Description: 12V 4 Channel Relay Module with OPTO-Isolated Support High and Low Level Trigger 12V 4 Channel Relay Module Using SMD OPTOCOUPLER isolation High and Low Level Trigger Description 12V 4 Channel Relay Module With OPTO-Isolated Support High and Low Level Trigger 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 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 ; 2with low short circuit , triggering the corresponding relay is low , while the high end of the short com high trigger Shipping We ship within Three business days of payment, usually sooner.
