I/O and terminal bocks appear healthy

Aug. 11, 2006
This month’s roundup on I/O and terminal blocks demonstrates that the industry seems to be recuperating, product development money is flowing, and companies are getting competitive again.

By the CONTROL Staff

WE PRESENTLY see a wide range of I/O and interfaces for everything from Ethernet and wireless to Profibus, ArcNet, and Modbus. On the terminal block and connector side, innovations and enhancements prevail.

Other than a new emphasis on wireless and Ethernet connections, we don’t see any hard trends in I/O, connectors or terminal blocks. Instead, now that companies are recovering from their economic doldrums, we’re seeing a healthy mix of products of all types coming down the new product chute.

PSD14 Series 14-W, DC-DC, power-over-Ethernet splitter provides 12.5 W from standard IEEE 802.3af power sourcing equipment (PSE). The splitter is a power supply that can be mounted next to an Ethernet device, and is compliant with IEEE 802.3af standards. Typical applications include IP telephones, wireless network access points, Bluetooth access points, security cameras, and IP print servers. More info at controlglobal.com.
