Single Channel Speed Monitor E16521D.1 for increased safety requirements up to SIL2

The BRAUN Single Channel Speed Monitor E16521D.1 for increased safety requirements is SIL2 / IEC 61508:2010 compliant. It monitors motors, pumps, feeders, gears, rollers and small turbines. The device provides protection against overspeed at any required value of rotational speed, including standstill.
The specially designed signal input fits perfectly to our proven Differential-Hall-Effect based A5S… sensors.

With single channel processing (1oo1) safety 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.
