Humidity and Temperature Controllers TM U utput 1: Humidity, O Output 2: Temperature U igh Accuracy ±0.5°C H and ±2% RH U Popular DIN Sizes 4 U Ethernet and Serial Communications (Optional) U ser-Friendly, Simple U to Configure U ull Autotune PID F Control U Choice of Relays, SSR, DC Pulse, Analog Voltage and Current U rogrammable Ramp and P Soak for Humidity and/or Temperature U H/Temperature Probe R Included U oHS 2 Compliant R The OMEGA iTH Series instruments monitor and control both temperature and relative humidity. All 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 controllers 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. TM The iTH family 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. 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 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.
