Do not use digital output
modules on I/O Expansion
Board 'B' for control
applications, as false
triggers may result when
the supply power to I/O
Board 'B' is interrupted.

Expansion Board I/O Device Restrictions
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 0 through 7
support DI, DO and AO
Devices in slots 0 through 7 must
be ALL INPUTS or ALL OUTPUTS
(do not mix inputs and outputs)
Analog Device Restrictions — Power Supplies
The allowable number of analog devices the 9700 Power Meter can support
increases significantly when two external power supplies are used to power
the expansion boards. The default configuration of Expansion Board A does
not include a power supply; it has to be purchased separately. If Expansion
Board A is powered directly from the 9700 Power Meter, then a maximum of
six analog devices can be installed on it. (A separate power supply is
required for Expansion Board B in any configuration.)
To use the maximum number of analog I/O devices, two power supplies
must be used (one for each expansion board). Note that if a separate power
supply is used with Expansion Board A, then the jumper (JMPR) must be
removed from the board. Failure to remove the jumper will void the 9700
Power Meter's warranty.
Analog Device Restrictions — Direction (Input or Output)
The direction of all of the devices in slots 0 through 7 and slots 8 through 14
must be the same. You cannot mix inputs and outputs within these two
groups of slots; however, you can have all inputs in slots 0 through 7, and
all outputs in slots 8 through 14 (or vice versa).
Slots 8 through 14 support
DI, DO, AI and AO
Devices in slots 8 through 14
must be ALL INPUTS or ALL
OUTPUTS
(do not mix inputs and outputs)
