Wireless I/O module pair
This pair of wireless I/O modules requires no software or PC connection and can be driven by either dc or ac signal sources.
Model WWP-IIRO-8 is a pair of intelligent 16-channel digital I/O units that communicate directly with each other. Each unit contains 8 Form C (SPDT) electromechanical relays and 8 optically isolated digital inputs. When an isolated input is toggled on one of the units, it will cause the corresponding relay to switch on the other unit. No software or PC connection is required as this solution is completely self-contained and operates autonomously. The units are packaged in small, rugged, NEMA4 enclosures, and offer a low-cost alternative to costly signal wire installations. They can operate at distances up to 7 miles line-of-sight via a 900 MHz wireless connection (up to 20 miles with optional high-gain antenna). The eight isolated inputs can be driven by either dc sources of 3-31 V (or higher by special order), or ac sources at frequencies of 40 Hz to 10 kHz and are not polarity sensitive.

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
