Output Card 2000-Out - Nokeval 2012 User Manual

OUTPUT CARD 2000-OUT

Connections
The analog output card
6 V
provides one mA or V output
signal. These can not b used at
5 Com
the same time.
4 mA
The analog output card can be
3
installed in slots B or C or both.
2
An active mA output is provided
1
in terminals 4+ and 5-. Voltage
output is in terminals 6+ and 5-.
Operation
The analog output is configured to follow any
of the channels:
• 1 = slot A input
• 2 = slot B input
• 7 = math channel

The reading of the selected channel is
calculated to milliamps or volts using two
freely configurable scaling points.
If the channel is indicating fault (the input
signal is below MeaMin), the analog output is
steered to exceed the range by 20% or its
electrical maximum 22mA or 11V.

Out/Rdg and Out
The scaling of the output. When the reading
corresponds to Rdg1, the analog output will
be Out1 mA or V. Likewise, when the
reading corresponds to Rdg2, the output will
be Out2. Between and outside these points,
linear interpolation is used.
