SNAP Digital Input Modules
Features
Four channels per module
4,000-volt transient isolation
Convenient pluggable wiring terminals
Channel-specific LEDs
Operating temperature: 0 to 70 °C
UL and CE approved
Accepts up to 14 AWG wire
Factory Mutual approved (part numbers ending in FM)
Description
Opto 22 SNAP I/O digital input modules
are part of the SNAP PAC System. Optical
isolation on these modules provides
4,000 volts of transient (4000 V for 1 ms)
protection for sensitive control
electronics from industrial field signals.
Digital input modules can sense either
AC or DC signals.
All SNAP digital modules have
removable top-mounted connectors to
provide easy access for field wiring, and
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 and is UL
and CE approved. In addition, part
numbers ending in FM are Factory
Mutual approved.
SNAP input modules are used to sense
the on or off status for AC or DC voltages
from such sources as proximity switches,
push buttons, or auxiliary contacts. The
SNAP-IDC5G is ideal for detecting 48
VDC in telecom applications. The SNAP-
IDC5-HT is designed for sensors that
have a high leakage current.
The SNAP-IDC5-SW and SNAP-IDC5-
SW-NC modules supply power to an
external dry contact switch and sense
switch closure (SNAP-IDC5-SW) or
opening (SNAP-IDC5-SW-NC).

DATA SHEET
Form 773-090806
SNAP-IAC5MA and SNAP-IDC5MA are special modules featuring
manual-on/manual-off/automatic switches, ideal for diagnostic
testing of control applications. The switches override input from
field devices, so you can quickly determine whether a problem lies
in the application or in the device.
SNAP racks use a retention rail locking system that holds modules
securely to the rack. Normally, a hold-down screw is not required.
However, for applications that require additional module security,
each module has provisions for two 4-40 by ½-inch standard
machine screws to hold the module in position on the SNAP rack.
SNAP digital input modules are compatible with all SNAP PAC
brains and rack-mounted controllers, including Wired+Wireless™
models.
Notes for legacy hardware: SNAP digital input 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, M-series, and D-
series mounting racks.
Wiring Options
For easier, faster wiring of field devices to input modules, see the
SNAP TEX Cables and Breakout Boards Data Sheet, form #1756. Each
SNAP TEX cable snaps into the top of the module and terminates at
the breakout board with 18-gauge, color-coded flying leads,
already stripped and ready for wiring. Breakout boards offer
optional fusing, fuse-blown indicators, and bussed power to loads.

SNAP-IDC5-SW and SNAP-IDC5-SW-NC Modules
Description
The SNAP-IDC5-SW and SNAP-IDC5-SW-NC modules provide four
channels of contact status input. Each module supplies 15 volts of
power to an external dry contact switch. The SNAP-IDC5-SW senses
switch closure; the SNAP-IDC5-SW-NC senses switch opening. Each
user-supplied switch is connected with two wires. Because these
modules include power for the switch, they are particularly cost-
effective when labor costs for wiring external power are high.
Typical switches for use with these modules are switched status
sensors (level sensors, pressure indicators, etc.), magnetic reed
switches (used on doors or windows for burglar alarms), snap-
action micro switches, the auxilliary switches on motor starters, and
most relay contacts.
CAUTION: The SNAP-IDC5-SW and SNAP-IDC5-SW-NC inputs are
not intended to be used with contacts that are connected to any
external user-supplied voltage or currents.

pins; the module connector has 20 pins. The extra pins
on the mounting rack connector prevent misalignment

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
