control without depending
on vulnerable valve position
slidewire feedback.
Universal Input
A universal input circuit with
an advanced A-D converter
samples the input at 9Hz and
continuously corrects it for drift,
giving high stability and rapid
response to process changes.
A filtered input covers all
thermocouple types, Pt100
3-wire RTD and linear inputs.
The patented Instant Accuracy
feature allows precise input
measurement and control to be
achieved from the moment of
start up, independent of warm-up
drift, and even during periods of
ambient temperature upset.
Easy Operation
Bright, clear front-panel LED’s
display the process variable and
a configurable lower display for
setpoint or other important
parameters. Tactile pushbuttons
ensure positive operation. All
instrument parameters are easy
to access and may be presented
to the operator or hidden from
view under password protection.
The 2208e is a 1/8 DIN controller
that may be configured either
as a precision PID temperature
controller or a velocity mode
motorized valve positioning
controller. The two control
modes are co-resident and may
be selected through factory or
field configuration. The 2208e
features modular hardware, two
control outputs, two digital
inputs, self-tuning, a simple
ramp-dwell setpoint programming
feature and optional relay alarms
and communications port. The
control outputs may be
configured for heat/alarm,
heat/cool or for valve open/close
Precise Control
Advanced PID or valve
positioning algorithms give
stable straight-line control of
the process. A power feedback
feature automatically
compensates the output to
stabilize the temperature of
electrically heated loads during
supply voltage fluctuations.
Proprietary cooling algorithms
ensure optimum control of fan,
oil and water-cooled systems.
Velocity mode valve control
algorithms allow precise valve
