The OMEGA™ iSD-TC provides Web-based temperature monitoring in critical equipment and locations such as computer server rooms, clean rooms, laboratories, museums,
warehouses, or any remote facility.
View and record temperature on two independent thermocouple channels, over an Ethernet network or the Internet with no special software—just a Web browser.

Email Alarms
The device can trigger an alarm if temperature goes above or below a set point that you determine. Your alarm can be sent by email to a single user or to a group distribution list,
including text messages to cell phones and PDA’s.
Physical Threats
The iSD-TC includes screw terminals for two contact closures that work with common alarm sensors. You can instruct the iSD monitor to send an alarm if a door is opened, a window is broken,
or a fire sprinkler goes off.
Power Failure
The iSD monitor can trigger an alarm if the AC power fails. The iSD-TC will continue to collect data for two days powered by a standard 9 Volt alkaline battery (included). A failure on the
Ethernet network will not interrupt data recording.
Local Alarms
The iSD monitor includes two 1.5 Amp output relays that are controlled by the alarm conditions you select. The relays can trigger flashing lights and a siren for example to alert personnel
near the scene. With the easy Web-based setup page, the two relays can be programmed for two temperature inputs, and high or low set points, as well as alarm conditions triggered by contact closures.
The relays can also be programmed to turn off when conditions return to normal, or programmed to remain latched and require a manual reset.

View Charts and Graphs on the Web
The iSD serves Active Web Pages to display real time readings, display charts of temperature, or log data in standard data formats for use in a spreadsheet or data acquisition program such as Excel
or Visual Basic.
The virtual chart viewed on the web page is a JAVA™ Applet that records a chart over the LAN or Internet in real time. With the iSD, there is no need to invest time and money learning a proprietary
software program to log or chart the data.
Chart scales are fully adjustable on the fly. For example, the chart can display one minute, one hour, one day, one week, one month or one year. Temperature can be charted across the full span or
within any narrow range.

The iSD can display and chart absolute measurements in two locations and a differential measurement between the two locations.The iSD can take thermocouple types J, K, T, E, R, S, B, C, N,
and L measuring temperatures up to 1820°C (3308°F). The iSD includes a pair of type K thermocouples.

Link to Web CAM or IP Camera
The Web page includes a link to a "Web Cam" or "IP camera" (not included). If you get a message about an alarm condition, you can quickly click on the link to view the actual scene over the Internet.

|
SD Flash Memory Card
The iSD comes complete with a removable SD Flash Memory card that can store up to years of readings taken at ten second intervals.
Records on SD Flash Cards
The data is recorded on widely available SD (Secure Digital) flash cards. The format is a simple ".txt" text file that is easily imported to spread sheets and other programs.
It can be read directly on a PC or MAC with a USB card reader.
You can also download the data remotely over an Ethernet network or the Internet.
Installation and operation of the iSD monitor requires no special training, tools, or software. The device connects to any Ethernet network with standard cable and plugs and is powered
by any AC outlet supplying 110 to 240 Vac.

Award-Winning Technology
The iSD is simple to install and use, and features Omega's award-winning iServer technology that requires no special software except a Web Browser.
The iSD connects to an Ethernet Network with a standard RJ45 connector and sends data in standard TCP/IP packets.
It is easily configured with a simple menu using a Web Browser and can be password protected. From within an Ethernet LAN or over the Internet, the user simply types its IP address or an
easy to remember name such as "Cleanroom 5" or "Midwest Server Room" in any Web Browser, and the iSD-TC serves a Web Page with the current readings.
Typical Applications
The iSD is great for monitoring temperature in applications such as: clean rooms, computer rooms, HVAC systems, pharmaceutical and food processing and storage, hospitals, laboratories,
semiconductor fabs, electronic assembly, warehousing, museums, manufacturing, farm animal shelters, greenhouses, and many more.
