Intrinsically-Safe Ethernet (!?)
Weed Fiber-Optics Switched Media Converter Weed Fiber-Optics is now offering UL-approved Class I, Div. 2 (Non-Incendive) rated Switched Media Converters and Switches (hubs) to extend Ethernet into or through hazardous rated areas. The EOTec 2000 Series Switched Media Converters and Switches allow you to easily implement an Ethernet 'trunk line'. By simply cascading a pair of converters on a DIN-rail and supplying 24VDC external power, you can go in and out of a 'drop' location with fiber-optic cable, running at 100 MHz, and 'pick-up' two 10/100 Ethernet devices at each location. Because they are actually Ethernet Switches, this scheme can be duplicated many times without the need for repeaters.

MTL Introduces New Zener Barrier Series!

New MTL 7700 Series MTL has developed a new 'old' series of zener-barriers- I'll explain- The new 7700 Series is derived from the venerable 700 Series. A few of the key features of the new barrier series are:

• Electrically Compatible with the MTL 700 Series
• DIN-Rail Mounting and Grounding
• Un-Pluggable Terminals
• Hybrid Barriers for Switches with Isolated Outputs
• Bussed Power Feature
• Electronic Fusing Feature
• Very Competitively Priced!

The internal electrical components and terminations are identical to the widely used and accepted 700 Series. Because terminations, entity parameters, etc. are exactly the same, this allowed them to be easily 'grandfathered in' at all the approval agencies such as FM. The "new" part of the 7700 Series is the DIN-rail mounting and grounding (like the MTL 7000 Series); unpluggable terminals (unique to zener-barriers); jumper power bussing. Also unique to the 7700 Series are several models for switch or prox (NAMUR) interface with relay outputs (SSR or hard contact). The 7700 Series is now the lowest cost barrier series in MTL's zener barrier 'family'. To substitute the newer 7700 Series barrier, just add a '7' in front of the previous 700 Series model number (i.e., a 728+ becomes a 7728+); it's that easy!

Unfortunately, the 7700 Series introduction was too late to be included in the new catalog, but we have a brochure available describing the 7700 Series features. Click Here to download a copy of the MTL 7700 Series brochure in Adobe Acrobat Adobe Acrobat .PDF Logo format.

The MTL 7700 Series is now in full production and completely stocked in Hampton, NH. Contact TenTech if you have a current or upcoming need for zener barriers and would like to consider this new barrier series for your application.

'Thin' is 'In!' - Daisy Data Offers NCD Thin Clients!
NCD Logo Not everyone is yet familiar with "thin clients", so I have referenced a condensed "primer" for your education, reference and review
on this .PDF file Adobe Acrobat .PDF Logo.

Now that Intellution and Wonderware (and others) have "jumped on the bandwagon" and made their HMI and SCADA software compatible to thin-client architecture, there has been an intensive interest in what this technology offers towards industrial processing applications.

Daisy Data has been selling thin-clients for a great number of years now- mostly in the form of X-terminals through their VAR partnership with Tektronix. About two years ago, the "Video & Networking Division" of Tektronix was acquired by NCD making NCD the largest thin-client manufacturer in the world. In fact, thin-client hardware and management software is NCD's only business. Daisy Data now continues the relationship with NCD which has been expanded to include Windows-based "network computers" (both the Citrix ICA and Windows Terminal Server RDP protocols) as well as compatibility with the older-technology Wyse terminals or VT100's. NCD's terminals are Windows CE compliant and can be purchased with an integrated IE web browser.

Here's a link to a recent Industrial Computing article on thin clients that just appeared in the September, 2001 issue:

http://isa.org/journals/ic/feature/1,1162,649,00.html

Here's another link to a previous Industrial Computing article on thin clients (there are some side-bar articles noted at the end, also):

http://www.isa.org/journals/ic/feature/printable/1,1171,565,00.html

Contact TenTech if you would like to explore thin clients for your current workstation or operator interface application. We would be happy to quote you pricing on either simple office-grade thin clients or fully ruggedized Daisy Data workstations.
