Not suitable for the evaluation of a
motor thermistor.

With SK 54xE the digital input
(DIN7) can also be used as a digital
output (DOUT3).
If P434 [-05] and P420 [-07] are
parameterised with functions, a High
signal of the DOUT function results
in a High signal for the DIN function.
P434 [-05]

For evaluation in a control system.
The scope of functions corresponds
to that of the relay (P434).

With SK 54xE the digital output
(DOUT2) can also be used as a
digital input (DIN3).
If P434 [-04] and P420 [-10] are
parameterised with functions, a High
signal of the DOUT function results
in a High signal for the DIN function.

Size 1 to Size 4
VI 24V supply
voltage input
18…30V
at least 800mA (input)
Voltage supply for the FI control unit.
This is essential for the function of
the frequency inverter.
Size 5 and above
VO 24V supply
voltageoutput
24V ± 25%
max. 200mA (output)
Supply voltage provided by the
frequency inverter for connection to
the digital inputs or the supply of a
10-30V encoder.
The 24V control voltage is
generated by the FI, however it can
also be supplied via the terminals
X12:44/40. Supply via terminal
X7:44 is not possible.
