Introduction
The affordable and compact SNAP PAC R-series
programmable automation controllers provide
powerful, real-time control and communication to
meet your industrial control, monitoring, and data
acquisition needs. Part of the Opto 22 SNAP PAC
System
™
, the R-series PAC is a rack-mounted,
industrially hardened unit that can handle
multiple tasks involving 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 PAC Control
™
software. It can monitor and control a wide range of devices and
equipment wired to the I/O on its own rack and to I/O on distributed racks equipped with
SNAP PAC EB-series brains. Alternatively, the R-series controller can be used as a slave to a
larger, SNAP PAC S-series standalone industrial controller.
SNAP PAC R-series controllers are well suited to original equipment manufacturers (OEMs),
system integrators, and end-users in process control, discrete manufacturing, or hybrid
industries and applications.
Six models of the SNAP PAC R-series controller are available:
• SNAP-PAC-R1 , SNAP-PAC-R1-FM , and SNAP-PAC-R1-W each control a mix of SNAP
analog, digital (both standard and high-density), and serial modules. Full digital
functions include high-speed counting, quadrature counting, pulse measurement, and
period and frequency measurement. The -FM model is Factory Mutual approved. The
-W model adds wireless LAN capability (see
“Wired+Wireless Communication” on
page 2 for more information).
• SNAP-PAC-R2 , SNAP-PAC-R2-FM , and SNAP-PAC-R2-W also control a mix of SNAP
analog, standard and high-density digital, and serial modules. High-speed digital
