With our new solid-state Network LED Dimmer, you can control low voltage LED lamps, bulbs, strips, bars, and rope through your RS-485 serial network, using DMX512-A, Modbus/ASCII, or Optomux protocols.
Our latest OptoMinute video introduces the Dimmer and shows you how it works.

If you've ordered PAC Project automation software recently, you've noticed a change: we're now delivering these software products as downloads only.
In the past, when you purchased PAC Project Professional or any of its components, you could download the software from the Opto 22 website and then we shipped you a CD and printed documents.
But many of you have told us that the printed documents are costly to ship and arrive later, and most of you use help files in the software or the PDF documents included in the download, rather than the printed books.
So, starting January 1, 2013, you will simply download the software and docs. We will ship you an envelope containing evidence of purchase (required by many receiving departments), together with the product password for your records. If you do need printed books, you can obtain one free copy of printed documents by emailing your request to email@example.com.
This way you receive your software and documents right away. If you don't want hardcopy documents, you don't need to pay for shipping them or give them storage space. But if you want them, we'll send you the most up-to-date ones quickly.
This change affects the following part numbers:
If you need printed documents, email your request to firstname.lastname@example.org.

Automation World magazine readers have chosen Opto 22 as one of their "First Team" suppliers in Automation World's Leadership in Automation 2012 program.
Opto 22 won the award in three categories:
- Programmable Automation Controllers
- Data Acquisition Hardware
- HMI iPad Apps
Awards were based on online voting and a year-long email poll. We thank you for your vote and will continue to provide you with excellent products—like SNAP PAC controllers, OptoEMU Sensor energy monitoring units for detailed energy data, and the Opto iPAC app to put your automation system in your hand. We'll also continue to provide free, expert product support to make sure our products perform the way you need them to.
This is the second year of Automation World's Leadership in Automation award program. Nearly four dozen categories indicate the wide variety of automation technologies,
software, and products in use by today's manufacturing professionals across the discrete, batch, and continuous process manufacturing industries.
All the Leadership in Automation First Team Honorees are recognized in Automation World's January 2013 issue.
Here's a good New Year's resolution: resolve to check the voltage to your I/O racks and maintain stable voltage for safety and better performance.
The power supplies you use to power your I/O racks are a key piece of your system. Without adequate power you may lose communication with I/O modules and lose data in the brain. But too much power can destroy your control equipment.
Make sure power to I/O racks is maintained at a steady 5.0 to 5.2 volts DC. Measure power voltage downstream of the fuse on the rack itself, following the steps in our short video, Verifying Voltage at the I/O Rack. If you have an adjustable power supply, adjust the voltage so that it measures ~5.15 VDC downstream of the fuse on the rack.
Here are some other power supply tips:
1. We recommend SNAP power supplies for SNAP PAC Systems. These Opto 22 power supplies are regulated and isolated, and preadjusted to 5.1 VDC at the factory. They are also compact, efficient, don't generate a lot of heat, and have an on/off switch built in.
2. If you cannot use Opto 22 power supplies, choose a linear power supply or an isolated switching power supply.
3. Always keep power for the control system separate from power for field devices.
4. For best results, use one power supply per I/O rack.
5. If you must power more than one I/O rack with the same power supply, never wire them in series. Voltage drops off at the far end or may be too high at the first rack.
If you wire in parallel (star configuration), use similar short lengths of wire and racks that have a similar current draw. A rack with more analog or serial modules draws more current than a rack with 4-channel digital modules. Make sure to measure voltage at each rack.
6. Use the largest gauge wire practical. Use 14 AWG wire between the power supply and the I/O rack.
