ANALOG CONTROL IN
The upper half of the control port has eight freely programmable control inputs for voltages of
between 0 volts and 10 volts. The inputs are numbered 1 through 8. The controller provides
its own voltage supply for externally connected control elements, e.g., a potentiometer. The
voltage supply is available at the control port connections for 10V REF and ground; see the
following diagram.
Figure 6.10: Sample application of a control input and use of an analog input signal
The control inputs can also be used as digital control inputs. Internally, the control inputs are
connected to ground via a resistor. If an input is connected to the 10 V REF pin or another,
external voltage, the input switches to the active status (On).
Caution!
The maximum permissible voltage on a control input is 32 V.
