Rotation Speed Monitor KFA6-DWB-Ex1.D
1-channel isolated barrier
230 V AC supply
Dry contact or NAMUR inputs
Input frequency 1 mHz ... 5 kHz
2 relay contact outputs
Configurable by keypad
Line fault detection (LFD)
Up to SIL 2 acc. to IEC 61508/IEC 61511
This isolated barrier is used for intrinsic safety applications. It monitors for an overspeed or underspeed condition of a discrete signal
(NAMUR sensor/mechanical contact) from a hazardous area by comparing the input frequency to the user programmed reference frequency.
An overspeed or underspeed condition is signaled via the relay outputs. Line fault detection of the field circuit is indicated by a red LED and relay.
The start-up override feature sets relay outputs to default conditions programmed by the user for up to 1,000 seconds.
The unit is easily programmed by the use of a keypad located on the front of the unit.
