Universal Analog Inputs
Note: See the data sheet for the XLe/XLt model you are using for jumper settings and CHAPTER 14 for
details on how to use Cscape to configure the digital filtering.
The universal analog inputs provide a high resolution, very flexible interface for a variety of analog inputs.
These inputs include voltage, current, thermocouple, RTD and millivolt. Each channel can be configured
separately using jumpers and configuration settings in Cscape.
Like the standard analog inputs, these inputs have a digital filter that can be used to filter electrical noise
that may be unavoidable in some installations. The downside to digital filtering is the inputs will respond
more slowly to sudden changes in the actual input.

Analog Outputs
Note: See CHAPTER 10 for high speed I/O information and refer to the datasheet for XLe/XLt model you
are using for details on jumper settings.
The analog outputs on XLe/XLt devices provide high resolution voltage or current outputs. The voltage or
current selection is controlled with jumpers and configuration settings in Cscape. Note that each channel
can be separately configured for voltage or current mode.
When the controller is stopped the operation of each output is configurable. The outputs can hold the
state they were in before the controller stopped or they can go to a predetermined value. By default
analog outputs are set to a value of zero. For more information on Stop State, see CHAPTER 14 for the
configuration chapter for Cscape settings.
