Description
This product series is no longer available. For possible alternates please see CN38S or CN4000_SERIES. An exact replacement will be introduced in Q1 2021.
Monitor and control temperature
or process applications with
precision using the CN142 Series
controllers. The CN142 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, and
also includes alarm, event and
timer functions with optional
RS485 communications. 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.
