• 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 by configuring jumpers on the STP268-EC. Refer to
Chapter 3 starting on page 37 for more information on configuring these jumpers.
• Install jumper W3 on the 5B Series backplane to connect Amp Low to Analog Ground on
the backplane.
• 5B and 7B Series thermocouple modules provide their own CJC and return a voltage that
already compensates for CJC. Therefore, when using 5B or 7B Series modules, you do not
have to compensate for offsets.
• The output of many 5B modules is ±5 V. The output of many 7B modules is 0 to 10 V.
Ensure that you select an input range that matches the output of the 5B or 7B modules that
you are using. For example, if you are using 5B modules that have an output of ±5 V, use a
bipolar input range and a gain of 2 on the DT9800-EC Series function module.
• Connect all unused inputs to analog common. Reading an open channel can cause settling
problems on the next valid channel.
Refer to the data sheets and user’s manuals for the 5B and 7B Series for detailed information
on using the backplanes and modules, including how to configure jumpers on the backplane,
install modules, wire signals to the modules, and connect power to the backplanes.
