The OMEGA® iTH Series instruments monitor and control both temperature and relative humidity. All meters and controllers in the series are high quality, highly accurate instruments featuring Newport's award-winning iSeries technology, uncompromising accuracy, and quality, 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. The OMEGA 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 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 bezel with dual display; the 1/8 DIN vertical, and the 1/8 DIN horizontal with the big bright 21mm digits.
The OMEGA 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.
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 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.

A/D Conversion: 12 bit RH and 14 bit Temperature
Digital Filter: Programmable
Decimal Selection: None, 0.1 for temperature and humidity
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: 250Vac @ 3A or 30Vdc @ 3A (resistive load); Form C SPDT
SSR: 20 to 265Vac @ 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 10Vdc or 0 to 20mA; 500ohm max, accuracy is ±1% of FS
Control Output 1 & 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 & 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.
Network and Serial Communications (options -C24, -C4EI, -EI)
Ethernet: Standards Compliance IEEE 802.3 10Base-T
Supported Protocols: TCP/IP, ARP, HTTPGET
RS-232/RS-422/RS-485: selectable from menu; both ASCII and Modbus protocol selectable from menu. Programmable 300 to 19.2 K baud; complete programmable setup capability; program to transmit current display, alarm status, min/max, actual measured input value and status
RS-485: Addressable from 0 to 199
Connection: Screw terminals
