The new network LED Dimmer from Opto 22 uses pulse width modulation technology (PWM) to control brightness from 0-100 percent for 9-30 to control VDC constant voltage LED lighting assemblies such as lamps, bulbs, strips, ropes and bars. It can also be used for other resistive-type loads. (Source: Opto 22)
Al, this is an interesting approach, and as you point out it is flexible and extensible. One thing it does bring to light (pun intended) is that controlling LEDs is much more complex than the systems they replace. On the other hand, with the electronics we have available now, it is not a problem to develop and integrate systems such as this.
In a lot of vehicles today, the interior lights dim as you prepare to drive, or when leave the vehicle and close the door. I do wonder if LEDs have been able to do that up tp now. This technology would be important for those applications, I would think.
Cabe, Very surprising that serial communications wouldn't be a topic that everyone would be exposed to. But I guess it is simple enough that young engineers can get up-to-speed on their own if they need to
Practically all electronic devices today contain metals that may
be coming from conflict-ravaged African countries. And political pressures will increasingly influence how these minerals are sourced and used in products.
Weaned on the relatively effortless connectivity of today’s massive variety of consumer electronic products, automation users in the IIoT will likely not tolerate too many competing, piecemeal standards for long. And the Industrial Internet Consortium is trying to preempt history.
