Relay Module 5Vdc – 8 Relay Arduino & MCU H/L Trigger

Specification:

• Maximum load: AC 250V/10A, DC 30V/10A for each relay
• Driving current for each relay : 20mA
• Working voltage: 5V
• Module size: Size: 4.4cm x 13.8cm x 1.85cm (L x W x H)
• LED Indicators
• Optocoupler Isolation
• High or Low Trigger Selection 

Module interface:

• VCC: positive power supply (VCC) 5Vdc
• GND: negative power supply (GND)
• IN1 ~ IN8: control signal for relay 1 ~ 8

Very good to use it with motor switching control or pump starting applications with your microcontrollers , arduino boards or PC port.
