CN63100-R1, $197, shown smaller than actual size.
A second setpoint is available on select models to
allow quick selection of a different setpoint setting.
Dual 4-digit displays allow viewing of the process
temperature and setpoint simultaneously. Front panel
indicators inform the operator of the controller and
output status. On many models the main control
output and the alarm outputs are field replaceable.
Optional alarm(s) can be configured to activate
according to a variety of actions (absolute high or low,
deviation high or low, band in or out, with adjustable
hysteresis. A standby feature suppresses the
alarm during power-up until the temperature
stabilizes outside the alarm region. The second
alarm can be configured as a secondary PID output
(heat/cool applications).
The CN63100 Series controller accepts signals from a
variety of temperature sensors (thermocouple or
RTD), precisely displays the process temperature, and
provides an accurate output control signal (time
proportional or linear DC) to maintain the process at
the desired temperature. The controller
comprehensive yet simple programming allows it to
meet a wide variety of application requirements. The
controller operates in the PID control mode for both
heating and cooling, with on-demand auto-tune, which
will establish the tuning constants. The PID tuning
constants may be fine-tuned by the operator at any
time and then locked-out from further modification.
The controller employs a unique overshoot
suppression feature, which allows the quickest
response without excessive overshoot. The unit can
be transferred to operate in the manual mode,
providing the operator with direct control of the output.
The controller may also be programmed to operate in
the “ON/OFF” control mode with adjustable hysteresis.

Accuracies are expressed as ± percentages after 20 minutes warm-up. The controller’s accuracy is
*
specified in 2 ways: accuracy over an 18 to 28°C (64 to 82°F) range at 10 to 75% RH environment;
and accuracy over a 0 to 50°C (32 to 122°F) range at 0 to 85% RH (non-condensing) environment.
Accuracy over the wide sensor range reflects the coefficient of the internal circuitry.
Outputs are independently jumper selectable for either 10V or 20 mA. The output range
**
may be field-calibrated to yield approximately 10% over-range and a small underrange
(negative) signal.
