These resistor locations connect the high side to the low side of the
corresponding channels, thereby acting as shunts. If, for example,
you add a 250
Ω
resistor to location R17, and connect a 4 to 20 mA
current loop input to channel 0, the input range is converted to 1 to
5 V. Note that, depending on your application, you may need to use
resistors R1 to R16 with resistors R17 to R32 for proper operation.
Refer to
page 74 for an example of using current shunt resistors.
Configuring the STP268-EC Screw Terminal Panel
This section describes how to configure an STP268-EC screw terminal
panel for use with analog output modules on the 5B01 and 7BP16-1
signal conditioning backplanes.
Note: You cannot use analog output modules on the 5B08, 7BP04-1,
or 7BP08-1 backplane.
By default, the 5B01 and 7BP16-1 backplanes map to single-ended
analog input channels 0 to 15. However, you can use channels 14 and
15 on the 5B01 or 7BP16-1 backplane as analog output channels 0 and
1.
You can determine how channels 14 and 15 are used on the 5B01 and
7BP16-1 backplanes using jumpers on the STP268-EC screw terminal
panel.
To use channels 14 and 15 on the 5B01 or 7BP16 backplane as analog
inputs, remove jumpers W1 through W4 on the STP268-EC screw
terminal panel.
To use channel 14 on the 5B01 or 7BP16 backplane as analog output
channel 0, install jumper W1 (DAC0 Ground) and W2 (DAC0) on the
STP268-EC screw terminal panel.
