The RUG9 PLC is currently
the most powerful and
expandable PLC in a long
line of RUGID PLCs designed
for remote data acquisition
and control applications. It
incorporates advanced
hardware and software
techniques so you can
implement your application in
minimal time. Numerous hardware
and software safeguards are incorporated
into the design so you can be assured that
the unit will continue to operate for many years
in the most demanding field environment.

All RUG9s are optically isolated and come standard with 256K of battery backed RAM and 512K of program flash.

Operator Interface
  • The built-in operator interface (optional) uses familiar prompts and engineering units, eliminating operator guesswork and code memorization.
  • The LCD can show trends, bargraphs, time-tagged event logs, realtime data, setpoints, etc.
  • The 20 line by 40 character (6" diagonal) local backlit display can scroll through several screens of information with a single key press.
  • For greater ease of use, the LCD display can be mounted locally on the card cage or remotely up to 5 feet away.
  • The cage mounted LCD swings out to allow easy access to cards and wiring.
  • Sealed tactile keyboard enables setpoint and mode changing.
