**Virtual Chart Recorder Web Server** **Alarms by Email or Text Message No Special Software Required Record Years of Data on Popular SD Cards** ## **Web-based Remote Surveillance of Temperature + Humidity and Security** The **NEWPORT[®] iSD** environmental monitor provides Web-based remote surveillance of environmental conditions in critical HVAC applications such as computer server rooms, clean rooms, laboratories, museums, warehouses, or any remote facility. View and record Temperature, Relative Humidity and Dew Point 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 or humidity 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 NEWPORT iSD 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 monitor 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 NEWPORT 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 any combination of temperature or humidity, 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. 1 ## **VIEW CHARTS AND GRAPHS ON THE WEB** The NEWPORT iSD serves Active Web Pages to display real time readings, display charts of temperature and humidity, or log data in standard data formats for use in a spreadsheet or data acquisition program such as Excel or Visual Basic. Readings Address http://192.168.1.200 Readings Web Link Setup ———— ~~EE~~ HTML Java **Temperature 23.0 C Humidity 47.3% Dewpoint 11.0 C Contact1 NORMAL Contact2 ACTIVE Output ACTIVE LOW Recording ON Refresh** —— 2 **Seconds** Auto Update Chart 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 NEWPORT 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 and humidity can be charted across the full span (-40 to 124°C, and 0 to 100% RH) or within any narrow range such as (20 to 30°C). **==> picture [149 x 89] intentionally omitted <==** **----- Start of picture text -----**

## **SD FLASH MEMORY CARD** The iSD comes complete with a removable 2 GB SD Flash Memory card that can store up to seven 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. ## **SENSOR AND CALIBRATION** The iSD monitors come complete with a plug-in temperature and humidity probe that mounts on the instrument or separately with the six foot extension cable (included). It is not necessary to take the iSD monitor out of service for routine calibration. The temperature / humidity sensors are interchangeable and can be replaced for about the same cost as a typical calibration. NEWPORT offers replacement sensors with optional 3-point NIST traceable calibration certificates. **==> picture [70 x 87] intentionally omitted <==** **----- Start of picture text -----**

## **Optional Caps for Industrial Probes, iSDTHP-5** Installation and operation of the NEWPORT 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 NEWPORT iSD is simple to install and use, and features NEWPORT's award-winning iServer technology that requires no special software except a Web Browser. ## **View temperature and humidity over Ethernet or the Internet.** 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 serves a Web Page with the current readings. ## **TYPICAL APPLICATIONS** ## **Datalogging spreadsheet** The NEWPORT iSD is great for monitoring temperature + humidity 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, greenhouses, farm animal shelters, and many more. NEWPORT iServer products are designed and manufactured in Santa Ana, California. 2 ## **Sensor Specifications** ## **Power** **Probe Physical Dimensions Standard Probe Dimensions:** ## **Input:** 9 to12 Vdc **Safety qualified ac power adapter, included:** ## **Relative Humidity (RH)** Ø13 x 83.8 mm lg (Ø 0.5 x 3.3” lg) **Industrial Probe iSDTHP-5** : Probe: Ø16 x 137 mm lg (0.63 x 5” lg) Housing material: SS 316 Cable length 3m (10’) Cable operating temperature: -40 to 125°C (-40 to 257°F) **Accuracy/Range:** ±2% for 10 to 90% ±3% for 5 to 10% and 90 to 95% ±4% for 0 to 5% and 95 to 100% **Non-linearity:** ±3% **Hysteresis:** ±1%RH **Response Time:** 8 seconds, tau 63% **Repeatability:** ±0.1% **Resolution:** 0.1%, 12 bit **Nominal Output:** 9 Vdc @ 0.5A **Input:** 100 to 240 Vac, 50/60Hz **Back-up Battery:** 9Vdc, Alkaline **Embedded WEB Server** Serves WEB pages containing real-time data and live updated charts within definable time intervals **Software** OPC Server; macro for datalogging in Excel program; compatible with Windows operating systems ## **iServer Specifications** ## **Interfaces** **Temperature (T) Accuracy/Range* Wand Probe:** ±0.5°C for 5 to 45°C (±1° for 41 to 113°F); ±0.5 to ±1°C for 0 to 5°C and 45 to 60°C (±1 to ±2° for 32 to 41°F and 113 to 140°F) **Industrial Probe:** (see temperature chart in the manual) ±0.5°C for 5 to 45°C (±1° for 41 to 113°F); ±0.5 to ±1.5°C for -40 to 5°C and 45 to 124°C; (±1 to ±2.7° for -40 to 41°F and 113 to 255°F) **Ethernet (RJ45):** Fixed or autonegotiating 10/100BASE-T, Auto MDI/MDIX **Protocols** TCP, UDP, SNMP, SMTP, NTP, ARP, ICMP, DHCP, DNS, HTTP, and Telnet ## **Environmental** ## **Operating Temperature:** |**LCD Display**32 Digits 4.8 x 9.7mm
