Remotely resettable electronic circuit breaker

The E-T-A ESX10-TC is a 12 V DC version of the 24 V ESX10-T and is designed for SCADA/RTU applications, providing protection for switch-mode power supplies and solar/battery-based systems.

E-T-A expanded its line of electronic circuit protection products with the ESX10-TC, a 12 V dc version of the ESX10-T, 24 V dc product offering and is designed for SCADA/RTU applications – providing protection for 12 V dc switch-mode power supplies and solar/battery based systems.

The most unique feature of ESX10-TC, E-T-A said, is the ability to remotely reset the device from outside an enclosure. This can be accomplished via a simple momentary push button or from an output of an RTU or PLC controller. In RTU/SCADA applications, equipment is primarily located in remote unpopulated locations. The remote reset functionality reduces the need for field engineers to travel to sites to troubleshoot equipment – reducing the overall cost of equipment maintenance and downtime.

The ESX10-TC is available in fixed current ratings from 1 A to 10 A and provides selective load protection - ensuring exclusive disconnection of the current path in the event of an overload or short circuit in the field load device without compromising the dc 12 V power source (such as battery drain).

The ESX10-TC limits the short circuit current to 1.3 to 1.8 times rated current and disconnects 100 ms after the fault has been detected. Inrush peaks are tolerated from capacitive loads of more than 20,000 μF and is designed with an auxiliary output to provide individual alarm capabilities for critical process flow applications. This space-saving device has a width of only 12.5 mm and 80 mm in height and depth. Its low power consumption makes it ideally suited for battery-buffered dc 12 V applications, specifically in the solar industry.

The ESX10-TC is DIN rail ready and can be mounted either individually or in a group side-by-side with a simplistic bus bar system for +12 V dc and ground. It also uses the same screw terminals as its 24 V dc counterpart which allows up to a 10 mm² conductor to be wired directly to the device, this ensures reliable and safe wiring connections.

Annual Salary Survey

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.
