2 channel relay module

Features:

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 5V, 9,12 V, 24V are available ;

4.The module can be set to 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 ) , relay status indicator ( red )

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

8.Module size : 50mm * 41mm * 18.5mm ( L * W * H )

9.Has four mounting bolts holes , hole 3.1mm, 44.5mm * 35.5mm pitch

Interface: 1. DC +: positive power supply ( voltage required by the relay , there 5V.9V.12V and 24V choice )

1. DC-: negative power connection

2. IN1: 1 channel signal to trigger the end , you can set a high or low level control relay

3. IN2: 2 -channel signal to trigger the end , you can set a high or low level control relay

Outputs: 1. NO1: After a relay normally open interfaces , relay before floating, shorted pull with COM1

1. COM1: 1 relay common interface

2. NC1: 1 relay normally closed port, COM1 relay shorted before and after the pull- vacant

3. NO2: 2 -way normally open relay interface, the relay before floating , pull back and COM2 short

4. COM2: 2 Common Interface relay

5. NC2: 2 -way normally closed relay interface relay short front and COM2 , pull vacant post

High and low trigger selection:

1.S1 as a relay trigger selection of high and low ;

2.S2 high and low for the two -way relay trigger selection

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