Description
HiLetgo 5V 1 Channel Relay Module With OPTO Isolation Support High or Low Level Trigger Product description： 1. 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 12 V; 4. The module can be set to 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 ) , relay status indicator ( red ) 7. Interface design humane, all interfaces can be connected directly via terminal wiring leads , very convenient 8. Module size : 50mm * 26mm * 18.5mm ( L * W * H ) 9. Has four mounting bolts holes , hole 3.1mm, 44.5mm * 20.5mm pitchInterface : 1. DC +: positive power supply 12V 2. DC-: negative power connection 3. IN: can be high or low level control relayRelay outputs : 1. NO: normally open relay interface, the relay before the vacant after the pull shorted with COM 2. COM: Common Interface Relays 3. NC: normally closed relay interface relay shorted with COM ago , after the pull- vacant High and low trigger selection ends : 1 short jumper with LOW triggered when connected ; 2 When the jumper is high with high short trigger .
