Analog outputs
The analog outputs can individually be configured to work either as voltage or current
outputs. The range in voltage mode is 0-10VDC and in current mode it is 0-20mA. The
resolution of the digital-to-analog converter is 10bit or 1024 in decimal scale.
The decimal value for 10V/20mA output are 1023 and 512 for 5V/10mA.
As default the outputs are configured as voltage outputs. For placement and configuration
of the hardware jumpers inside the unit, please refer to the unit configuration guide in
Appendix A.
The output signal is connected to external equipment between AOUTx 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. In current mode the
specifications for the analog output only valid if the load is maximal 250
Ω .
Each output is ESD and transient protected.
Please note:
The C350 pro unit must be supplied with minimum 12VDC in order for the
analog outputs to work according to specifications.
