SNAP PAC System
Designed to simplify the typically complex
process of selecting and applying an
automation system, the SNAP PAC
System consists of four integrated
components:
SNAP PAC controllers
PAC Proje c t
SNAP PAC brains
SNAP I/O
SNAP PAC Controllers
Programmable automation controllers
(PACs) are multifunctional, modular controllers based on open
standards.
Opto 22 has been manufacturing PACs for over two decades. The
standalone SNAP PAC S-series, the rack-mounted SNAP PAC Rseries, and the software-based SoftPAC™ all handle a wide range
of digital, analog, and serial functions for data collection, remote
monitoring, process control, and discrete and hybrid
manufacturing.
SNAP PACs are based on open Ethernet and Internet Protocol (IP)
standards, so you can build or extend a system easily, without the
expense and limitations of proprietary networks and protocols.
Wired+Wireless™ models are also available.
PAC Project S o f t ware Su ite
Opto 22’s PAC Project Software Suite provides full-featured, costeffective control programming, HMI (human machine interface)
development and runtime, OPC server, and database connectivity
software for your SNAP PAC System.
Control programming includes both easy-to-learn flowcharts and
optional scripting. Commands are in plain English; variables and I/
O point names are fully descriptive.
PAC Project Basic offers control and HMI tools and is free for
download on our website, PAC Project

essional, available for separate purchase, adds one SoftPAC,

OptoOPCServer, OptoDataLink, options for controller redundancy
or segmented networking, and support for legacy Opto 22 serial
mistic™ I/O units.
SNAP PAC Brains
While SNAP PAC controllers provide central control and data
distribution, SNAP PAC brains provide distributed intelligence for
I/O processing and communications. Brains offer analog, digital,
and serial functions, including thermocouple linearization; PID
loop control; and optional high-speed digital counting (up to 20
kHz), quadrature counting, TPO, and pulse generation and
measurement.
SNAP I/O
I/O provides the local connection to sensors and equipment.
Opto 22 SNAP I/O offers 1 to 32 points of reliable I/O per module,
depending on the type of module and your
needs. Analog, digital, and serial modules are
all mixed on the same mounting rack and
controlled by the same processor (SNAP PAC
brain or rack-mounted controller).
Quality
Founded in 1974, Opto 22 has established a
worldwide reputation for high-quality products.
All are made in the U.S.A. at our manufacturing
facility in Temecula, California. Because we
test each product twice before it leaves our
factory, rather than only testing a sample
of each batch, we can guarantee most
solid-state relays and optically isolated I/O
modules for life.
