Module with 2 relays 12 V with a maximum switching current of 7 A. Numato Lab RL20002

16-channel PoE module with relays allowing you to connect your PC to other electronic circuits via the network. It does not need a separate cable for power and data transmission. It can be controlled via a simple web interface or Telnet. Numato Lab NLRP1002-A

ModRL01 module with 10A/250VAC (10A/24VDC) relay, supply of 5 V load relay coil, additional control circuit, protected overvoltage control

Module with one 5 V relay with a maximum switching current of 10 A. It communicates via a USB interface and does not require additional power supply. Numato Lab NLRL1001-A

A magnetic latching relay that features low power consumption and quiet operation. It allows switching of signals up to 36 V and 10 A. It remains in the last position it was in before power was lost. DFRobot DFR0996

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

The remotely controlled modulation module MOD-34 / AZ allows wireless load control with up to 10 A current consumption via a relay. It does not contain nRF24l01.

The module with 4 relays, designed to work with the micro:bit. It allows you to control devices with operating parameters up to 120VAC/2A or 24VDC/2A. SB Components 14118

4-channel switch module with a maximum voltage of 16 V and a current of 2 A based on a MOSFET transistor. It is controlled by digital inputs. It is equipped with a screw connection and status LEDs. Adafruit 5757

Board with the WiFi ESP-12F (ESP8266) module and a 5 V relay. Equipped with an AC adapter

Module with 4 relays with a maximum switching current of 7 A. Equipped with the ATmega328P microcontroller, it can be programmed in the Arduino IDE. Numato Lab PRLY002

2-channel module with relays, designed to work with the Raspberry Pi. It can switch 250VAC/7A or 30VDC/10A signals. SB Components 14088

4-channel module with relays, designed to work with the Raspberry Pi. It can switch 120VAC/2A or 24VDC/2A signals. SB Components 14071

This module allows independent control of two Omron G5LE-14-DC5 SPDT relays, supporting currents up to 10A. Thanks to built-in BSS138K MOSFETs, it can be controlled directly from 3.3V or 5V development boards such as Arduino or Raspberry Pi. Each channel is equipped with an LED to indicate relay activation and 5mm screw terminals for convenient circuit connection. Pololu 5665

The module is equipped with eight 10A / 250VAC relays controlled independently via a serial bus (UART) or from a PC (through a microUSB connector). The NO / NC contacts of the relays have been led to the ARK screw terminals. The board recommended for use with Arduino enables the control of eight relays using only two microcontroller lines. ICSTATION ICSE014A

The Pololu 5423 module provides reliable load control in RC systems with full galvanic isolation. The SPST solid-state relay supports up to 6 A at voltages up to 60 V and is suitable for applications requiring silent operation, durability, and precise control using RC signals. The version without soldered connectors offers flexibility for adaptation to individual projects.
