Connecting a Relay

09/15/2010 10:53 AM

I have a IDEC RY2S-UDV24V plug in relay DPDT RY2SU 24VDC and I and trying to wire it in to a circuit and I am lost as to how I need to connect the 8 pins into the socket. Is there anyone who can explain the relay diagram so that it will be easier for me to hook it up. I am not a electrical engineer and very knew to the circuit design and building stage. Any help would be greatly appreciated, thanks.

I have these documents printed oout, however I am unsure of the correct sequense in how to wires should be connected.

Then I think you need to hire a professional before you get hurt.

The reason I am asking is not to have someone be sarcastic but to help. Next time please keep you remarks of this site!

I agree with JRaef, pass this task off to someone that is qualified to perform this work.

Electrical work performed by un-qualified persons can be very un-forgiving i.e. property damage/loss, injury or death.

I don't have the socket, and was unsure how the blades of the relay could be wired directly into a circuit. I am far from un-qualified, I just haven't done this type up hook before.

The relay should fit into the socket only one way, send me the diagram and I can help, one side of the relay should be your coil, were your 24v go to, once you have 24v at your coil it should close the circuit and send power across your relay.

13 and 14 are your coil 24v or control voltage go to that 9 and 5 look to be normally open and so do 12 and 8, 24v pos and GRND go to 13 and 14 then when the relay makes (24v applied to the coil) power at 9 goes through to 5 same with 12 to 8 (in at 9 and out at 5 on to whatever.

Thank you very much. I will try as you suggested. It sounds like it is what I was looking for. If I run into any troubles, I will let you know. Thank you very much for the help.

If it's an American DPDT relay, it should have 8 pins. There is a "key" on the center "plug" so that it can plug into the socket only one way. The coil will be pins 2 and 7; pins 1-4 and 8-5 are NC; pins 1-3 and 8-6 are NO (pins 1 and 8 being common).

We don't yet know what needs to be NO and NC in your circuit(s).

I am trying to control a linear actuator to go down pause then go up. It is a custom project and there is know controller out there that will work so I am forced to build one. Any ideas out there would be greatly appreciated. And I thank everyone for their opinions even if they weren't helpful.

The particular relay you are trying to install is designed to be used with a socket.

If your application calls for a relay that can be wired directly into a circuit you are using the wrong type of relay.

I do not feel JRaef was being rude or sarcastic nor was it my intention to be by my comment about leaving this application to a qualified person but my case in point – you are using the wrong relay for your application, again, it is designed to be used with a socket.

Go back to the IDEC catalog and select the correct relay for your application. They sell relays with tails to be soldered directly into a circuit without the need of a socket.

Thank you, as I said I am new with working Relays. I will look at other realy that might be better suited for my application.

which linear actuator are you using? I have some experience with them.

It is a very old Linak. LA-30. This is a projhect for a hanicap person. The details of which I am not at liberty to discuss.

Will the application be mobile? You might want to look at the Linak CB8 battery/controller. If stationary, then I assume the relay will control the LA-30 directly?

IDEC designed this particular relay for both plug-in and solder connection, so it can be used with or without a socket.

This type of relay uses 2 separate sets of Form C contacts. The left set consists of terminals 1, 5 & 9, while the right set consists of terminals 4, 8 & 12. The description below applies to the left contact set. The right set works the same way.

Terminals 1 & 9 are normally closed (contact is made when there is no power to the relay coil). Terminals 5 & 9 are Normally Open (contact is made when the coil receives power).

Form C contact design is very widely used to simplify manufacturing and inventory processes. Because the same relay can be used whether your circuit design requires a normally open (NO) or a normally closed (NC) contact, you don't need to keep 2 different kinds of relays in stock.

Since you are not skilled at this: 1. Make sure the relay can handle the amperage draw of your actuator. An actuator is an inductive load, not resistive. The actuator will also have a "locked rotor" current draw which is much higher than running current draw (can you say safety factor). 2. Remember to install a clamping diode across the coil so that relay turn-off will not damage your driver circuit or power supply. Good luck !
