{"title":"Relay Shield v1.1","handle":"relay-shield-v1-1","url":"/products/relay-shield-v1-1","description":"The Relay Shield v1.1 is an Arduino compatible smart module with 4 mechanical relays providing an easy way to control high voltage. The max switching power is 35VDC 70W for each channel. It can be directly controlled by Arduino/Crowduino through digital IOs with external 9V DC supply. Compared to the Relay shield1.0, the v1.1 version use 4 selector instead of those push buttons used on version1.0, to make it more convenient to control the relays manually.Note: Please note that the pins on relay shield should not touch the USB connector of Arduino UNO when they are connected.Features\nArduino,Crowduino, Arduino Mega compatible\nAutomatic control and manual control\n4 mechanical relays with photo-coupled circuit\nEquipped with screw holes for easy installation\nLight weight\nSmall form factor\nExtendible\nSpecification\nVoltage: 7~12V\nCurrent: 8~250mA\nSwitching Voltage: Max 35V\nSwitching Current : Max 2A\nFrequency Response: -1~1dB\nSwitching Power: Max 70W\nRelay Life: > 100000\nCautionPlacing 2 layers of electrical tape on the top of the Arduino's usb connector will prevent the relay shield from making contact. Do not operate voltage more than 35V DC.Package listRelay shield PCBA x1Wiki & External linksWiki","vendor":"Elecrow","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4031,"title":"Default Title","sku":"EC-MCS01584R","price":14.14,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":109,"option1":"Default Title"}]}
