Industrial relay line offers excellent contact reliability
Our new line of industrial relays is available in 24 VDC, 120 VAC and 240 VAC coil voltages. The relays feature bifurcated contacts for excellent contact reliability and low-current switching capability. Prices for the relays start at $4.50.
New models added to EZTouch line of touch panels
The EZTouch line of operator interface panels now includes color 10 and 15-inch slim bezel models. The new panels are also available with pre-installed MODBUS Plus, DeviceNet or Ethernet I/P interface modules. The 15-inch panel (with serial protocol support) is just $2,999 and the 10-inch is $1,899.
EZText Multiplexer connects up to five text panels
The new EZMultiplexer (EZ-MULTIDROP) connects up to five EZText panels to a single PLC. Any combination of panel models can be used and each panel may have a unique configuration. Only the PLC settings are common to all five panels. The multiplexer is priced at $299.
Teach-in pushbutton offers instant calibration in 12 mm photoelectric sensors
Several 12mm photoelectric sensors are now available with a built-in teach pushbutton, for instant calibration using a target object. They are available in diffuse, retroreflective and through-beam sensing styles and in axial cable or quick-disconnect models. Prices for the sensors start at $23.
Prices lowered on industrial monitors
AutomationDirect is able to pass on reductions in electronic component pricing to you by lowering our FLI and FPM industrial monitors prices by $20 to $400, with the same or better quality and features. For example, the 18-inch touch model has been lowered $400 to just $2,295. Our industrial monitors feature quality LCD screens and controllers with auto-scaling, auto-adjust, and wide viewing angles.
24 VDC power supply offers flexible mounting and saves panel space
The FA-24PS-90 24 VDC compact power supply accepts 95-135 or 190-264 VAC input (selectable) and provides up to 3.7 A continuous output current. The power supply can be panel or DIN-rail mounted and the compact 4.5" by 3" footprint saves panel space. It also features brownout protection, overvoltage and overload protection, and thermal and overshoot protection. It is priced at $69.
USB serial converter connects serial devices to PC applications
Our new USB to RS-232 converter transparently connects serial devices to PC applications via a USB port. The unit features flexible cable and ergonomic molding for easy connections, and is great for users who need to connect to a serial port-based peripheral from a laptop PC that has an available USB port, but no serial port. The converter is industry-standard color coded for easy installation, and offers an LED indicator for power and TX/RX. It is priced at $24.95.

Top-secret features revealed: GS-EDRV Ethernet communication module
communicates with MODBUS TCP/IP and has a built-in Web server
by Carl Tolbert, Tech Support
Well, these features are not really "top secret". But in technical support, we sometimes feel that certain features just wind up that way. Take our GS AC drives for example. Pareto's principle (otherwise known as the 80:20 rule) dictates that 80% of users will use the popular H2-ERM (Ethernet networking module) configuration with either an H2-WPLC or DL205 CPU like the D2-260 for networking their drives. The other 20% will use a different, less traditional approach to drive networking solutions. An example of the latter, which takes advantage of a GS-EDRV Ethernet communication module's MODBUS TCP/IP interface, follows:
A user has to add 15 drives to an existing SCADA system. The SCADA package has a MODBUS TCP/IP driver or is OPC/DDE compliant. The rest is very straightforward. Have a look at this application note.
Another little-known feature of the GS-EDRV is the module's built-in Web server. The Web server is a very handy tool for drive configuration and troubleshooting. The drive's IP address can be set up under a "favorites" folder on a Web browser and each drive can be clicked on sequentially. The ease of changing parameters, like acceleration time, is simple and fast. Take a look at page 12 of the GS-EDRV manual for more information.
If you need help with applications such as these, or any other type of application
using our products, AutomationDirect tech support can help. Applications are
just one thing that our technical support department does well. If you have
a question on the feasibility of an application or have a quandary concerning
an existing retrofit, call us at 770-844-4200 or contact

Application: Injection molding machines get productivity boost from DL06 and EZTouch panel
Products used: DL06 PLC, F0-04AD-1 analog input module, 6" EZTouch operator interface
Description: We recently added ten injection-molding machines to our plant. These are high-volume machines that require a material feed and distribution system that will keep up with the demand for material (virgin plastic pellets). I designed a control system using a DL06 PLC interfaced with a 6" EZTouch color touch panel. This system controls two vacuum pumps, six material lines, and 10 feed hoppers. The system can be configured via the touch panel to run two types of material and to control which press to deliver it to. We are also capable of controlling the distribution of material based on frequency of demand. The most useful feature of this system is self-diagnosis of problems and data acquisition. Since vacuum leaks are detrimental and hard to locate on this type of system, I also installed a vacuum transducer on each vacuum system that compares vacuums as each hopper is loading. Any critical reading is written to the touch screen's database. The performance of the system is displayed on the touch screen as a historical trend graph and holds two hours of information. What used to take considerable time to troubleshoot this system now only requires a glance at the touch screen.

The time had come when the father of two sons was to decide who would receive
his fortune. They both kneeled before the aged man as he spoke. "You
will both race your camels to the nearest city. The owner of whichever camel
arrives at the gates second will receive my fortunes." Confused, both
men rode their camels toward the city, step by step, as slow as they could.
As luck would have it, the Great Sage was passing by. Seeing him, they pleaded
for his wisdom. "How might we resolve this such that it doesn't take
the rest of our lives," said the first man. "And yet it must be
in a competitive manner," added the second. "Neither of us are willing
to concede." The Great Sage stroked his beard and shared his wisdom.
On hearing his advice, both men ran back to the camels and raced toward the
city as fast as they could. What was the Great Sage's suggestion? (Go to the
end of this newsletter for the answer.)

"The Lighter Side" answer: The Great Sage told them
to swap camels. It is the second camel, not person, to reach the city gates
