Description
12V 4 Channel Relay Module With OPTO Isolated Support High and Low Level Trigger Description: 1. Coil Voltage: DC 12V;Pole Number: 4 Channel 2. Load: 10A, AC 250V/125V, DC 30V/28V 3. The module voltage is 12V 4. Each way module can be set high or low triggered by jumper 5. Weight: 66g 6. Materials: Metal, Plastic, Electric Parts; Main Color: Blue 7. Has four mounting bolts holes, hole 3.1mm, 67mm x 44.5mm pitch 8. Module Overall Size: 7.3 x 5 x 1.8cm/2.9'' x 2'' x 0.7'' (LWH) 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 circuit , triggering the corresponding relay is low, while the high end of the short com high trigger.
Features:
- Optocoupler Driver Relay Module; Relay Type : SRD-12VDC-SL-C; 12V 4 Channel Relay Module power indicator ( green ) , 4 relay status indicator ( red )
- The module uses genuine quality relay , normally open interfaces Maximum load : AC 250V/10A, DC 30V/10A
- Using SMD OPTOCOUPLER isolation , driving ability , stable performance ; trigger current 5mA
- Interface design humane, all interfaces can be connected directly via terminal wiring leads , very convenient
- Fault-tolerant design , even if the control line is broken , the relay will not operate ; Has four mounting bolts holes , hole 3.1mm, 67mm * 44.5mm pitch
