The BRAUN High Safety Protection System Series E16x346 is TÜV certified for SIL3 acc. IEC 61508:2010 and is API 670 Ed.5 and API 612 Ed.7 compliant. It provides protection against overspeed and detects reverse direction. Also up to six other trip criteria such as emergency stop, boiler protection, etc. can be included in the trip string.
Due to its globally unique and true 2oo3 architecture, the system will tolerate one faulty signal within each trip criterion without trip being released.

Single Channel for 1001, 1002, 2002 Solutions
♦ Fast, precise and safe
♦ Maintenance-free during Lifetime, therefore minimized TCO
♦ Increased safety with 1oo2 architecture
♦ Maximum availability with 2oo2 architecture
♦ Universal range of application, throughout mechanical and electrical engineering, in the chemical industry, in power plants, and at test stands
With single channel processing (1oo1) security provision is solely determined by the device configuration. Therefore the use of sensor monitoring with integrated plausibility control is essential. In such a case no redundancy is provided. Should a fault be detected, the entire system will be shut down immediately.
With two channel systems, there is a choice of implementation, dependent upon requirements. In principle, the two monitors operate in parallel yet independently. Alarm indication can be realized through the linkage of their Safety Outputs.
For 1oo2 processing, we have system redundancy with enhanced security through comparative diagnosis. In the case of fault detection, the entire system will be shut down. With 2oo2 processing, we still have system redundancy but with enhanced availability. Only if both monitors fail, the system as a whole will be shut down.
The E16521D.1 Speed Monitor permanently monitors the speed sensor for its correct function. During its complete useful lifetime of 20 years, the Monitor does not require any external proof tests and is completely maintenance-free.
