Harrisburg, Pa. —Outputs of this series of two primary switched power supplies can be connected in parallel without using any external blocking diodes. This allows users to build a redundant power system which eliminates interrupted control power when a power supply fails. A variety of inputs and outputs are available.
In the first NASA-supported mission to the moon in 25 years, 26 Silicon Valley firms together created the recently launched Lunar Prospector spacecraft. Led by Lockheed Martin Missiles & Space, the firms created the first peer-reviewed, competitively selected mission in NASA's Discovery Series.
To alleviate false triggering from background objects, Banner Engineering Corp. recently unveiled a new adjustable-field photoelectric sensor that allows users to detect objects within a sensing field, while more effectively ignoring reflective objects beyond the sensing field cutoff point.
SBS Bit 3 Operations recently appointed David Greig as president, and also moved to its new 40,000 ft2 facility in St. Paul. Mr. Greig was previously founder and president of Greig Power Co. Ltd. (Toronto, Ontario, Canada), which was later acquired by Perle Systems Ltd. He served as president of Perle's customer engineering division, and also worked simultaneously as...
Things will be busy in Houston, Tex., this fall. On October 18-21, ISA will manage the ElectroTech/98 show concurrently with its ISA Expo/98, and these will coincide with the first IEC annual meeting held in the U.S. in 25 years. ElectroTech/98 will highlight electrical and electronic components, power supplies, PC boards, and other OEM products.
Ithaca, N.Y. —The TTM610 module employs 300 MHz PowerPC 603e and 604e microprocessors. Up to 128 MBytes of SDRAM and a communications processor are on-board. These modules can be placed on Transtech's VME, PCI, or ISA host interface boards, thereby offering multi-PowerPC processor solutions in a variety of form factors.
Development Implementation A great deal of momentum has been generated toward the implementation of OMAC-based control systems. GMPTG is actively assisting the development of OMAC technologies and aggressively working with the suppliers to commercialize OMAC products. This document outlines the development and implementation strategies, and they are summarized here: Development adopt available standards and interface specifications; participate and/or follow existing development activities; leverage government funding and coordinate government projects to accelerate the development of OMAC; utilize government's influence to define strawman common API; invite third party vendors to finalize and support the common API specifications; interact with international open architecture development activities to advance OMAC technologies; Implementation expose OMAC direction to control system suppliers; integrate and validate commercial open controller products; resolve machine tool specific OMAC issues; cooperate with machine tool OEMs to implement OMACs; expose 'open' technologies to plant personnel; develop partners to support plant implementations. It should be clear that GMPTG is not taking a wait-and-see attitude in implementing OMAC technologies and is introducing OMAC systems in manufacturing operations with well defined approaches to minimize the risk. Active participation in efforts to accelerate the development of OMAC technologies is important and GMPTG is also defining the strategies to utilize diverse control products effectively.
Fullerton, Calif.—Micro 8000 can record 8,000 plus time-stamped temperature measurements in a wide variety of applications, including transit and warehousing, energy surveys, and isolated enclosure equipment monitoring. Uses a low-power microprocessor to re-cord data into nonvolatile memory and operates on a 3.
Menlo Park, Calif.— MoniTrace 200N heat tracing control and monitoring system is said to lower installation and maintenance costs and improve reliability of electrical heat tracing systems. Intended for industrial use, the system is capable of controlling one or two groups of circuits for temperature maintenance and freeze protection.
