I assume you're not using the line driver version, because the manual says it outputs 5VDC.

I would try removing the transistors and putting in resistors in series. Or try using a larger value resistor in series with the base of your transistors. It could be it's too low.

I'm using a 4k7 resistor for the base. the signal from the encoder is either 0 or 24 and the switching time should be extremely high (I assume since the encoders allow up to 5000 rpm) to affect here.

This is way too low. Try a 100k resistor. I think it's picking up noise and amplifying it.

I'll try and let U know.

My apologies for not getting back to you guys with this.
Due to work priorities I had to postpone this project and I haven't been able to test changing resistors yet.
As soon as I'm able to test this I'll let everybody know whether it works or not.
Thanks to all for your help
