The module uses genuine quality relay , normally open interfaces Maximum load : AC 250V\/10A, DC 30V\/10A; 2. Using SMD OPTOCOUPLER isolation , driving ability , stable performance ; trigger current 5mA; 3. The module voltage is 12V; 4. Each way module can be set high or low triggered by jumper ; 5. Fault-tolerant design , even if the control line is broken , the relay will not operate ; 6. The power indicator ( green ) , 4 relay status indicator ( red ) 7. Interface design humane, all interfaces can be connected directly via terminal wiring leads , very convenient 8. Module size : 73mm * 50mm * 18.5mm ( L * W * H ) 9. Has four mounting bolts holes , hole 3.1mm, 67mm * 44.5mm pitch Interface : 1. DC +: positive power supply ( voltage required by the relay , there 5V.9V.12V and 24V choice ) 2. DC-: negative power connection 3. IN1-IN4: each way based on the settings , can be high or low to control the corresponding relay outputs : a 12- line interface, the interface can be directly connected to all leads , user-friendly 1. NO1 - NO4: normally open relay interfaces , relay before the vacant after the pull shorted with COM 2. COM1 - COM4 Common Interface Relays 3. NC1 - NC4: normally closed relay interface relay shorted with COM ago , after the pull- vacant High and low trigger selection : 1.S1-S4 in order to relay a way -4 road high and low trigger selection ; 2.Com with low short ci\u003c\/p\u003e\n","brand":"LinkMejor","offers":[{"title":"Small","offer_id":55207470268788,"sku":"B00LW2GM84","price":7.39,"currency_code":"USD","in_stock":true},{"title":"Small (Pack of 2)","offer_id":55207470301556,"sku":"B0FRD384CW","price":7.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1007\/5799\/5892\/files\/719VuX-GPfL_e9bd036e-540d-4fbe-8122-1be23770820a.jpg?v=1787238571","url":"https:\/\/linkmejor.com\/products\/linkmejor-12v-4-channel-relay-module-with-opto-isolated-support-high-and-low-level-trigger","provider":"linkmejor.com - More for Less","version":"1.0","type":"link"}
