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 is an excellent choice. Field-proven since 1996, SNAP I/O is suited for discrete control, process control, almost any industrial control, remote monitoring, or data acquisition application.
Designed for harsh environments. All are transformer isolated and optically isolated from the field side to the control side. Isolated input modules or output modules offers channel-to-channel isolation. Further, analog modules each contain 2 to 32 channels of I/O—software configurable by channel meaning 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. Suporting to meet your industrial control, monitoring, Industrial Internet of Things (IIoT), and data acquisition needs. Integrated within the SNAP PAC System™, the R-series PAC is a rack-mounted, industrially hardened unit capable of handling multiple tasks. Of which involve digital and analog control, serial string handling, communication, and enterprise connectivity.
Used with the included PAC Project Basic software suite (or PAC Project Professional, purchased separately), the Ethernet-based SNAP PAC R-series controller runs control programs written in Opto 22’s PACControl™ software. Capable of monitoring and controlling a wide range of devices and equipment wired to the I/O on its own rack. Further 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.
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. 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.
4-channel 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. Every module is factory tested twice and is UL and CE approved.
Serial I/O Modules
Serial SNAP communication modules are designed for use with the SNAP PAC System. In addition, they can also be used in I/O units without a controller. Using the SNAP serial communication module as a converter, non-Ethernet devices can be connected to an Ethernet network.
Further being available for control, monitoring, data acquisition by any authorised PC or other device on the Ethernet network. All SNAP serial communication modules snap into Opto 22 SNAP PAC mounting racks right beside SNAP I/O® digital and analog modules. Providing the mix of analog, digital, and serial channels you need at any location.
Mounting Racks
SNAP PAC I/O mounting racks are designed to hold an intelligent SNAP I/O processor—a SNAP PAC brain or a SNAP PAC R-series on-the-rack controller—and several I/O modules.
Since SNAP analog, digital, and serial I/O modules all have the same footprint, customers using SNAP PAC racks can mix all these modules on the same I/O mounting rack. Field devices are wired directly to the top-mounted connectors on the modules plugged into each rack, or through breakout boards when additional wiring space is required.
