Product Description
Noris DWA70-1
The Noris DWA70-1 is a highly reliable electronic speed monitor and overspeed switch, designed as part of the NORISYS 4 automation system. It is engineered for the critical task of monitoring and protecting engines, turbines, generators, and other rotating machinery from overspeed conditions. This compact unit processes frequency signals from various speed sensors and triggers relay outputs when pre-set speed limits are exceeded, enabling pre-warning alarms or emergency shutdowns. Its robust design and DIN rail mounting make it ideal for demanding industrial and marine applications where safety and operational integrity are paramount.
Technical Specifications:
