OPTO 22 Products

MasTec has distributed OPTO 22 since the mid 1990s and highly recommends all their products.

OPTO 22 is one of the world's premier innovators and suppliers of advanced Industrial Automation and IIOT.

Opto 22 manufactures hardware and software products that link all kinds of electrical, mechanical, and electronic devices and machines to networks and computers.

Opto 22 controllers, I/O, solid-state relays, and software are used for industrial automation, remote monitoring, data acquisition, and M2M applications.

Their products make it possible for you to use your normal business computer systems to monitor, control, and get data from all the devices and machines that are important to your business, on the production floor or even more remotely.

Their products translate the data between computers and other machines. This translation works easily and inexpensively because they design Opto 22 products to run on non-proprietary communication standards like Ethernet and the IP.

You will find if you are building PAC based solutions, in almost all cases OPTO 22 will the lowest cost and the most flexible of all current solutions on the market. And of course you get OPTO 22 legendary isolation and tough I/O.

Ask for a quote before you run off and buy some companies PAC system that doesn't have the long experience OPTO 22 has (since 1972).

OPTO 22 has an excellent HMI product "groov" and it is now included in the new "groov EPIC system"

 I/O  Controllers  IO4AB - IO for Allen Bradley  EMU = Energy Management Unit



Analog, digital, and serial Input/output (I/O) modules, I/O processors (brains), mounting racks, power supplies for I/O, and packaged systems.

Opto 22 I/O is famous for its reliability. Most modules are guaranteed for life.

PAC :-Programmable automation controllers for remote monitoring, control, and data acquisition. Also power supplies and adapter cards used with controllers.

Opto 22 controllers can monitor simple devices or automate an entire factory.

IO4AB :-The perfect companion for your Allen-Bradley® System

SNAP I/O from Opto 22 extends your A-B PLC system with distributed Ethernet I/O where you need it, plus advanced process control features.

With ControlLogix® and CompactLogix® PLCs, use our distributed intelligence to shift I/O scanning and control to the local I/O level. Or add new, reliable, low-cost analog and digital I/O to SLC 5/05 and MicroLogix systems.

The OptoEMU Sensor Energy Monitoring Unit quickly & easily collects energy data from your building, electrical subpanels, and individual high-energy use equipment like chillers and compressors.

OptoEMU then delivers the data so you can view it online and use it in your business and control applications.

With real-time and historical energy data clearly in view, you can eliminate guesswork and pinpoint problems—and reduce energy costs.

 More on Software      

The PAC Project Software Suite from Opto 22 provides all the software you need for industrial automation, process control, building automation, remote monitoring, data acquisition, and Industrial Internet of Things (IIoT) applications in any field. One of four components of the SNAP PAC System, PAC Project software is fully integrated with SNAP PAC controllers, brains, and I/O, making it easy to understand, select, buy, and apply an automation system for your needs.

Easy to use and suitable for projects from simple equipment management to full industrial control, PAC Project Professional includes the following:

 - PAC Control Professional, a full-featured, flowchart-based tool for developing control programs to run on SNAP PAC controllers
- PAC Display Professional, for creating human-machine interfaces (HMIs) for operators and technicians to monitor and interact with the SNAP PAC System
- PAC Manager, a utility program for configuring and maintaining SNAP PAC controllers, brains, and I/O
- OptoOPCServer, a fast and efficient server for communication with all OPC 2.0-compliant clients
- OptoDataLink, for sharing SNAP PAC System data with commonly used databases, including Microsoft(R) SQL Server, Microsoft Access, and MySQL
- SoftPAC, a software-based programmable automation controller (PAC) designed for PC-based control

About controller redundancy: PAC Project Professional 9.0 supports controller-level redundancy. Controller redundancy is distinct from network link redundancy, which has been supported for some time.

 - Network link redundancy provides a backup network connection in case the network should fail; it provides a second communication route for the controller.
- Controller redundancy, in contrast, provides a backup controller that takes over running the strategy in the unlikely event that the first controller fails. In addition to PAC Project Pro 9.0, controller redundancy requires two identical S-series PACs and the SNAP PAC Redundancy Option Kit.

Developer and IIoT ready: Because Opto 22 SNAP PAC R-series and S-series controllers include an HTTP/HTTPS server and a RESTful API (application program interface based on the REST architecture), you can securely access I/O point and variable data in your PAC Control program using the language of your choice. Data is returned in JSON format. For complete information, see

 NOTE: If you do not need complex network architectures, redundant controllers, support for legacy Opto 22 FactoryFloor systems, OPC communication, or database connectivity, you may find that the free PAC Project Basic Software Suite provides everything you need.
