Two, 4, 8, or 32 single-ended inputs per module
Out-of-range indication
Factory calibrated; no user adjustment necessary
Description
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 standard wired model or a
Wired+Wireless
™
model.
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
ending in -FM are Factory Mutual approved.
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
#0876, SNAP I/O Module Integration Guide.
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.
Specifications begin on page 4. For
dimensional drawings, see pages 35–45.
IMPORTANT: Any system using analog
sensors and input modules should be
calibrated annually for analog signals. For
I/O units on a SNAP PAC System, use the PAC
Control
™
commands “Calculate and Set
Offset” and “Calculate and Set Gain.” For
other Ethernet-based I/O units, you can also
