Features
4,000 Vrms optical isolation
Built-in LED status indicators
4 times encoder resolution
Input signals in 4–24 VDC range
Description
The SNAP-IDC5Q quadrature input module is part of the SNAP
PAC System. It mounts on a SNAP PAC rack and is designed to
allow a SNAP PAC brain or R-series controller with high-speed
counting capability (either a standard wired model or a
Wired+Wireless™ model) to resolve two axes of rotating
position information from quadrature encoder devices. The
module outputs a pulse to the SNAP PAC processor upon each
change in quadrature state. The processor counts the module
output pulses and keeps track of the direction and position.
The SNAP-IDC5Q can be used with most quadrature devices,
including transducers with TTL, CMOS, and open collector
outputs. All inputs are isolated from each other and do not
share any common connections.
SNAP racks have a retention rail locking system. Use two 4-40
by ½-inch standard machine screws to hold each module
securely in position on the SNAP rack.
Module Operation
For each axis, the SNAP-IDC5Q quadrature module converts a
quadrature signal to a stream of pulses that is sent to the I/O
processor on one of two input channels. The rotation direction
of the encoder determines which output is used.
The position count is incremented when the signal into the A
channel leads the signal into the B channel. It is decremented
when the signal into the B channel leads the signal into the A
channel.
Since the I/O processor (brain or on-the-rack controller) has a
maximum input count rate, the maximum allowable RPM at
which the encoder may turn is related to the number of cycles
per turn that the encoder outputs. See charts on the next two
pages.
Notes for legacy hardware: The SNAP-IDC5Q is also
compatible with Ethernet-based SNAP-B3000-ENET and
SNAP-UP1-ADS brains, as well as B3000, B3000-B, and B3000-
HA brains, which use the mistic protocol. From a mounting
standpoint the module is treated as a standard SNAP I/O
digital module, which means it can be installed only in the first
eight positions (0–7) of larger SNAP B-series racks.

Products
Opto 22 develops and manufactures reliable, easy-to-use, open
standards-based hardware and software products deployed
worldwide.
Industrial automation, process control, building automation,
industrial refrigeration, remote monitoring, data acquisition,
Industrial Internet of Things (IIoT), and information technology
applications all rely on Opto 22.

SNAP PAC System
Developer- and IIoT-ready, the SNAP PAC System connects
physical assets to databases and applications using open
standards. 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
SNAP PAC programmable
automation controllers handle a
wide range of digital, analog, and
serial functions for data collection,
remote monitoring, process control,
and discrete and hybrid manufacturing.
For IIoT applications and easier integration with company
systems, standalone and rack-mounted SNAP PACs include a
built-in HTTP/HTTPS server and
RESTful API
(application
program interface). The REST API gives you secure, direct access
to I/O and variable data using your choice of programming
languages. No middleware, protocol converters, drivers, or
gateways needed.
Based on open Ethernet and Internet Protocol (IP) standards,
SNAP PACs make it easier to 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 offers full-featured, cost-
effective control programming, HMI (human machine interface),
OPC server, and database connectivity software.
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
software-based controller, 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, local
PID loop control, watchdog, totalizing, and much more.
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.
Analog, digital, and serial modules are mixed on one mounting
rack and controlled by a SNAP PAC brain or rack-mounted PAC.
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 from engineers with 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 user’s guides, and OptoForums.
In addition, hands-on training is available for free at our Temecula,
California headquarters, and you can
register online
.
Purchasing Opto 22 Products
Opto 22 products are sold directly and through a worldwide
network of distributors, partners, and system integrators.
