Description

HiLetgo 12V 8 Channel Relay Module with OPTO-Isolated High and Low Level Trigger 8 Ways Relay Switch Module for Arduino
12V 8 Channel Relay Module With OPTO-Isolated High And Low Level Trigger
The module Operating voltage 12V;
The module can be high or low by a jumper setting trigger;
Fault-tolerant design, even if the control line is broken, the relay will not operate;
The power indicator (green), the relay status indicator (red).
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 ) , 8 relay status indicator ( red ) 7 . Interface design humane, all interfaces can be connected directly via terminal wiring leads , very convenient 8 . Module size : 141.5mm * 50mm * 18.5mm ( L * W * H ) 9 . Has four mounting bolts holes , hole 3.1mm, pitch 136mm * 44.5mm Module Interface :1. DC +: 12V positive power supply 2. DC-: negative power connection 3. IN1-IN8: each way based on the settings , can be high or low to control the corresponding relay Relay outputs :24 line interface, the interface can be directly connected to all leads , user-friendly 1. NO1 - NO8: normally open relay interfaces , relay before the vacant after the pull shorted with COM 2. COM1 - COM8: Relay Common Interface 3. NC1 - NC8: normally closed relay interface relay shorted with COM ago , after the pull- vacant High and low trigger selection : 1.S1-S8 in order to relay a road -8 way 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 Package Included:1*12V 8 Channel Relay Module With Optocoupler
