产品描述
Starting from Feb 1st 2018, DPiTH Models will be discontinued. As a possible substitute, please check out the ITHX-SD Series for details. At the same time, we will keep the CNiTH Models.|
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. 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 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. 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 digits. The 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 both MODBUS® and a straightforward ASCII protocol. The C4EIT option includes both Ethernet and RS485 ASCII/MODBUS 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 on the Web. |

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.
