2 Channel Relay Shield for Arduino Nano

2 Channel Mini easy to use Relay shield for Arduino Nano consists of ULN2003 IC and 2 Mini 12V Relays with NO/NC contacts of 2A-24V Load Capacity. ULN2003 used as Relay coil driver. Relay can be controlled from D3 and D4 of Arduino Nano. Three-pin Header Connector CN1 and CN2 provided to connect the Load. Relay has normally open and normally closed contacts with 2A and 24V capacity and also can handle 120V AC but it’s not advisable. CN2 supply input 12V DC. LED D2 and D3 are the output LEDs.

Features

• Supply 12V DC
• Relay Load 2A-24V DC (120V AC Possible with Care)
• Relay Switch Normally Closed/Normally Open
• On Board LED D2 and D3 Operation Indicator
