Electronic Timer Relay (ETR) is a 22.5-mm narrow module which allows the user to adjust all timingfunctions via front potentio-meter and DIP switch array. The relay also features a broad time range of 40 msec to 2,500 sec, and "universal" input voltage of 18 to 285V ac/dc. The ETR's industrial housings are DIN-rail-mountable, and single lines are securely connected from a screw connection technology.

Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
Norway-based additive manufacturing company Norsk Titanium is building what it says is the first industrial-scale 3D printing plant in the world for making aerospace-grade metal components. The New York state plant will produce 400 metric tons each year of aerospace-grade, structural titanium parts.
