Hi there, I am very new to the electronic stuff. We have an industrial equipment that is controlled by a 24 V in/out PLC ( fec-fc30-fst). I recently bough a Wantai DQ542MA driver and a 42byghm810 Stepper that i want to connect to the whole thing in order to automate a certain process. My question is very simple. The control of the DQ542MA is rated at 5V, but my intention is to connect it to an output from the PLC which is 24v. How can i easly lower the voltage? Voltage divider with resistors? or the fact that the DQ542MA I/O is opto-isolated means that i should not care and passing 24V to it is ok? Thank you
no the Opto couples will not save you . you best bet is to drop the voltage directly. now if you can find an external optocouple that accept Hi to lo signals your ok. But a Voltage divider will work. shield the **** out of everything.
