incremental encoders
Information
Using a HT6 adapter for level conversion from HTL signals to TTL signals, it is also possible to
connect a differential HTL incremental encoder to terminal X4. Note that, with an external power
supply, the maximum level of 20 V
DC
for the the HTL signals may not be exceeded.
