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/9V/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 * 40mm * 16mm (L * W * H)
9. Has four mounting bolts holes, hole 3.1mm
Interface
1. DC+:Positive power supply (voltage required by the relay, there 5V/9V/12V/24V choice )
2. DC-:Negative power connection
3. 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
NO1:After a relay normally open interfaces , relay before floating, shorted pull with COM1
COM1:1 relay common interface
NC1:1 relay normally closed port, COM1 relay shorted before and after the pull- vacant
NO2:2 -way normally open relay interface, the relay before floating, pull back and COM2 short
COM2:2 Common Interface relay
NC2:2 channel normally closed relay interface relay short front and COM2, pull vacant post
High and low trigger selection
S1 as a relay trigger selection of high and low
S2 high and low for the two -way relay trigger selection
Comes with low short circuit, triggering the corresponding relay is low, while the high end of the short com high trigger
High and low trigger selection
Short jumper with LOW triggered when connected
When the jumper is high with high short trigger
