Need help with wiring

Hi need help wiring relays to the prop 1 because all the RC-4s are gone thanks  :)

JackMan

Relays are easy but we need to know specifics on exactly what you want to accomplish.  ;)

I want to hook up some drills that plug in, and some lights, and two fog machines, a trigger audio bord, and a solenoid for my air cannon

JackMan

Well, you're really not providing enough information. Are your devices AC or DC or both? Exactly how many of each device? What's the current draw of your solenoid? (it may not need a relay). What audio board? Basically a relay coil would connect to V+ and OUTx on the Prop-1. Typically you want the relay coil to be the same voltage that you are powering the Prop-1 with. Again, we really need more specifics on exactly what you want the Prop-1 to do and what your devices are.

The Solenoid is 24V, I have 2 drills both AC and 2 fog machines that I modified the remotes so it could connect and run with relays, also a 18 ch trailerable  sound bord http://www.solarbotics.com/product/50750/ and I what to run this all from the prop 1 originally I was going to get some of efx tech's I/O bords with relays but there all sold out so I hope this is more info I'm new to prop controls, and also I'm wondering what is the best relays to use thanks  :)

I would suggest these connections:

P7 - Serial output to player
        -- transmit only
        -- requires player configuration to 2400 baud

P6 - Trigger Input

P5 - Not assigned

P4 - Relay for Fogger #2
        -- requires 24VDC coid, 3W or less

P3 - Relay for Fogger #1
        -- requires 24VDC coid, 3W or less

P2 - Relay for Drill #2
        -- requires 24VDC coid, 3W or less

P1 - Relay for Drill #1
        -- requires 24VDC coid, 3W or less

P0 - Solenoid
        -- requires 24v power supply
        -- must be 3W or less


Inexpensive 24V relays are not easy to find; I almost want to suggest you change the solenoid coil to 12V which simplifies the rest (12V supply and relays for your outputs).

Here's one possibility that's cheap, though it looks like you may have to solder wires to it.

This one would be easier to wire up, though it costs 5x the one above.

http://www.allelectronics.com/make-a-store/item/RLY-2024/24-VDC-DPDT-10-AMP-RELAY/1.html

I've attached a generic schematic for controlling an AC device using a relay that is controlled by the Prop-1. Note that you can also use a relay to control very high-current DC devices (like windshield wiper motors).


Your audio player -- as long as you have the right firmware -- can be configured to work at 2400 baud which is the max baud rate of the Prop-1.

ok thanks now do I need a relay bord or should I just solder the wires to them and would the relay bord need to be I/O and what do I do for the audio bord no relays at all???? thanks for all the help

I am going to add on to Jack's point here and answer your question.

It all determines what type of relays you plan on using, solid state or mechanical. Solid state relays are a little different than mechanical relays. Since some solid solid state relays come in two versions DC(Transistor) and AC(back to back SCRs) and most them use a relay board which the solid state relays are inserted into and some use screw terminals. Mechanical (aka, electro-mechanical) which doesn't mater what type of voltage (AC or DC) that you apply to the relay contacts and use screw terminals when used with it's socket (blade or octal).

Another thing to remember is to know much load (current) that you are going to run through these relays that you chose to use. A basic plug-in (blade or octal) mechanical ones can handle around 10 amps @28VDC or 120VAC and the more current you need the more pricey they get and than they aren't consider plug-in types any more. Now, the solid state relays are limited in the current department around 10 amps AC or DC and the more amps you need the bigger and pricey they get.

Look in the Docs section of these forums under the Prop-1 and you find the Prop-1 PDF which should you how to connect your relay or lamps up to the Prop-1 outputs.

Remember to provide all the details on what type relay you plan on using and we can provide more detail answer to you.

Thanks for everyones help I think I'm good to go! Thanks agin  :D

You don't need a relay for your audio board, as Jon mentioned, it's controllable with a serial connection from the Prop-1. Just want to make sure you understand that any soldering or other connections that you make with 120V AC need to be in some type of protective encloser as bare line voltage is extremely dangerous.
