Analog Programming Inputs
The 44M04 mainframe has analog programming inputs. This feature allows an external
waveform to be tracked as long as it is within the load’s dynamic capabilities. The analog
programming inputs are available through a compression terminal block on the rear panel of
the 44M04 Mainframe. These inputs will accept a 0-10V signal. This signal is proportional to
the load module’s maximum current range.
Note:
The analog programming inputs will only operate with single channel load modules.
They
CANNOT
be used for dual channel load modules from the 42L series or the 42D5003.
Figure 3: Pin-out of Analog Pogramming Input Connector
The analog programming input operates in CC or CP modes only. The load module will
attempt to load proportionally according to the signal and the load module’s maximum current
or power range.
For example: 41L0660: Imax = 60A and Pmax = 300W
•
In CC mode, if the analog programming input is 5V = 30A load setting.
•
In CP mode, if the analog programming
input is 1V = 30W load setting.
The analog programming signal can act alone or it
can be summed with the programmed value set
via the front panel or the optional computer
interface (GPIB, RS232, USB, or LAN) or the
front panel.
Figure 4 shows the result of an analog
programming signal at 4Vac, 500Hz when it is
summed with a 24A programmed setting in CC
mode of 41L0660 load module.
