Flat Pak I/O Modules
Description
Flat Pak I/O modules include AC and DC input and output
modules. All are industry-standard, plug-in modules with 4000
volts of optical isolation between the field side and the logic
side, and all are recognized by UL and CSA.
Because of their low profile, Flat Pak modules are ideal for
user-designed printed circuit boards where the standard
single-channel or Quad Pak modules do not provide an exact
fit.
AC/DC Input Modules
Flat Pak input modules handle either alternating current (AC)
or direct current (DC). These modules are used for sensing
ON/OFF voltage levels. All Flat Pak input modules are designed
with filtering on the input and a hysteresis amplifier for high
noise rejection and transient free “clean” switching. Each
module provides up to 4000 V of optical isolation between
field inputs and the logic side of the circuit.
Typical uses and applications include sensing the presence or
absence of voltage from sources such as:
Proximity switches
Limit switches
Selector switches
Push-button and toggle switches
Thermostats
Photoelectric switches
TTL-compatible devices
AC Output Module
The OAC5P Flat Pak output module is used for controlling or
switching AC loads. It is equivalent to a single-pole, singlethrow, normally open contact (FORM A, SPST-NO, Make). The
OAC5P features zero voltage turn-on and zero current turn-off.
Typical uses and applications for the OAC5P include switching
the following loads:
Relays
Solenoids and contactors
Motor starters
Heaters
Lamps or indicators
DC Output Module
The ODC5P Flat Pak output module is used for controlling or
switching DC loads. Typical uses and applications for the
ODC5P include switching the following loads:
DC relays
DC solenoids
DC motor starters
DC lamps or indicators

More About Opto 22
Products
Opto 22 develops and manufactures reliable, flexible, easy-touse hardware and software products for industrial automation,
energy management, remote monitoring, and data
acquisition applications.
OptoEMU Energy Management System
The easy-to-use OptoEMU Sensor monitors electrical energy
use in your facility and delivers detailed, real-time data you
can see and analyze. The Sensor can monitor energy data from
pulsing meters, electrical panels or subpanels, and equipment.
View energy data online using a software service or
incorporate the data into your control system for complete
energy management.
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 Proj e ct
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 and the rack-mounted
SNAP PAC R-series both 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.
PAC P roj e c t Softwa re Su i t e
Opto 22’s PAC Project Software Suite provides full-featured,
cost-effective 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

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 do
no statistical testing and each part is tested
twice before leaving our factory, we can
guarantee most solid-state relays and optically
isolated I/O modules for life.
