SSR 240V/2A relay module with fuse

Module with 4 5 V relays with a maximum switching current of 2 A. It communicates via the USB interface and does not require an additional power supply. Numato Lab USBPOWRL004

Industrial module with 8 relays. It communicates via RS485 interface and supports Modbus RTU protocol. Waveshare Modbus RTU Relay (EN)

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.
