The module with 4 relays is designed to work with Arduino. It allows you to control devices with operating parameters up to 250VAC/7A or 30VDC/10A. Seeed Studio 103030009

The module contains four 5V relays with a maximum current of 10A (250 VAC) and opto-isolated inputs, and with jumpers it is possible to select switching with high or low status. The module is equipped with screw connectors. modRL04_ISO

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. Pololu 5420

Module with 5 A 250 VAC relay. DFRobot DFR0017

Module with a 12 V relay and a timer. It allows you to turn the device on and off cyclically at a specified time using potentiometers. It can also operate in single trigger mode, which allows the device to be turned on after a signal has been applied for a specified period of time. The operating time can be adjusted from 1 s to 100 s or from 1 s to 15 min
