Description

The temperature and humidity controllers of the iTH Series are available either as indicators or controllers. The indicators are extremely accurate programmable digital panel meters displaying humidity, temperature, or dew point. The controllers also 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 of meters and controllers are available in four true DIN sizes: the ultra compact 1/32 DIN; the popular midsize 1/16 DIN square model 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 colour 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 analogue 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 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. Omega provides free configuration software which makes it fast and easy to get up and running. Available for download on the Web.


SPECIFICATIONS

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

Alarm 1 and 2 (Programmable)
1) Alarms are used for colour changing sequence of alarm status (visual alarm).
2) Alarm functions are active, in addition to the colour changing functions, if Output 1 & 2 are (menu) disabled.
3) If Alarms are disabled, Output menus (PID or ON/OFF) are active. colour 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. colour sequence based on alarm setpoints is still available.
