PART 1

INTRODUCTION

1.1 Description

The iTH Series instruments monitor and control both temperature and relative humidity.

• Used with an iTH probe the controller comes with dual displays. The top displays
relative humidity and the bottom displays temperature. Relative Humidity can be
toggled with Temperature readings (by pressing the bbutton) or Dewpoint readings
(by pressing the cbutton). Dewpoint is the temperature at which water vapor from
the air begins to form droplets and condenses on surfaces that are colder than the
dewpoint of air.

• The temperature and humidity control can be achieved by using on/off or PID
heat/cool control strategy. Control can be optimized with an auto tune feature. The
instrument offers a ramp to setpoint with timed soak period before switching off the
output.

The instruments are simple to configure and use, while providing tremendous versatility
and a wealth of powerful features. The iTH Series instruments are available either as
monitors or controllers. The monitors are extremely accurate programmable digital panel
meters displaying humidity, temperature, or dew point. The controllers also provide dual
loop control for both 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 of meters and controllers are available in four true DIN Sizes with NEMA 4 /
Type 4, IP65 splash resistant bezels: the ultra compact 1/32 DIN (the world's smallest dual
loop Humidity + Temperature controller); 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 21mm digits.

The iTH series LED displays can be programmed to change color between Green,
Amber, and Red at any set point or alarm point.

The iTH controller models offer a choice of two 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. Universal power supply accepts 90 to
240 Vac. Low voltage power option accepts 24 Vac or 12 to 36 Vdc.

The Networking and Communications options include direct Ethernet LAN connectivity
with an Embedded Web Server, and serial communications. The -C24 serial
communications option includes both RS-232 and RS-485. Protocols include both
MODBUS and a straightforward ASCII protocol. The -C4EI option includes both Ethernet
and RS-485 ASCII/MODBUS on one device.

The iTH Series meters and controllers are designed for easy integration with popular
industrial automation, data acquisition and control programs as well as Microsoft Visual
Basic and Excel. provides free configuration and data acquisition software and demos
which makes it fast and easy to get up and running with many applications.

2.3 Electrical Installation

2.3.1 Power Connections

Caution: Do not connect power to your device until you have completed all

input and output connections. Failure to do so may result in injury!

Connect the main power 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 power option, in order to maintain the same degree of
protection as the standard high voltage input power units (90 - 240 Vac),
always use a Safety Agency Approved DC or AC source with the same
Overvoltage Category and pollution degree as the standard AC unit (90 ­240 Vac).

The Safety European Standard EN61010-1 for measurement, control,
and laboratory equipment requires that fuses must be specified based on
IEC127. This standard specifies for a Time-lag fuse, the letter code “T”.
The above recommended fuses are of the type 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 approval listings. A 1.0 Amp IEC fuse
is approximately equivalent to a 1.4 Amp UL/CSA fuse. It is advised to
consult the manufacturer’s data sheets for a cross-reference.

, Alarm 1 is

triggered at the Setpoint plus any offset placed in the Alarm Hi value.

Below: In Absolute Mode, Alarm 1 is triggered when the process variable is less
than the Alarm Low Value (Hi value ignored). In Deviation Mode, Alarm 1 is
triggered at the Setpoint plus any offset placed in the Alarm Low value.

Hi/Low: In Absolute Mode, Alarm 1 is triggered when the process variable is less
than the Alarm Low Value or above the Hi Value. In Deviation Mode, Alarm 1 is
triggered when the process variable is less than the Setpoint minus any offset in
the Alarm Low or greater than the Setpoint plus any offset in the Alarm Hi value.

Band: Alarm 1 is triggered when the process variable is above or below the
"band" set around Setpoint 1. Band equals Hi Value (Low Value ignored). A
"band" is set around the Setpoint by the instrument only in the "Deviation" Mode.

The Band for the AL 1 would be following the Setpoint 1 value
The Band for the AL 2 would be following the Setpoint 2 value.
The Band or the Deviation Value should be entered under:

AL1 High (if they want Alarm 1)
AL2 High (if they want Alarm 2)
AL Low value is ignored in the Band mode.

Example: if customer requires a Deviation Value of ±10 degrees around a
setpoint (using Output 2 as alarm)

Alarm 2: - Deviation
Contact Closure type: Deviation---Band
AL2 High: 10 (Band they want around Setpoint 2)

Then the Band Value is to be entered under AL2 HI: 10 not 80+10 = 90
