Expansion Boards
Do not use digital output modules on I/O Expansion Board B for control
applications.
False triggers may result when supply power to the board is lost.
Contact Siemens Energy & Automation Customer Service at 800-427-2256
for assistance if you want to use digital output modules on I/O Expansion
Board B for control purposes.
The external input and output capabilities of the 9700 Power Meter can be
expanded using up to two plug-in I/O expansion board s. Each expansion
board can provide multiple analog inputs, analog outputs, digital inputs,
and/or digital outputs. A list of the I/O devices supported by the 9700 Power
Meter is available in Appendix A under the section “Ordering Options”.
The functions of the I/O devices are controlled by Analog Input, Analog
Output, Digital Input, Digital Output, and Pulser modules. Input and Output
modules are configured by specifying the port they use to send or receive
signals (see page 4–20), and configuring other settings specific to the type
of operation they perform.
Each expansion board offers 15 slots you can plug I/O devices into. Slots 0
through 7 support digital input, digital output and analog output devices
only (analog input devices are not supported). Slots 8 through 14 support
digital input, digital output, analog input and analog output devices. Slot 15
is not supported. Other restrictions apply to the use of analog I/O devices,
as discussed below.

Slots are numbered on the
expansion boards. Note that
slots 0–7 do not support
analog input devices, and
slot 15 is not used. Slots 0 through 7
support DI, DO and AO
Slots 8 through 14
support DI, DO, AI and AO
Devices in slots 0 through 7
must be ALL INPUTS or ALL
OUTPUTS
(do not mix inputs and outputs)
