The analog outputs can be configured to retransmit any analog value and have a
configurable range from 0 to 24 mA. Output 1 can also be configured to function as a
digital output.
Note. Analog Output 2 is available only if an option board is fitted – see pages 12
(CM30) and 13 (CM50) for option board details.
Selects the output type required (applicable only to Analog Output 1).
Selects the parameter to be assigned to the output – see Appendix A, page 79 for
description of sources.
The current output required when the source value is equal to the Eng Low value – see
page 33.
The current output required when the source value is equal to the Eng High value – see
page 33.
If enabled (On) the Eng High and Eng Low values for the output are set automatically to
the engineering range values of the source.
The minimum engineering range output value.
The maximum engineering range output value.
Sets the polarity of the output signal.
If set to Negative, the output is energized when source is inactive.
If set to Positive, the output is energized when source is active.
