Third channel on RS80D controller

Hi all

i bought the RS80D controller from the states for my new crusher it has channels and i can use it for other stuff that why i got it

anyway the third channel i was planning to use for the wepon controller but with conversations with GRant it doesnt seem possible can anyone see a way to do it?

a link to the site with specs

thanks alex

btw i have e-mailed them but they dont seem to be very helpful

It depends on how you want to use it. You could cascade that third channel with a bigger relay for instance and have that power the crusher. I wouldnt try to run the crusher straight from that third channel.

btw, I think the RS80D is a nice controller. If I hadnt bought the Sidewinder first I probably would have went for that one.

As said, its easy enough to ad relays from that but with it only being a 2 position switcher as far as I can see you can only have up/down with microswitches at the end with no stop in the centre

no it is 3 postition (forward - off - rev)

copy & paste of manual.

Normal PWM
This mode is straight R/C pulse to PWM with dead-band, variable brake and variable
acceleration support. Note: Exponential curve does not apply to the Auxiliary channel.

Spin Controller
Auxiliary spin control, selected with Mode Switch A1 in the ON position, modifies the
standard forward/reverse PWM mode for unidirectional operation and variable brake.
Forward stick gives 0-100% forward powers while reverse stick gives 0-100% braking.
Furthermore, with loss signal (broken cable, dead radio, dead transmitter) full braking is
applied at once. Spin control uses the AUX ACCEL control input, but does not use the
BRAKE input.

Relay controller
Auxiliary relay control, selected with Mode Switch A0 and A1 in the OFF position, drives
the AUX controller as a bi-directional relay with Limit switch support. This can be used
for non-servo lifter systems. The operation is as follows:
Stick neutral Coast
Stick ½ forward 100% forward
Stick ½ reverse 100% reverse
Loss of signal 100% brake

So ...it seems to me that you can use the third RS80D output to control ...via the PWM signal... an ESC ...or Relays.

If its a 3 position then it will work fine - I must have missed that part!

Now that i have the third channel situation sorted now i need the realys in order to control the linear actuator, i am unsure on this topic so any advice would be great ie

what sort?
any specs?
where to buy?

By the way i have tried to search my self but i am unsure what to get

Thanks Alex

what sort?
any specs?
where to buy?
...Those questions first require an answer to this question.

What load / motor are you going to have?

Well the linear actuator i will be using is the Duff Norton Minipac which is a 12volt motor but i will run near 24v

stalled on max load.
7.2v - 12.5A
14.4v - 25A
21.6v - 38A

if you need any other info please ask

thanks for the help

Alex

A pair of relays from technobots should be fine.
24V SPCO 30/40A Relay - Part No: 1600-002

cheers Woody

how would i go about wiring the 2 relays?


Thanks Alex

Sorry Alex ,
Ive read what information I can find and still havent a clue .

Are these the same relays as on the electronizes?
They do not have a center off setting do they?

They dont have a center off ( Neutral ) as in three seperate postions ON Neutral OFF ...No.
Do you know of any that do Leo?

They can as a pair be configured to give three options.
OFF OFF ( Neutral / Brake ) ... OFF ON and ON OFF.

The missing ON ON option is the same as OFF OFF

Well if the RS80D aux channel works as i think it does, Then I think I have the schematic for Alex.

Well if the RS80D aux channel works as i think it does...thats the prob ...Im not sure what the Aux is putting out in relay mode.

Neither did I, so i sent them an email asking them. Their answer is somwhat disturbing.

quote:

The Aux channel is not made to connect to relays. It is designed to interface to a OSMC or MC1 motor controller to control a third motor.This information I couldnt find in the manual or the website.

So ...It would seem that Alex is back to the use of a std switcher via the receiver.

Or an ESC, either way, the third channel on the RS80D is not very usefull unless you still have osmcs lying around like me. But then buying a RS80D would be pointless since I might as well use the OSMCs then.

Use a home made H bridge whit simple relays and a speedo that can give two relay signals out on one stick, on forward and on reverse as the IBC, BUT it is 12 volts for forward and 5 for rewers so you have to build a H bridge whit both 12 AND 5 volts relays.

maximum relay current draw on their coils 100 mA, see IBC specs on

A pice of the specs:

TWO x Auxillary Relay Outputs to trigger your Weapons from your controls. Want more than a wedge-bot? You will need a 3rd Radio Control channel to activate that flipper, spinner or other weapon. The IBC will decode that 3rd channel into *two* relay outputs. One for stick-forward, and one for stick back. Dual Controls are here. How many weapons and arms can you think of for you bot with this feature? Comes with the cable you will need to activate these AUX controls.
