Electronic overload relay

Siemens' 3RB24 electronic overload relay is designed to reduce machine downtime and improve logistics, the company said.

07/26/2011


With the reported successful launch of Sirius Innovations, Siemens has released the Sirius 3RB24 electronic overload relays featuring a new communication technology IO-Link. 

Contactors, connected to the Sirius 3RB24, reportedly provide integrated motor protection and superior communication advantages, including readout of motor current and diagnostics. Rotary switches allow for easy setting of the device's motor current and the required trip class. A consortium made up of the leading suppliers of automation products has come together to support the new concept in all areas of sensors, actuators and control technology. IO-Link apparently represents an open, standardized and manufacturer-independent system for the uniform connection of sensors and switching devices to the control level.

"The Sirius 3RB24 is designed to reduce machine downtimes and optimize planning of maintenance measures, in addition to the added confidence of diagnostic measures like ground fault tripping, overload, thermistor protection tripping in a higher level control," says John Burns, product manager, of Siemens Industry's Automation Division. "This product combines easy system documentation, optimization of system processes and flexibility for on-site control and monitoring."

According to Burns, a direct customer benefit is the product's simple configuration for a communication capable product. "Most power controls are more complicated to set up. When compared to typical fieldbus overload relays, the 3RB24 is much simpler to configure while providing full control and diagnostic capability."

The 3RB24 is part of a comprehensive line of cabinet based control products including motor control and monitoring relays that have IO-link communication capability, Siemens said.

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.
