Overview / Design Principle:
The 6170+ temperature controller incorporates our advanced
tuning algorithms, with selectable pre-tune and self-tuning for
easier setup. The self-tune also reduces output activity to an
absolute minimum without compromising control quality, thereby
reducing wear and tear on mechanical components such as valves,
contactors and relays. In test, these controls have cut down
valve oscillation from 30 to 40 times a minute to just a few.
Pre-tune plus self-tuning has also been shown to get on control
up to 3 times faster.
Our Plug and Play Technology allows you the ability to
easily add to the temperature controller’s features including
communication by simply installing additional plug-in boards.
Inputs, Outputs, Alarms, and Communications are all field
upgradeable! This allows you to only pay for the options that
are required on todays applications.
The temperature controller is also easy to setup, with an
innovative configuration port for off line programming directly
from a PC or through a simplified operator’s front panel. Access
can also be limited by either a security code or by setpoint
options.
