Technical Manual 1.02, C350 Professional
Analog I/O
The C350 pro unit has four analog inputs and four analog outputs. Both the inputs and the
outputs have a resolution of 10bit and can individually be configured to either voltage or
current input/output.
Analog inputs
As mentioned the analog inputs can individually be configured to work either as voltage or
current measurements inputs. The range in voltage mode is 0-10VDC and in current mode
it is 0-20mA. The resolution of the analog-to-digital converter is 10bit or 1024 in decimal
scale. The decimal value with 10V/20mA applied to the input is 1023 and 512 for
5V/10mA.
As default the inputs are configured as voltage inputs. For placement and configuration of
the hardware jumpers inside the unit, please refer to the unit configuration guide in
Appendix A.
The input signal is connected between AINx and AGND. AGND must be connected to the
reference of the connected equipment. Please be aware that deviations may occur, as the
system is very noise sensitive. Avoid long unshielded wires and large fast-changing
signals routed parallel to the analog signals. The impedance of the analog inputs is 40kΩ.
Each input is low-pass filtered, ESD and transient protected.
