Pepperl+Fuchs KFU8-UFC-Ex1.D frequency converter with trip values. The device is a universal frequency converter that changes a digital input signal into a proportional free adjustable 0/4 mA ... 20 mA analog output signal and functions as a switch amplifier and a trip alarm. This isolated barrier is used for intrinsic safety applications.

The functions of the switch outputs (2 relay outputs and 1 potential free transistor output) are easily adjustable [trip value display (min/max alarm), serially switched output, pulse divider output, error signal output].

The device is easily configured by the use of keypad or with the PACTware configuration software. A fault is signalized by LEDs acc. to NAMUR NE44.
