Power Supply

The CN8200 temperature/process
controller is extremely versatile and
user-friendly. During setup, the user
needs to review only those
parameters relevant to the particular
application. A dual digital display
offers optimal process information at
a glance. Individual LEDs identify
the status of outputs, alarms, digital
communications, and special
options. The CN8200 features a
NEMA 4X front panel and a

universal power supply that
accepts 100 to 250 Vac and
120 to 250 Vdc. A 24 Vac/24 Vdc
power supply option is also
available. Available control
algorithms are P, PI, PD, PID, or
on/off. The autotune feature
automatically sets proportional
band, derivative, and integral
before the process reaches
setpoint. These parameters
provide quick stabilization of
processes with minimum overshoot,
hunting, or cycling. Eight-level
ramp/soak control is standard and
includes a decimal display on
thermocouple ranges, digital
display and signal filtering, and a
percentage of power limit setting.

The dual control outputs can be
configured for a variety of control
and alarm applications, and
2 dedicated alarm outputs are
also available.

The CN8200 offers a wide range
of options, including RS232 and
RS485 digital communications,
3 contact/digital input modes,
4 transducer excitation voltages,
and 4 auxiliary output ranges.
