Can someone post a picture on the actual relay that i need to use to control various equipment? i ned to drive a lift and a screen up and down
thank you

Need more information, Is the screen motor AC or DC and what voltage is it?

its AC 230V 50Hz

so im guessing it is less than 1A, if your asking these kinds of questions , i would recomend that you get a electrical engineer to wire this up for you, you need to wire the relays up so that both can not be powered up at the same time, as this will blow the motor.

i'm guessing i would just wire the relay to the extender and then try open/close to and measure the output

i just dont know what kind of relay i need to get. i ve been told there are stand alone and some on pcb boards ready made so dont know what i should be looking at

If i'm not mistaking teh relay operate only DC currents (has a filter so non-dc signals pass past the relay).

Anyway the voltage is too high for the relay (supports only up to 48V). You can use it only as a "driver relay" for something more appropriate for your screen.

As gopronto said you need 2 one for up and one for down. And never close both relays at the same time it will damage your motor. One has always to remain open, while the other is closed.

but the support up to 48vdc is to drive the relay. thats not an actual relay right?

you wire the rfx into a relay which accepts control of up to 48vdc. the operation voltage is another story. you program the rfx to send the voltage and open close the circuit of the relay right?

No, you can't drive the relay, the RFX9600 drives all the relays. The 48VDC 1,2A max are the actual applicable voltage and current to the switch pins of the integrated relays. Use one of the relays to drive a 230V line and the results can be disastrous, as the relays are not made for it. Especially because they can only handle DC, because as explained above, the output of the relays has a filter built in to allow only DC (it has a small capacitor built in between the two lines).

I'm not sure i'm following you.

You can use the provided relay outputs in conjunction with the supplied 5V source on the rfx (or another source up to 48V) to drive another relay, that is not built in the RFX but does the heavy lifting with the power lines. The relay you'll be controlling with the RFX's relay mus be operated (driven) with a voltage that is less than 48 V (limitation of the RFX's relay) and the current consumption of the driving coil must not exceed 1,2A or 300mA if you're using the RFX's 5V supply.

You don't program any voltage the RFX's accept commands to open or close the relay

CF.extender[x].relay[x].set(true) - close the relay
CF.extender[x].relay[x].set(false) - open the relay

You can use any relay, whose coil is driven with a voltage from 5V to 48V DC and that when the coil is in operation the current doesn't exceed 1,2A (or 0,3A if using the RFX's built in supply). Choose the type of output that you need. Either buy a stand alone (like a DIN rail mountable relay) or on a PCB with provided connectors. If you're using the RFX's relay to drive another relay don't forget the discharge Diode on the terminals of the driven relay.

can you check this relay? i got one of these but the 230v version. it uses 24vdc to open close the circuit for which the load is 230vac

isnt this what i should be using?

Yes this should do it. But before you use it please measure the resistance of the coil (with an ohm meter) and then see what current it draws with the equation

I = 24V / (measured resistance). If the number exceeds 1,2A it's not good.

Anyway to drive a screen up and down you need 2 of those, each for one operation and as mentioned neither should be on at the same time.

Please note that if you're not a trained electritiain or have some electronic knowledge and by using info provided in this thread nor I or any of the other participants in the thread can be held responsible for any damaged equipment. Just to be on the safe side :).

thank you clear!

i have added 2 buttons for opening and closing the 2nd relay. Do i need to regulate the voltage? i mean how do i make to output 12volts? i connected it on the relay but nothing happens

Please do not go any further doing this... you are worrying me, your saftey could be at risk.. please get someone in who knows what they are doing !

The relay have to be wired correctly so that power CAN NOT ! be switched to up and down at the same time....

I think it will be easier for you. Open the link.

its ok i thought the outputs on the pronto provide voltage as well didnt think that the 12v need to be from an outside adapter. so i linked an old hard disk charger and managed to close/open the loop
