4 Channel 5V Relay Module

Module with 8 relays with a voltage of 12 V and a load of up to 10 A. The board communicates via the Ethernet interface. Numato Lab 8ETHRL001

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.

Module with 8 SSR relays with a load of up to 3 A. The board is equipped with the ULN2003 system and communicates via a digital interface. Numato Lab SSRC80001-DC

Module with 16 relays and 8 analog inputs. Communicates via the WiFi wireless interface. Numato Lab WFRL160001

Pololu 5425 offers silent, reliable operation when switching currents up to 10 A and voltages up to 30 V, providing galvanic isolation and full configurability of RC control parameters. The version without soldered connectors allows easy adaptation to individual mounting needs in RC and automation projects.

Module with four 240V/2A relays controlled by 5V with a fuse triggered by a high state. modSSR-4CH-H

The module with SSR BT136S relay with a load of up to 2 A, designed for M5Stack sets. The board is equipped with a Grove connector and is controlled by a digital input. M5Stack U122

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.
