Relay Module With OPTO-Isolated High And Low Level Trigger

Using SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA;

Operating voltage DC 5-24V, 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)

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;

The module voltage is 5V,,12 V, 24V are available ;

Each way module can be set high or low triggered by jumper ;

Fault-tolerant design , even if the control line is broken , the relay will not operate ;

The power indicator ( green ) , 8/4/2/1 relay status indicator ( red )

Interface design humane, all interfaces can be connected directly via terminal wiring leads , very convenient

Module Interface :

1. DC+: 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 ;

2.Com with low short circuit , triggering the corresponding relay is low , while the high end of the short com high trigger
