Appendix A: AIO Option
The AIO Option is an Analog Output, providing 12 analog interface outputs driven
from a single, multiplexed, 16-bit digital-to-analog converter. This sub-system is
controlled by a single Motorola DSP56001 24-bit processor, which is interfaced to
the central processor via an internal high speed RS485 data link. Refer to Figure 8,
Rear Panel Partial View.
The Analog Output and the Digital I/O connectors supports the AIO option when
fitted. You can request this option to be fitted with your Phase Angle Voltmeter.
AIO Option Features
This option’s key features include:
•
Each analog output is individually setable for
±
5V or
±
5mA output span with
0.05% basic accuracy.
•
Each analog output may be set to output any parameter or parametric deviation,
with user defined offset, span, and filtering.
AIO Option Commands
Analog Command
Analog Command Action
ANALOG[n]=DEFAULT
To return the analog output (n) to the
parameter’s zero offset and span as specified via
the front panel control, using command string.
ANALOG[n]=parameter
To set the output level to one determined from
the value of the passed parameter.
ANALOG[n]=range/zero/span
To configure the analog output (n) to the
indicated range of 5V, 10V, or 5mA, and the
numeric value for the parameter’s zero offset
and span.
