Using the Onboard Digital Inputs
The 9330 and the 9350 meters’ four onboard digital (status) inputs can be used for
monitoring external contacts or pulse counting applications. These inputs can be
used for dry contact sensing, but they cannot be used for voltage sensing
applications.
monitoring external contacts or pulse counting applications. These inputs can be
used for dry contact sensing, but they cannot be used for voltage sensing
applications.
The function of each digital input is controlled by the Digital Input modules S1
through S4. These modules are preconfigured at the factory, together with four
Counter modules for counting status changes, and an External Pulse module for
resetting the Counter modules.

The four Digital Input modules are factory configured as follows (refer to the

Once you have connected the status inputs to the field equipment they are going
to monitor, check the meter’s Digital Input modules to ensure they are configured
appropriately.

Using the Optional Analog Inputs
The four optional Analog Input ports allow you to monitor a wide range of
conditions, such as device cycles (RPM), flow rates, fuel levels, oil pressures and
transformer temperatures. Both types of Analog Inputs (either 0-20mA or 0-1mA)
are suitable for monitoring DC signals from transducers in your system. Analog
Input modules control the analog input ports.

You use Designer to create and configure Analog Input modules. Set the Analog
Input module’s Port setup register to the appropriate analog input port on the rear
of the meter. Link the Analog Input module’s ScaledValu output to another module
or framework for analysis.
