产品描述
The CN245-Series has been discontinued. For a possible alternate, please see
CN401-11445-C4 as an alternative
.
Monitor and control temperature or
process applications with precision
using the CN245 Series DIN rail
mountable controllers. The CN245
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, RS485 communications
and heater loop break alarm.
Beside operation as multi-setpoint
PID controller, the unit can be
ideally used as signal converter
thanks to a universal input
(selectable by parameter for up
to 18 different signals) and the
analog output which is galvanically
isolated and programmable for
rescalable retransmission of
process/setpoint value.
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 module
without power applied to controller.
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.
