The OMEGA® CNi8DH and CNi8DV
are high-quality, highly accurate
single loop autotune PID temperature
and process controllers for 1⁄8 DIN
(92 x 45 mm) horizontal or vertical
panel cutouts. Both devices feature
the same state-of-the-art technology,
uncompromising accuracy, and
quality backed by an extended
5-year warranty.

The CNi8DH and CNi8DV are
simple to configure and use, while
providing tremendous versatility and
a wealth of powerful features.

The CNi8DH and CNi8DV come
standard with your choice of
2 control or alarm outputs in almost
any combination: solid state relays
rated at 0.5 A @ 120/240 Vac;
Form “C” SPDT relays rated at
3 A @ 120/240 Vac; pulsed 10 Vdc
output for use with an external SSR;
or analog output (0 to 10 Vdc or
0 to 20 mA) selectable for control or
retransmission of the process value.

The universal temperature and
process instrument (CNi8 models)
offer a selection of 10 thermocouple
types as well as 2-, 3- or 4-wire
RTDs, process voltage and current.
The CNi8DH and CNi8DV are ideal
controllers for use with transmitters
and amplified transducers. Built-in
excitation is standard (24 Vdc
@ 25 mA). The units handle
0 to 20 mA process current and
process voltage in 3 scales:
0 to 100 mV, 0 to 1V, and 0 to 10V.

As with all iSeries devices, the process
value display can be programmed
to change color between GREEN,

AMBER, and RED at any setpoint

or alarm point. The LEDs displaying

digits of any 1⁄8 DIN controller.

The strain/process instrument
(model iS) meters and controllers
measure inputs from load cells,
pressure transducers, and most any
strain gage sensor. Input ranges
include 0 to 100 mVdc; -100 mVdc
to 1 Vdc; 0 to 10 Vdc in addition to
0 to 20 mA. Excitation for transducers
of 5 V and 10 V is standard.

The highly recommended networking
and communications options include
direct Ethernet LAN connectivity
with an embedded Web server, and
serial communications. The C24
serial communications option
includes both RS232 and RS485
which can be selected from the
menu as well as both a

integration with popular industrial
automation and control programs
as well as Microsoft Visual Basic
and Excel. OMEGA
