Module Group Description
Periodic Timer Provides a running timer that pulses at programmable intervals.
When used in conjunction with other modules, the Periodic Timer
can trigger events on a regular basis; for example, when used with
a Recorder module, the Periodic Timer can trigger entries for a
snapshot log.
Power Meter Performs calculations on sample waveforms of a three-phase or
single-phase power system. The Power Meter module is
automatically linked to the Data Acquisition module, and together
these modules serve as the link between all other modules and the
physical world.
Pulser Sends pulses or state changes (KYZ mo de) to the specified
hardware port.
Sliding Window
Demand Calculates sliding window and predicted demand. Useful f or
providing average power consumption over a spec if ied time
interval.
Thermal Demand Calculates thermal demand to pro vide average power consumption
over a specified time period. Provides a contemporary alternative to
thermal averaging (the traditional demand indicator in wh ic h an
element is heated in a watt-hour meter).
Using Onboard and Expansion I/O
The 9700 Power Meter is available with numerous I/O options. The standard
configuration includes eight onboard status inputs. Four onboard analog
inputs and two expansion boards, each with up to 15 I/O modules, are
available as ordering options.

Onboard Status Inputs

The eight onboard status inputs can be used for monitoring external
contacts or pulse counting applications. These inputs use a current sensing
technique to monitor contact status by providing an internal 30 VDC supply
for self-excitation. These inputs can be used for dry contact sensing, but
not for voltage sensing.
The function of each status input is controlled by the Digital Input modules
1 through 8. These modules are preconfigured at the factory, together with
eight Counter modules for counting status changes, and an External Pulse
module for resetting the Counter modules.
