SNAP Isolated Analog Input
Modules
Description
SNAP I/O isolated analog input modules provide two channels
isolated from each other, thereby eliminating problems caused by
ground loop currents. These isolated analog modules are part of
Opto 22’s SNAP PAC System and mount on SNAP PAC racks with an
I/O processor (brain or on-the-rack controller).
Since many SNAP analog input modules are software-configurable
and handle a wide variety of signal levels, a small number of
modules can support a full range of analog input requirements.
Modules provide high resolution for precise signal levels, as well as
dual-channel packaging. All SNAP analog modules are factory
calibrated. Part numbers ending in -FM are Factory Mutual
approved. Dimensional drawings are on pages 11–14.
SNAP analog input modules have an on-board microprocessor to
provide module-level intelligence, making them an ideal choice for
Original Equipment Manufacturers (OEMs). For more information
about the standalone operation of SNAP analog modules, see the
SNAP I/O Module Integration Guide (Opto 22 form #876).
Notes for legacy hardware: These modules can also be used
with SNAP Simple, SNAP Ethernet, and SNAP Ultimate brains, as
well as SNAP mistic brains such as the serial B3000. These modules
can be installed on M-series or B-series mounting racks.
Isolation
All SNAP analog input modules are transformer isolated as well as
optically isolated from all other modules and from the SNAP brain
or on-the-rack controller. In addition, the modules described in this
data sheet feature two channels isolated from each other.
Transformer isolation prevents ground loop currents from flowing
between field devices and causing noise that produces erroneous
readings. Ground loop currents are caused when two grounded
field devices share a connection, and the ground potential at each
device is different. Optical isolation provides 4,000 volts of transient

(4,000 V for 1 ms) protection for sensitive control electronics from
industrial field signals.
Channel-to-channel isolation gives you complete freedom from
ground-loop problems even on grounded devices connected to
channels on the same module.
