General
All connections except RS232 are available on screw terminals. The opto-
isolated inputs require a voltage between 4.5v and 24v DC for a positive logic
level. Open circuit or less than 1v gives a negative logic level.
The case of the PP600 is not connected to the GND
supply connection. On previous revisions of this
product the case was connected to GND.
The input connector has connections as follows:
