SNAP Analog Input Modules
Description
Part Number
SNAP I/O analog input modules are part of
Opto 22’s SNAP PAC System. All of these
modules mount on a SNAP PAC rack with a
SNAP PAC brain or R-series controller, either

A minimum number of SNAP module types
support a full range of analog input
requirements. These software-configurable
modules handle a wide variety of signal
levels. They provide high resolution (0.004%
of nominal range) for precise signal levels, as
well as multiple-channel packaging. All
SNAP analog modules are factory calibrated
and individually tested. Part numbers

SNAP analog input modules have an on-
board microprocessor to provide module-
level intelligence, which makes them an
ideal choice for Original Equipment
Manufacturers (OEMs). For additional
information about the standalone operation
of SNAP analog modules, see Opto 22 form

Notes for legacy hardware: Some of these
modules also work with older Opto 22 I/O
processors (brains or on-the-rack
controllers) and M-series or B-series racks. To
check processor compatibility, see the table
on page 3.
