Pepperl+Fuchs KFD2-UFC-Ex1.D Frequency Converter with Trip Values
This isolated barrier is used for intrinsic safety applications.
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.
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 and a separate collective error message output.
