Pepperl+Fuchs KFA6-DWB-Ex1.D Rotation Speed Monitor

Pepperl+Fuchs KFA6-DWB-Ex1.D Rotation Speed Monitor. 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.

Brand: Pepperl+Fuchs
Categories: Safety Barriers
Model: KFA6-DWB-Ex1.D

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.

The DWB speed monitor is used to monitor the speed or frequency of your plant. Two relays are available for monitoring the limit values, which can optionally be used as MIN or MAX contacts. An additional input is used for start-up override. This means the drive can be started from standstill, even when the MIN monitoring is active.
