This module has the advantage of being remote controlled and having four relays that work on a voltage of 12 V with a very small current draw of 5mA.
This module allows you to control high voltage devices, like the home appliances, using a 5V signal. The relay module is capable to work with voltages up to 250 VAC and supports currents up to 10 A, making it ideal for home automation.
This module has advanced quality timing chip control and accurate timing performance commonly used in car modification, motor control, light bulbs, LED lights, DC motors, micro-pumps, solenoid valves and other equipment.
This relay module with a light sensor can be used as a light detector and brightness detector through the potentiometer. It can be used to control a variety of street lights that automatically open at night and during the day automatically off, vehicle control and automation equipment.
This is the Power Relay FeatherWing. It gives you power to control, and control over power.
Relay Module with 5A Overcurrent Protection (12 V Power Supply)
This product is a module with 1 solid state relay useful for medium power AC applications. The relay resists up to a voltage of 250 V, alternating current at a frequency of 50 Hz - 60 Hz. The maximum current it holds is 2 A.
This is a very common Contact Relay for control VAC 110/220V (10A) and VDC 30V (10A) power.Control pin of Relay connected to I/O D1. You can change connection to other I/O, just need cut off of connection D1 and do solder to other connecting pads.For work of Relay need power IN 5V.
