dual parameters, such as a limiting
value (high/low alarm), incremen-
ting, pulse separator or error mes-
sage output

KFU8-UFC-Ex1
KFU8-UFC-Ex1.D
The universal frequency converter con-
verts an input frequency into a frequen-
cy proportional current and offers at the
same time the possibility, to monitor the
limit values.
The frequency values for the minimum
(0 or 4 mA) and the maximum output
current (20 mA) are freely parameteriz-
able.
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 out-
put, 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 galvani-
cally isolated.
The universal voltage power pack al-
lows the operation of the KFU8-UFC-
Ex1... 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 sur-
face and by means of the software, the
version KFU8-UFC-Ex1 only by means
of the software.
