SNAP I/O
About Opto 22 SNAP I/O Family
Looking for reliable input/output (I/O) modules for your automation system?
Firstly, SNAP I/O Family of products is an excellent choice. Proven in the field, SNAP I/O has been trusted since 1996. It is well-suited for discrete control, process control, almost any industrial control, remote monitoring, or data acquisition application. Specifically designed for harsh environments. All are transformer isolated and optically isolated from the field side to the control side. Importantly, isolated input modules or output modules offer channel-to-channel isolation. Additionally, analog modules each contain 2 to 32 channels of I/O—software configurable by channel. This means a small number of modules can handle a wide range of inputs.

Industrial I/O Processors (Brains)
Affordable and compact, the SNAP PAC R-series programmable automation controllers provide powerful, real-time control and communication. As a result, they support your industrial control, monitoring, Industrial Internet of Things (IIoT), and data acquisition needs. Integrated seamlessly within the SNAP PAC System™, the R-series PAC is a rack-mounted, industrially hardened unit capable of handling multiple tasks. These tasks include digital and analog control, serial string handling, communication, and enterprise connectivity.
When used with the included PAC Project Basic software suite (or PAC Project Professional, purchased separately), the controller becomes highly versatile. In fact, the Ethernet-based SNAP PAC R-series controller runs control programs written in Opto 22’s PACControl™ software. It is also capable of monitoring and controlling a wide range of devices and equipment wired to the I/O on its own rack. Additionally, it extends control to I/O on distributed racks equipped with SNAP PAC EB-series brains or groov RIO edge I/O modules.
Analog I/O Modules
Part of the SNAP PAC System Family, SNAP analog output modules mount on SNAP PAC racks along with other I/O modules and a SNAP PAC brain or R-series controller.
Additionally, analog output modules have an on-board microprocessor to provide module-level intelligence, making them an ideal choice for Original Equipment Manufacturers (OEMs). Secondly, these software-configurable output modules handle a wide variety of signal levels. Thirdly, most provide dual-channel packaging, all SNAP analog modules are factory calibrated.
Digital (Discrete) I/O Modules
Opto 22 SNAP I/O 4-channel digital input modules are part of the SNAP PAC System. Importantly, 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. In addition, digital input modules can sense either AC or DC signals.
Moreover, 4-channel digital modules have removable top-mounted connectors to provide easy access for field wiring, and all operate on 5 VDC control logic. For ease of use, each digital module features integral channel-specific LEDs for convenient troubleshooting and maintenance. Finally, every module is factory tested twice and is UL and CE approved.
Serial I/O Modules
Serial SNAP communication modules are specifically designed for use with the SNAP PAC System. Additionally, they can be used in I/O units without a controller.
By using a SNAP serial communication module as a converter, non-Ethernet devices can connect to an Ethernet network. As a result, they become available for control, monitoring, and data acquisition by any authorised PC or device on the network.
Moreover, all SNAP serial communication modules snap directly into Opto 22 SNAP PAC mounting racks. They fit right beside SNAP I/O® digital and analog modules. This setup provides the right mix of analog, digital, and serial channels needed at any location.
Mounting Racks
SNAP PAC I/O mounting racks are specifically designed to hold an intelligent SNAP I/O processor. This includes a SNAP PAC brain or a SNAP PAC R-series on-the-rack controller. In addition, these racks can support several I/O modules.
Furthermore, all SNAP analog, digital, and serial I/O modules share the same footprint. As a result, customers using SNAP PAC racks can easily mix all these modules on a single I/O mounting rack. For added convenience, field devices are wired directly to the top-mounted connectors on each module. Alternatively, they can be wired through breakout boards when additional space is necessary.
Opto 22
Founded in 1974 by engineers who designed a better solid-state relay and chose to build it in a non-corporate, flat organisation. Fast forward 50 years, they are still privately held, lead, and run by engineers. Opto 22 products are designed to run on non-proprietary communication standards like Ethernet, the Internet Protocol (IP), MQTT, and more. Open standards and commercially available technologies decrease your cost of automation and open up data for use where you need it. As a result, over the years, they have had a hand in promoting industry standards.
