1397 I/O Expansion Card
1397 – 5.19 August, 2000
Analog Output Settings
The I/O Expansion Card supports two analog outputs — Anlg Out 3
and Anlg Out 4. Both I/O Expansion Card outputs are unfiltered,
where as standard analog outputs are averaged.
Anlg Out 3 has (2) parameter settings
1
and can be jumpered to supply
(2) types of output signals.
Anlg Out 4 has (2) parameter settings
1
and can only supply a bipolar
DC voltage.
Analog outputs can be scaled to supply DC voltage signals as low as
5V DC, but the maximum resolution of 0.025% is only obtained when
a full scale output signal is used. Analog outputs are updated every
20mS.
