SNAP Digital Output Modules
Features
Four channels per module
Convenient pluggable wiring terminals; accepts up to
14 AWG wire
Powered by a single 5-volt supply
Channel-specific LEDs
Operating temperature: 0 to 70 °C
UL and CE approved (most modules); Factory Mutual
approved (part numbers ending in FM)
Description
Opto 22 SNAP I/O digital output
modules are part of the SNAP PAC
System.
Customers can choose from AC or DC
models. Optical isolation on all solid-
state modules provides 4,000 volts of
transient (4000 V for 1 ms) protection
for sensitive control electronics from
industrial field signals.
All SNAP digital modules have
removable top-mounted connectors
to provide easy access for field wiring.
All operate on 5 VDC control logic.
Each digital module features integral
channel-specific LEDs for convenient
troubleshooting and maintenance.
Each module is factory tested twice
before shipment, and most modules
are UL and CE approved. In addition,
part numbers ending in FM are
Factory Mutual approved.
SNAP output modules are used to
switch up to four separate AC or DC
loads. Output modules that are fused
use a standard fuse with a convenient
handle for easy replacement. DC
outputs are available in either a source
or sink configuration. AC outputs are
zero voltage turn on and zero current
turn off for transient-free switching.
The dry contact modules allow
switching of low power signals where
signal integrity must be maintained,
or where zero leakage current is a
requirement. Dry contact modules are

not solid-state devices. They use reed relays, which are
electromechanical devices. These modules do not provide
optical isolation. Current rating for dry contact modules
depends on the voltage they are used with, as shown in the
graph on page 16.
SNAP-OAC5MA and SNAP-ODC5MA are special modules
featuring manual-on/manual-off/automatic switches, ideal for
diagnostic testing of control applications. The switches
override output from the application, so you can quickly check
field device wiring. These modules each contain four isolated
channels.
The SNAP-OAC5-i, SNAP-ODC5-i, and SNAP-ODC5A-i modules
provide four isolated output channels.
For Ethernet-based applications requiring higher density of
digital I/O points, see Opto 22 form #1556, the SNAP High-
Density Digital Module Data Sheet.
I/O Processor Compatibility
SNAP digital output modules are compatible with all SNAP
PAC brains and rack-mounted controllers, including both
standard wired models and Wired+Wireless models.
Notes for legacy hardware: SNAP digital output modules
are also compatible with SNAP Ultimate, SNAP Ethernet, and
SNAP Simple brains, as well as other SNAP brains such as the
serial B3000 and the B3000HA. These modules can also be
used on B-series and
M-series mounting racks.
Installation
The following diagram shows part of a SNAP mounting rack.
The rack is shown without screw connectors.
Modules snap securely into place in the row of connectors on
the rack. Each module connector has a number. Digital output
modules and other types of SNAP I/O modules are mounted
on the module connectors starting at module position zero.
NOTE: Check the data sheet or user’s guide for the brain or on-
the-rack controller you are using to determine module
features available and any restrictions on module placement.
1. Place the rack so that the module connector numbers
are right-side up, with zero on the left, as shown in the
diagram above. (If your rack has screw connectors, the
screw connectors will be at the bottom.)
2. Position the module over the module connector,
aligning the small slot at the base of the module with
the retention bar on the rack. When positioning modules
next to each other, be sure to align the male and female
module keys at the tops of the modules before snapping
a module into position.
3. With the module correctly aligned, push on the module
to snap it into place.
4. (Optional) Use standard 4-40 x 1/2 truss-head Phillips
hold-down screws to secure both sides of each module.
CAUTION: Do not over-tighten screws.
5. Follow the wiring diagrams beginning on page 5 to
attach modules to the devices they monitor.
Modules require a special tool (provided) for removal.

Products
Opto 22 develops and manufactures reliable, flexible, easy-to-use
hardware and software products for industrial automation, remote
monitoring, and data acquisition applications.
SNAP PAC System
Designed to simplify the typically complex process of
understanding, selecting, buying, and applying an automation
system, the SNAP PAC System
consists of four integrated
components:
SNAP PAC controllers
PAC Project Software Suite
SNAP PAC brains
SNAP I/O
SNAP PAC Controllers
Programmable automation controllers
(PACs) are multifunctional, multidomain,
modular controllers based on open standards and
providing an integrated development environment.
Opto 22 has been manufacturing PACs for many years. The latest
models include 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 and are equally suited to 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 without the expense
and limitations of proprietary networks and protocols.
PAC Project Software Suite
Opto 22’s PAC Project Software Suite provides full-featured and
cost-effective control programming, HMI (human machine
interface) development and runtime, OPC server, and database
connectivity software to power your SNAP PAC System.
These fully integrated software applications share a single tagname
database, so the data points you configure in PAC Control are
immediately available for use in PAC Display, OptoOPCServer,
and OptoDataLink. 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, www.opto22.com. PAC Project
Professional, available for separate purchase, adds OptoOPCServer,
OptoDataLink, options for Ethernet link 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, serial, and special-purpose 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 and with over 85 million devices sold,
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.
Free Product Support
Opto 22’s Product Support Group offers free, comprehensive
technical support for Opto 22 products. Our staff of support
engineers represents decades of training and experience. Product
support is available in English and Spanish, by phone or email,
Monday through Friday, 7 a.m. to 5 p.m. PST.
Free Customer Training
Hands-on training classes for the SNAP PAC System are offered at
our headquarters in Temecula, California. Each student has his or
her own learning station; classes are limited to nine students.
Registration for the free training class is on a first-come, first-served
basis. See our website, www.opto22.com, for more information or
email training@opto22.com.
Purchasing Opto 22 Products
Opto 22 products are sold directly and through a worldwide
network of distributors, partners, and system integrators. For more
information, contact Opto 22 headquarters at 800-321-6786 or
951-695-3000, or visit our website at www.opto22.com.
