IMPORTANT SAFETY CONSIDERATIONS
It is very important for the user to consider the possible adverse
effects of power, wiring, component, sensor, or software failures in
designing any type of control or monitoring system. This is
especially important where economic property loss or human life is
involved. It is important that the user employ satisfactory overall
system design. It is agreed between the Buyer and Acromag, that
this is the Buyer's responsibility.
1.0 GENERAL INFORMATION
The Industrial I/O Pack (IP) Series IP320 module is a 12-bit,
high-density, single-size IP analog input board with the capability to
monitor 20 differential or 40 single-ended analog input channels.
The IP320 utilizes state of the art Surface Mounted Technology
(SMT) to achieve its high channel density. It offers a variety of
features which make it an ideal choice for many industrial and
scientific applications as described below.

KEY ANALOG INPUT FEATURES
•
High Channel Count - Monitors up to 20 differential, or 40
single-ended analog inputs (acquisition mode and channels are
selected via a programmable control register). Up to four units
may be mounted on a carrier board providing up to 80
differential inputs, or 160 single-ended inputs in a single
system slot.
•
12-bit Accuracy - Contains an enhanced, 12-bit, successive
approximation Analog to Digital Converter (ADC) with an 8.5uS
conversion time.
•
High Speed - A maximum system throughput rate of 100K
samples per second can be obtained using the pipelined mode
of operation.
•
Multiple Input Range - Three hardware jumper-selectable
ranges capture both bipolar and unipolar voltage inputs:
-5 to +5V, -10 to +10V, and 0 to +10V.
•
Programmable Gain - Gains of 1, 2, 4, and 8 are
programmable via the control register.
•
Software/Hardware Trigger - Input acquisition can be
triggered via software, or by an external hardware input for
synchronization to external events.
•
Precision References - On-board, high-precision voltage
references provide the means for accurate and reliable
software calibration of the module.
