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 0-20mA. The resolution of the digital-
to-analog converter is 12bit or 4096 in decimal scale.
As default the outputs are configured as voltage outputs. For placement and configuration of the
hardware jumpers inside the device, please refer to the device configuration guide in Appendix A.
The default resolution is 10 bits (0.1023). The application can change the resolution to the full 12 bit
(0..4095). Please consult the RTCU IDE for further details.
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 are only valid if the load is maximum 250Ω.
Each output is ESD and transient protected.
Please note: The RTCU NX-900 device must be supplied with minimum 15 VDC or AC in order for
the analog outputs to work according to specifications.
