Is my relay box PWM or analog

Post by madweazl »

Purchased an RA+ used and havent been able to figure out which relay box I've got (have two but they appear to be the same). From searches, analog had a sticker on the bottom; mine have no sticker but it's possible they did at one time. Is there any other way to know without breaking open the relay box? I unscrewed the main power and could see a pair of jumpers at the far end near the USB connector. The jumper looked to be on the pins nearest the USB connector; does this provide anything useful?

If I do end up opening the box, what is the best method of doing so without destroying it?

That sounds like PWM. If you do open the box, be aware that the label on the jumpers is reversed (PWM/Analog). IIRC, all you have to do is remove the screws on the top and then pry to get it to come apart.

If it's a PWM box there is no way to change it to analog (unless the analog components were installed originally), correct?

Just move those 2 jumpers to the other side.
The label is inverted.
It shows Analog/PWM, but it is in fact PWM/Analog

So do the PWM only boxes not have the jumpers?

They do.
They are set just like in the photo.
That's why your box is currently PWM and not analog.

So there is no difference in the relay boxes? I thought there were versions of the box that didnt have the capability to do analog.

That's I mentioned above.
Just move the jumpers to turn your box into an analog version.
Older version didn't have the capability. Luckily, yours can :)
