If the multi-function input terminal is set as the sink logic, the
PSC terminal acts as an external power supply input terminal.
If the multi-function input terminal is set as the source logic,
the PSC terminal acts as an internal power supply output
terminal.

supply output • External voltage directive is 0 to 9.8 V. (Nominal input: 10 V)
Note: When the multi-function input terminal has no allocation
of [16: AT], the frequency of total voltage and current
directive values will be output. When selecting and
using either the voltage or current, be sure to allocate
[16: AT] to the multi-function input terminal.
