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 14.
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 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.

* The power rating of the dry contact module must not exceed 10 VA under steady state or momentary in-rush conditions. For volt-
ages at or below 20 volts, the current limit is 0.5 amps. For voltages above 20 volts, the maximum allowable current is determined
by the following equation: 10 VA / Voltage = Current maximum. Rating curve is in the data sheet.

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.
