Description

Description

The trodeks® iTH Seriesinstruments monitor and control bothtemperature and relative humidity. Allmeters and controllers in the seriesare high quality, highly accurateinstruments featuring trodeks’saward-winning iSeries technology,uncompromising accuracy, backed byan extended 5-year warranty.

The instruments are simple toconfigure and use, while providingtremendous versatility and a wealthof powerful features. With two full channels of PID control, these instruments are the perfect choice for environmental control applications such as test chambers, clinical storage, computer rooms, etc.

The iTH Series instrumentsare available either as monitorsor controllers. The monitors areextremely accurate programmabledigital panel meters displayinghumidity, temperature, or dewpoint. The controllers also providesingle output control for humidityand temperature and are easilyprogrammed for any control oralarming requirement from simpleon-off to full autotune PID control.

The iTH family of meters andcontrollers are available in four trueDIN sizes: the ultra compact 1/32 DIN;the popular midsize 1/16 DIN squarebezel with dual display; the 1/8 DINvertical, and the 1/8 DIN horizontal withthe big bright 21 mm digits.

The iTH Series LED displayscan be programmed to change colorbetween GREEN, AMBER, and RED at any setpoint or alarm point.

The iTH controller models offer achoice of 2 control or alarm outputsin almost any combination: solid staterelays (SSR); form “C” SPDT (singlepole double throw) relays; pulsed 10Vdc output for use with an externalSSR; or analog output selectablefor control or retransmission of theprocess value.

The networking and communicationsoptions (highly recommended)include direct Ethernet LANconnectivity with an embedded Webserver, and serial communications.The C24 serial communicationsoption includes both RS232 andRS485. Protocols include bothMODBUS® and a straightforwardASCII protocol. The C4EIT optionincludes both Ethernet and RS485ASCII/MODBUS on one device.

The iTH Series meters andcontrollers are designed for easyintegration with popular industrialautomation, data acquisition andcontrol programs as well as MicrosoftVisual Basic and Excel. trodeksprovides free configuration softwarewhich makes it fast and easy to get upand running. Available for downloadon the Web.


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.
