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 22 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).
SNAP-IAC5MA and SNAP-IDC5MA feature
manual-on/manual-off/automatic
switches, ideal for testing control
applications. The switches override input
from field devices, so you can 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.
Notes for legacy hardware: These modules can also be used
with SNAP Ultimate, SNAP Ethernet, and SNAP Simple brains,
and with other SNAP brains such as the serial B3000 and the
B3000HA. They also mount on B-series, M-series, and D-series
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 of the module during installation.

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 Project Software Suite
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 R-
series, 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 Software Suite
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
download on our website,
www.opto22.com
. PAC Project
Professional, 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.
Free Product Support
Opto 22’s California-based Product Support Group offers free,
comprehensive technical support for Opto 22 products. Our staff
of support engineers represents decades of training and
experience. Support is available in English and Spanish by phone
or email, Monday–Friday, 7 a.m. to 5 p.m. PST.
Additional support is always available on our website: how-to
videos, OptoKnowledgeBase, self-training guide, troubleshooting
and users guides, and OptoForums.
In addition, hands-on training is available for free at our Temecula,
California headquarters, and you can
register online
.
