Module size :  13.8*5.6*1.80cm\/5.43\"*2.20\"*0.71\"( L * W * H ) With 4 fixing bolt holes , hole 3.1mm, pitch  131mm * 49.5mm Finished by 100% functional testing and  stability testing Two module interface : 1, VCC: 5V power supply connected to the positive 2, GND: 5V power supply connected to the negative 3, IN1-IN8: trigger signal , active low Relay outputs : a 12- line interface, the  interface can be directly connected to all leads , user-friendly 1, NO1 - NO8: normally open relay interfaces , relay before the vacant after  the pull shorted with COM 2, COM1 - COM8 Relay Common Interface 3, NC1 - NC8: normally closed relay interface relay shorted with COM ago , after  the pull- vacant Quantity:1Pc Size for manual  measurement, there may be a 0 to 2 cm error, belongs to the normal phenomenon. And due to the difference between different monitors, the picture may not  reflect the actual color of the item. Thank you! 1Pc x Module.3, NC1 - NC8: normally closed relay interface relay shorted with COM ago, after the pull- vacant. 1, NO1 - NO8: normally open relay interfaces, relay before the vacant after the pull shorted with COM.\u003c\/p\u003e","brand":"Shop2IndiaBei","offers":[{"title":"Default Title","offer_id":43043380986024,"sku":"U2I-1-401210816058","price":1911.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0300\/1588\/1354\/products\/s-l2000__18711_7e0d6d24-5958-4844-a35f-834acb6ce13c.jpg?v=1672766882","url":"https:\/\/shop2india.com\/products\/5v-relay-8-channel-shield-module-board-optocoupler-module-for-arduino-arm-avr","provider":"SHOP2INDIA GATEWAY","version":"1.0","type":"link"}
