Your cart is empty. 12V 4 Channel Relay Module With OPTO-Isolated Support High and Low Level Trigger
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 ) , 4 relay status indicator ( red )
7. Interface design humane, all interfaces can be connected directly via terminal wiring leads , very convenient
8. Module size : 73mm * 50mm * 18.5mm ( L * W * H )
9. Has four mounting bolts holes , hole 3.1mm, 67mm * 44.5mm pitch
Interface :
1. DC +: positive power supply ( voltage required by the relay , there 5V.9V.12V and 24V choice )
2. DC-: negative power connection
3. IN1-IN4: each way based on the settings , can be high or low to control the corresponding relay
outputs :
a 12- line interface, the interface can be directly connected to all leads , user-friendly
1. NO1 - NO4: normally open relay interfaces , relay before the vacant after the pull shorted with COM
2. COM1 - COM4 Common Interface Relays
3. NC1 - NC4: normally closed relay interface relay shorted with COM ago , after the pull- vacant
High and low trigger selection :
1.S1-S4 in order to relay a way -4 road 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

These relays are compact, timing function works just fine, Indicator LEDs are bright, used to switch 24vdc works great. Terminals are close because of compact size.

If you're even mildly electrically inclined, this is pretty simple to set up. The operation of it is pretty simple. I had originally used this in an open auto pro setup, but decided to switch over to a four-channel opto coupler board instead, another there was anything wrong with us at all. It works really well and does what it's supposed to do. This board would also be a better option if you are trying to control higher voltages, as the optocoupler boards circuit is not designed to have a significant amount of current running through it. Something to keep in mind!

This is a great compact board and a good value at $7. Be aware however that the inputs may not be assigned to the relays as labeled. On my board input 1 actually controlled relay 2; input 2 controlled relay 1; input 3 controlled relay 4; and input 4 controlled relay 3. So check your board to confirm which inputs control which relays. Otherwise the board worked as expected. But for this quirk this would be a five star item.

Some of the relays didn't worked or stopped work with the no reason. The problem is the jumpers that don't do a good contact. Since I replaced the jumpers or make it permanent I don't have any other problem.

I run a haunted house and use this product for a lot of our automated props and have never had an issue.

There are a few other brands and they are nowhere as good. I have some of these in the field and they have been working for years. The ability to switch the high/low trigger with a jumper is ESSENTIAL! Do not buy one unless it has that feature.

I have it installed and wired works like a charm
