuits up to 60 V and 7 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 isolation and long service life.
