Description

SNAP I/O isolated analog input modules provide two or more

channels isolated from each other, thereby eliminating

problems caused by ground loop currents. These isolated

analog modules are part of Opto 22’s SNAP PAC System and

mount on SNAP PAC racks with an I/O processor (brain or on-

the-rack controller). SNAP isolated analog input modules are

compatible with all SNAP PAC brains and rack-mounted

controllers, including Wired+Wireless™.

Since many SNAP analog input modules are software-

configurable and handle a wide variety of signal levels, a small

number of modules can support a wide range of input

requirements. Modules provide high resolution for precise

signal levels, and all SNAP analog modules are factory

calibrated. Part numbers ending in -FM are Factory Mutual

approved. Dimensional drawings start on page 14.

SNAP analog input modules have an on-board microprocessor

to provide module-level intelligence, making them an ideal

choice for original equipment manufacturers (OEMs). For more

information about standalone SNAP analog modules, see the

SNAP I/O Module Integration Guide (form 876).

SNAP racks use a retention rail locking system that holds

modules in place. In addition, Opto 22 recommends using two

4-40 by ½-inch standard machine screws to secure each

module to the rack (recommended torque: 4 inch pounds

[0.45 Newton meters]).

Notes for legacy hardware: Most isolated analog input

modules can be used with SNAP Simple, SNAP Ethernet, SNAP

Ultimate, and SNAP mistic brains such as the serial B3000, and

with M-series or B-series mounting racks. For exceptions, see

individual module descriptions.

Isolation

All SNAP analog input modules are isolated from all other

modules and from the I/O processor. In addition, the modules

in this data sheet have all channels isolated from each other.

Channel-to-channel isolation gives you complete freedom

from ground-loop problems even on grounded devices

connected to channels on the same module.

Transformer isolation prevents ground loop currents from

flowing between field devices and causing noise that

produces erroneous readings. Ground loop currents are

caused when two grounded field devices share a connection,

and the ground potential at each device is different.

Isolation also provides protection for sensitive control

electronics from industrial field signals.

Description

The SNAP-AIARMS-i and SNAP-AIARMS-i-FM modules provide

an input range of 0 to 10 amps RMS AC/DC. An ideal input is the

5-amp secondary of a standard current transformer used to

monitor AC line current. These modules may also be used to

monitor AC current to greater than a 100-amp range, using a

current transformer of suitable ratio. The SNAP-AIARMS-i-FM

module is Factory Mutual approved.

The two channels are isolated from each other; they do not share

any field connection. These modules are ideal for differential

current measurements.

Description

The SNAP-AIMA-iSRC and SNAP-AIMA-iSRC-FM are similar to

the SNAP-AIMA-i module but include built-in loop sourcing

capability. With the connection of a single 24 V power

supply, these modules source 24 V for two 4–20 mA loops.

The loops are internally connected to the individual inputs.

The two channels and their loop sources are isolated from

each other; they do not share any field connection. In

addition, each loop source is current limited so that an

external fault on one loop will not affect the other.

The SNAP-AIMA-iSRC-FM is Factory Mutual approved.

Part Number Description

SNAP-AIRATE-HFi Isolated two- ch anne l anal og freq u ency i nput ,

2 Hz–500 kHz or 20 Hz–500 kHz

Isolated Frequency Input Module

Description

The SNAP-AIRATE-HFi module provides frequency to digital

conversion. Each channel can be configured for a 0.1-second

measurement interval, providing an input range of 20 Hz to

500 kHz, or a 1-second measurement interval, providing an

input range of 2 Hz to 500 kHz. Data freshness is dependent

upon and directly related to the measurement interval.

Nine volts through a 3.6 kOhm pull-up resistor is provided

internally for each channel for use with devices that have

open-collector outputs. This feature eliminates the need for

you to provide the pull-up voltage supply and associated

wiring, barrier strips, and so on. The module works with TTL,

CMOS, and open-collector outputs.

The two channels on the module are isolated from each

other. Since these channels do not share any common

connections, grounded sensors and field devices may be

used with them.

This module requires a SNAP PAC controller or brain with

SNAP PAC firmware version 9.3c or higher. It cannot be used

with legacy controllers or brains.

Products

Opto 22 develops and manufactures reliable, flexible, easy-to-use

hardware and software products for industrial automation,

energy management, remote monitoring, and data acquisition

applications.

groov

puts your system on your mobile device. With zero

programming, you can build mobile operator interfaces to

monitor and control systems from Allen-Bradley, Siemens,

Schneider Electric, Modicon, and many more. Web-based

groov

puts mobile-ready gadgets at your fingertips. Tag them from your

existing tag database, and they automatically scale for use on any

device with a modern web browser. See

for more

information and your free trial.

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 user’s guides, and OptoForums.

In addition, hands-on training is available for free at our Temecula,

California headquarters, and you can

register online

.
