…Input/Output
Analog Outputs
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.
Analog Output 1 (4)
Note
. CM30 / 50:
Analog Output 2
available only if an option board is fitted –
see pages 16 (CM30) and 17 (CM50) for option board details.
CMF310:
Analog Outputs 3 / 4
available only if an optional
Output / Slope
Relays
board is fitted – see page 20.
Output Type
Selects the output type required (applicable only to Analog Output 1).
S
ource
Selects the parameter to be assigned to the output – see Appendix A, page 104 for
description of sources.
Elect. Low*
The current output required when the source value is equal to the
Eng Low
value –
see page 43.
Elect. High*
The current output required when the source value is equal to the
Eng High
value –
see page 43.
Auto Eng Range*
If enabled (
On
) the
Eng High
and
Eng Low
values for the output are set automatically
to the engineering range values of the source.
Eng Low*
The minimum engineering range output value.
Eng High*
The maximum engineering range output value.
Polarity**
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.
