Newport iTH-i16 Humidity and Temperature Controller
The Newport iTH Series can monitor and control both temperature and humidity. These monitors digital panel meters can display humidity, temperature, or dew point. The iTH controllers are easy to program any control or alarming requirement from simple on-off to full autotune PID control.
4 DIN sizes of the meters and controllers:
- Ultra compact 1/32 DIN
- Midsize 1/16 DIN square bezel with dual display
- 1/8 DIN vertical
- 1/8 DIN horizontal with the big bright 21 mm digits
The iTH LED display colors can change between GREEN, AMBER, and RED at any setpoint or alarm point
The iTH controller models gives you 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.
These meters and controllers are intended for simple incorporation with popular industrial automation, data acquisition and control programs as well as Microsoft Visual Basic and Excel. Available to download on the Web Newport provides free configuration software which makes it quick and simple to get up and running.

Technical Specifications
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.
