6.4.7 Analog control inputs
The PCIO2001-A1 provides one connector ('X9') with 8 analog control inputs.
The analog control inputs are used as a local gain control or as a control for audio
output volume.
The analog control inputs can be configured as supervised inputs or configured to
be used to supervise outputs.

6.4.7.1 Use analog control inputs
For regular use of analog control inputs, see Use analog control inputs [➙ 56].
Analog control inputs used as supervised inputs
The analog control inputs can be configured as supervised input with setting the
jumper 1 of the ID-Switch. See Configuration with the ID-Switch [➙ 77].
The inputs are used to supervise the wiring of an external potential free contact.
The wiring is supervised for open circuit and short circuit. The analog control inputs
are displayed in the configuration tool as digital inputs 1-8.
