Hi,

     I am using SM43JR20 but I couldn't find any information about the type of encoder signals that is safe to be connected to the PLC.

If possible can you suggest some shaft encoders that can be connected to this PLC model?

 

Thanks in advance

I typically use a quadrature encoder (has two outputs - A and B ) with a sourcing 24V signal.  These are available from many manufacturers.  Do you have a specific one you're looking at?

Broadcom Incremental Encoder 256 ppr 12000rpm 4.5 → 5.5 V dc is the one I am looking at. I have a 5 V source with me. Will it work ?

No. 

The PLC IO module needs 24V for the "1" state.  You'll need a high speed converter to step the voltage up.

Try using Dr. Google to find something, or I've been known to roll my own on a small piece of perf board-

The output will be inverted, but that doesn't matter for counting pulses.
