HiLetgo 12V 8 Channel Relay Module with OPTO-Isolated High and Low Level Trigger 8 Ways Relay Switch Module for Arduino
<b>Description : </b><br>1. The module uses genuine quality relay , normally open interfaces Maximum load : AC 250V/10A, DC 30V/10A; <br>2. Using SMD OPTOCOUPLER isolation , driving ability , stable performance ; trigger current 5mA; <br>3 . The module voltage is 5V, 9,12 V, 24V are available ; <br>4 . Each way module can be set high or low triggered by jumper ;<br>5 . Fault-tolerant design , even if the control line is broken , the relay will not operate ; <br>6 . The power indicator ( green ) , 8 relay status indicator ( red ) <br>7 . Interface design humane, all interfaces can be connected directly via terminal wiring leads , very convenient <br>8 . Module size : 141.5mm * 50mm * 18.5mm ( L * W * H ) <br>9 . Has four mounting bolts holes , hole 3.1mm, pitch 136mm * 44.5mm <br><br><b>Module Interface :</b><br>1. DC +: 12V positive power supply <br>2. DC-: negative power connection <br>3. IN1-IN8: each way based on the settings , can be high or low to control the corresponding relay <br><br><b>Relay outputs :</b>24 line interface, the interface can be directly connected to all leads , user-friendly <br>1.
