The frequency values for the minimum (0 or 4 mA) and the maximum output current (20 mA) are freely parameterizable. Also the functions of the switch outputs (2 relay and 1 potential free transistor output) are freely adjustable [limit value indication (MAX- or MIN-alarm), serially switched output, pulse seperator output, error signal output]. A start-up override that can be activated externally is integrated as well. The maximum input frequency is 5 kHz. Input and output currents are galvanically isolated. The universal voltage power pack allows the operation of the KFU8-UFCEx1... at various supply voltages at the same terminals, without change-over or consideration of the polarity. The version KFU8-UFC-Ex1.D can be adjusted by means of the control surface and by means of the software, the version KFU8-UFC-Ex1 only by means of the software.
