The CN72000 Series temperature/
process controllers set a new
quality, versatility, ease-of-use and
value standards. Including many
high-level standard features,
additional function setup items
appear in the control menu when a
function is selected, simplifying the
selection process. Units feature a
universal input for thermocouple
Types J, K, E, T, L, N, B, C, S and
R, RTD’s, differential input
(-10 to 10 mVdc); and process input
(0 to 20 mAdc, 0 to 10 Vdc). A
standard 24 V isolated, regulated
power supply is included; operates
most standard 4 to 20 mA
transmitters. Standard features
include autoune, fuzzy logic, fully
adjustable PID, auto/manual control
with smooth transfer and front panel
activation key, percent output
indicator, peak and valley indicator,
loop break protection and indication.
For process inputs, the display is
fully programmable from -1999 to
9999 with selectable decimal point
location. Most thermocouple and RTD inputs show whole or tenth
degree displays. The CN72000
Series can be programmed for
on/off, PID, heat/cool, or latching
alarm. All outputs are isolated from
the inputs. Outputs include 10 A
relay, and scalable 0 to 20 mAdc.
