Wiring for digital input terminals:
Generally, shield cable is adopted and wiring distance should be as short as possible. When active
signal is adopted, it is necessary to take filter measures to prevent power supply interference. Mode of
contact control is recommended.
Digital input terminals are only connected by source electrode (NPN mode) or by drain electrode (PNP
mode). If NPN mode is adopted, please turn the toggle switch to the end of “NPN”.
Wiring for control terminals as follows:
1. Wiring for positive source electrode (NPN mode).
