The spec's shown is a general sheet covering all options, you would need to know the actual details of the one you have, i.e. supply voltage, type of output (TTL, RS485 etc). pulse count, this appears a different one than you original post?
This model comes in several versions.

That looks like a data sheet covering a range of encoders. For example it covers encoders with between 100 and 5000 pulses per revolution. A particular example of the encoder can only have one value for pulses per revolution. The output frequency will be (PPR value) x (RPM/60) Hz
If you look at page 2 of the data sheet you will be able to work out which variant you have from the FULL PART NUMBER.

If using in a noisy or lengthy cable run environment, I would suggest using the RS485, but you would need a RS485 receiver IC on the pic end.
I seem to recall you are using it on the conveyor distance application, depending where the encoder is mounted, (pulses per distance). I would not think you need a very high resolution.

You will need to translate the push-pull 8-30vdc supply to the 5v required at the pic.
Plus you would only need one channel A-B etc.
It is the highest resolution avail, 5k pulses/rev, a lower resolution would have been ample.

I am using 4N25 Opto to convert 24V DC to 5V DC

I have the same connection with encoder



Do I need pull up/ Pull down resistor for PIC16F877A?

What I think that I am seeing is that there is a choice of ordering it set up for one of three ranges. So at that point you need to examine the label on the device to see which it uses. Or you can see if it works with a 5 volt supply, and if it does then you are all set.
The pulse frequency will depend on the speed of rotation and the pulses per revolution. The values in the data sheet are the maximum possible frequency.
