OpenJumper OJ-XM1139 4-CH Relay Module for Arduino

Features:

.4-CH digital relay module provide 4-CH input and output, Can connect Max. 30V10A or AC 250V 10A devices to control electric lamp and electrical machine, etc
.Contact: Each channel with normally open contact and normally-closed contact,DC30V 10A or AC 250V 10A
.When using the Arduino do interactive projects, many large current or highvoltage equipments cannot use Arduino digital IO port to control directly (suchas solenoid valves, lights, motors, etc.), you can consider to use relay schemeto solve
.Great for DIY project
