Starting from Feb 1st 2018, DPiTH Models will be discontinued. As a possible substitute, please check out the ITHX-SD Series for details. At the same time, we will keep the CNiTH Models.
The OMEGA™ iTH Series
instruments monitor and control both
temperature and relative humidity. All
controllers in the series
are high quality, highly accurate
instruments featuring Omega’s
award-winning iSeries technology,
uncompromising accuracy, backed by
an extended 5-year warranty.
The instruments are simple to
configure and use, while providing
tremendous versatility and a wealth
of powerful features.
With two full channels of PID control, these instruments are the perfect choice for environmental control applications such as test chambers, clinical storage, computer rooms, etc.
The iTH Series Controllers provide
single output control for humidity
and temperature and are easily
programmed for any control or
alarming requirement from simple
on-off to full autotune PID control.
The iTH family controllers are available in four true
DIN sizes: the ultra compact 1/32 DIN;
the popular midsize 1/16 DIN square
bezel with dual display; the 1/8 DIN
vertical, and the 1/8 DIN horizontal with
the big bright 21 mm digits.
The iTH Series LED displays
can be programmed to change color
between GREEN, AMBER, and RED at any setpoint or alarm point.
The iTH controller models offer a
choice of 2 control or alarm outputs
in almost any combination: solid state
relays (SSR); form “C” SPDT (single
pole double throw) relays; pulsed 10
Vdc output for use with an external
SSR; or analog output selectable
for control or retransmission of the
process value.
The networking and communications
options (highly recommended)
include direct Ethernet LAN
connectivity with an embedded Web
server, and serial communications.
The C24 serial communications
option includes both RS232 and
RS485. Protocols include both
MODBUS® and a straightforward
ASCII protocol. The C4EIT option
includes both Ethernet and RS485
ASCII/MODBUS on one device.
The iTH Series
controllers are designed for easy
integration with popular industrial
automation, data acquisition and
control programs as well as Microsoft
Visual Basic and Excel. Omega
provides free configuration software
which makes it fast and easy to get up
and running. Available for download
on the Web.

Control
Action: Reverse (heat) or direct (cool)
Modes: Time and amplitude proportional control modes; selectable manual or auto PID, proportional, proportional with integral, proportional with derivative with anti-reset windup and ON/OFF
Rate: 0 to 399.9 seconds
Reset: 0 to 3999 seconds
Cycle Time: 1 to 199 seconds; set to 0 for ON/OFF operation
Gain: 0.5 to 100% of span; setpoints 1 or 2
Damping: 0000 to 0008
Soak: 00.00 to 99.59 (HH:MM), or OFF
Ramp to Setpoint: 00.00 to 99.59 (HH:MM), or OFF
Autotune: Operator initiated from front panel for 1 input at a time only
Outputs
There are two physical outputs: Output 1 = RH, Output 2 = Temp
Functions are set up as Outputs (PID or ON/OFF), or Alarms
Ordering output choices:
Relay: 250 Vac @ 3A or 30 Vdc @ 3A (resistive load); Form C SPDT
SSR: 20 to 265 Vac @ 0.05 - 0.5A (resistive load); continuous
DC Pulse: Non-Isolated; 10 Vdc @ 20 mA (used with external SSR)
Analog Output (Output 1 only): Non-Isolated, control or retransmission 0 to 10 Vdc or 0 to 20 mA;
500 ohm max, accuracy is ±1% of FS
Control Output 1 and 2
Operation:
Action: Reverse (heat) or Direct (cool)
Modes: Time and Amplitude Proportional Control Modes; selectable Manual or Auto PID, Proportional, Proportional with Integral, Proportional with Derivative with Anti-reset Windup and ON/OFF
Alarm 1 and 2 (Programmable)
1) Alarms are used for color changing sequence of alarm status (visual alarm).
2) Alarm functions are active, in addition to the color changing functions, if Output 1 & 2 are (menu) disabled.
3) If Alarms are disabled, Output menus (PID or ON/OFF) are active. Color change is still active.
Operation: High/low, above/below, band, latch/unlatch, normally open/normally closed and process/deviation; front panel configurations
-AL Limit Alarm Version: Output 1 & 2 submenus used for PID are eliminated from menu. Color sequence based on alarm setpoints is still available.
