Fast Analog Input Module 7
Set the Simulation Jumper The module is shipped with the simulation jumper set in position POS G. This
setting allows input data to go above and below the range points. If the
simulation jumper is set to the POS E position, input data is clamped (does
not exceed) at range end points.
Set the Configuration
Jumpers The module has configuration jumpers for determining the input type (voltage
or current) desired for each input. The module is shipped with the
configuration jumpers positioned for voltage mode.
Not that you can select either voltage or current for each input, but they must
all be either single-ended or all differential. Do not mix single-ended or
differential inputs on the module.
POS G POS E
Simulation Jumper (shown in POS E
position). This position provides Clamped
Input Data at range end points.
Top edge of circuit board
1. Locate the simulation jumper at the top edge
of the module circuit board.
2. Using your fingers, slide the jumper of f the 2 posts.
3. Carefully position the jumper on 2 of the 3 posts that
correspond to your requirement.
