Please see the NEW CN401-11445 for a product with similar price and more advanced features!
Temperature Controller with Thermistor Inputs that allows you to monitor and control temperature
or process applications with
precision. The CN243 Series
provides dual LED displays for
local indication of process value
and setpoint value. Control
methods include on/off, PID,
auto-tune and manual-tune.
Controller includes a 3-setpoint
ramp/soak control feature, alarm
functions with optional RS485
communications heater loop
break alarm. Analog output can
be programmed for either control
or retransmission of process
variable. An optional software
package CN-SW-HW-KIT includes
cable and configuration module
for quick configuration of units,
as well as copying configuration
parameters from one unit to
another. The configuration module
can also be purchased separately
and with a built-in battery feature,
configuration settings can be
downloaded and copied to the
module without power applied
to controller. The module can
then be plugged into a new unit
without power applied and the
configuration setting can be
transferred for easy set-up for
multiple units.
