PART 1
INTRODUCTION
1.1 Description
The iTH Series instruments monitor and control both tem erature and relative humidity.
• Used with an iTH robe the controller comes with dual dis lays. The to dis lays
relative humidity and the bottom dis lays tem erature. Relative Humidity can be
toggled with Tem erature readings (by ressing the bbutton) or Dew oint readings
(by ressing the cbutton). Dew oint is the tem erature at which water va or from
the air begins to form dro lets and condenses on surfaces that are colder than the
dew oint of air.
• The tem erature and humidity control can be achieved by using on/off or PID
heat/cool control strategy. Control can be o timized with an auto tune feature. The
instrument offers a ram to set oint with timed soak eriod before switching off the
out ut.
The instruments are sim le to configure and use, while roviding tremendous versatility
and a wealth of owerful features. The iTH Series instruments are available either as
monitors or controllers. The monitors are extremely accurate rogrammable digital anel
meters dis laying humidity, tem erature, or dew oint. The controllers also rovide dual
loo control for both humidity and tem erature and are easily rogrammed for any
control or alarming requirement from sim le on-off to full autotune PID control.
The iTH family of meters and controllers are available in four true DIN Sizes with NEMA 4,
IP65 s lash resistant bezels: the ultra com act 1/32 DIN (the world's smallest dual loo
Humidity + Tem erature controller); the o ular midsize 1/16 DIN square bezel with dual
dis lay; the 1/8 DIN vertical, and the 1/8 DIN horizontal with the big bright 21mm digits.
The iTH series LED dis lays can be rogrammed to change color between Green,
Amber, and Red at any set oint or alarm oint.
The iTH controller models offer a choice of two control or alarm out uts in almost any
combination: solid state relays (SSR); Form "C" SPDT (Single Pole Double Throw)
relays; ulsed 10 Vdc out ut for use with an external SSR; or Analog Out ut selectable
for control or retransmission of the rocess value. Universal ower su ly acce ts 90 to
240 Vac. Low voltage ower o tion acce ts 24 Vac or 12 to 36 Vdc.
The Networking and Communications o tions include direct Ethernet LAN connectivity
with an Embedded Web Server, and serial communications. The -C24 serial
communications o tion includes both RS-232 and RS-485. Protocols include both
MODBUS and a straightforward ASCII rotocol. The -C4EI o tion includes both Ethernet
and RS-485 ASCII/MODBUS on one device.
The iTH Series meters and controllers are designed for easy integration with o ular
industrial automation, data acquisition and control rograms as well as Microsoft Visual
Basic and Excel. rovides free configuration and data acquisition software and demos
which makes it fast and easy to get u and running with many a lications.

2.3 Electrical Installation
2.3.1 Power Connections
Caution: Do not connect ower to your device until you have com leted all
in ut and out ut connections. Failure to do so may result in injury!
Connect the main ower connections as shown in Figure 2.4.
Figure 2.4 Main Power Connections
Table 2.3 Fuse Requirement (see specifications)
FUSE Connector Output Type For 115Vac For 230Vac DC
FUSE 1 Power N/A 100 mA(T) 100 mA(T) 100 mA(T)
FUSE 2 Power N/A N/A N/A 400 mA(T)
For the low voltage ower o tion, in order to maintain the same degree of
rotection as the standard high voltage in ut ower units (90 - 240 Vac),
always use a Safety Agency A roved DC or AC source with the same
Overvoltage Category and ollution degree as the standard AC unit (90 -
240 Vac).
The Safety Euro ean Standard EN61010-1 for measurement, control,
and laboratory equi ment requires that fuses must be s ecified based on
IEC127. This standard s ecifies for a Time-lag fuse, the letter code “T”.
The above recommended fuses are of the ty e IEC127-2-sheet III. Be
aware that there are significant differences between the requirements
listed in the UL 248-14/CSA 248.14 and the IEC 127 fuse standards. As a
result, no single fuse can carry all a roval listings. A 1.0 Am IEC fuse
is a roximately equivalent to a 1.4 Am UL/CSA fuse. It is advised to
consult the manufacturer’s data sheets for a cross-reference.
