Fast, precise and safe - from zero motion to highest speed
The BRAUN Single Channel Speed Monitor Series E16521 D for increased safety require-
ments is SIL2 / IEC 61508:2010 compliant. It monitors motors, pumps, feeders, gears,
rollers and small turbines and provides protection against overspeed at any required
value of rotational speed, including standstill
With single channel processing (1oo1) security provision is solely determined by the
device configuration. Therefore the use of sensor monitoring with integrated plausi-
bility 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 status signal outputs
For 1 oo2 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 entire system will be shut down
The E16521D Speed Monitor permanently monitors the speed sensors for their correct
function. During its complete lifetime cycle the monitor does not require any externa
proof tests and is completely maintenance-free.
BENEFITS
■ Fast, precise and safe
■ Maintenance-free during Lifetime,
therefore minimized TCO
■ Universal range of application,
throughout mechanical and electrica
engineering, in the chemical industry,
in power plants, at test stands
■ Increased safety with
1oo2 architecture
■ Maximum availability with
2oo2 architecture
