All meters and controllers in the series are high quality, highly accurate instruments featuring OMEGA’s award-winning iSeries technology, uncompromising accuracy, 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 21 mm (0.87") digits. ## **CNiTH-i8DH33-2** ## _**SENSOR INCLUDED!**_ The OMEGA iTH Series LED displays can be programmed to change color 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 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 RS232 and RS485. Protocols include a straight forward ASCII protocol. The C4EIT option includes Ethernet and RS485 ASCII 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 at OMEGA. ## **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 **CNiTH-i3233-5 All models shown smaller than actual size.** **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** **Two Physical Outputs:** Output 1 = RH, output 2 = temperature; functions are set up as outputs (PID or ON/OFF), or alarms ## **Ordering Outputs Choices:** 250 Vac @ 3 A or 30 Vdc @ 3 A (resistive load); Form C SPDT 20 to 265 Vac @ 0.05 to 0.5 A (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, 500Ω maximum, ±1% of full scale accuracy ## **Control Output 1 and 2** ## **Operation:** 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) **Hu-29** **Hu** **2)** Alarm functions are active, in addition to the color changing functions, if output 1 and 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 and 2 submenus used for PID are eliminated from menu; color sequence based on alarm setpoints is still available ## **Input** **Accuracy/Range @ 25C - Non-condensing:** ±3% for 10 to 90%; ±3.5% for 5 to 10% and 90 to 95% ±4% for 0 to 5% and 95 to 100% **Hysteresis:** ±1% RH **Non-linearity:** ±3% **Temperature Accuracy/Range*** ±0.5°C for 5° to 45°C (±1°F for 41 to 113°F); up to ±1.5°C for -40° to 5°C and 45° to 124°C (up to ±2.7°F for -40° to 41°F and 113° to 255°F) **Resolution:** 0.1%, 12bit for RH; 0.1°C, 14 bit for temperature **Response Time:** 8 seconds, tau 63% for RH; 5 to 30 seconds, tau 63% for temperature _*** Note:** Extended temperature range is for industrial probe only, the controller’s operating temperature is 0 to 50°C._ ## **Network and Serial Communications (For Options -C24, -C4EIT, -EIT)** **Ethernet:** Standards compliance IEEE 802.3 10Base-T **Supported Protocols:** TCP/IP, ARP, HTTPGET **RS232/RS422/RS485:** 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 **RS485:** Addressable from 0 to 199 **Connection:** Screw terminals ## **General** **A/D Conversion:** 12-bit RH and 14-bit temp **Reading Rate:** 2 samples per sec max **Digital Filter:** Programmable **Decimal Selection:** None, 0.1 for temperature and humidity **Display:** 4-digit, 9-segment LED **i32, i16D, i8DV:** 10.2 mm (0.40") **i8:** 21 mm (0.83") **i8DH:** 10.2 mm (0.40") and 21 mm (0.83") **RED** , **GREEN** and **AMBER** programmable colors for process variable, setpoint and temp units **Operating Temperature:** 0 to 50°C (32 to 122°F), 90% RH non-condensing **Protection:** **i32, i16D:** NEMA 4X (IP65) front bezel **i8DH, i8DV:** NEMA 1 (IP23) front bezel **Power:** Refer to ordering guide **==> picture [314 x 205] intentionally omitted <==** **----- Start of picture text -----**
