When the signal port is at high level, the normally closed contact of the relay will be closed. So you can connect and disconnect the load by controlling the level of the control signal port.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003e\u003cspan id=\"Pin_Description\" class=\"mw-headline\"\u003e\u003cb\u003ePin Description\u003c\/b\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003ch3\u003e\u003cspan id=\"Input:\" class=\"mw-headline\"\u003eInput:\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eVCC:\u003c\/b\u003e Positive supply voltage\u003cbr\u003e\n\u003cb\u003eGND:\u003c\/b\u003e Ground\u003cbr\u003e\n\u003cb\u003eIN1--IN4:\u003c\/b\u003e Relay control port\u003c\/p\u003e\n\u003ch3\u003e\u003cspan id=\"Output:\" class=\"mw-headline\"\u003eOutput:\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eConnect a load, DC 30V\/10A，AC 250V\/10A\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003e\u003cspan id=\"Features.EF.BC.9A\" class=\"mw-headline\"\u003e\u003cb\u003eFeatures：\u003c\/b\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSize: 75mm (Length) * 55mm (Width) * 19.3mm (Height)\u003c\/li\u003e\n\u003cli\u003eWeight: 61g\u003c\/li\u003e\n\u003cli\u003ePCB Color: Blue\u003c\/li\u003e\n\u003cli\u003eThere are four fixed screw holes at each corner of the board, easy for install and fix.
