Relay Module 4-channel relay, 5V low level trigger 10A contacts MT2502 Power consumption: 150mA +/- 10%This is a 5V 4 channel relay interface board, and each channel needs a 15 20mA driver current. It can be used to control various appliances and equipment with large current. It is equipped with high current relays that work under AC250V 10A or DC30V 10A. It has a standard interface that can be controlled directly by the microcontroller. Pin Description VCC: Positive supply voltage GND: Ground IN1IN4: Relay control port Output: Connect a load, DC 30V
