4.6 "Active" signal
The "Active" signal (pin 7) is an optocoupler output that has a low resistance during the discharging of the
buffer capacitors.
For a connection schematic, refer to the illustrations in the chapter Operating diagrams [ } 17] and
Connection diagrams.
Signal voltage Max. 60 Vdc Voltage between pins 6 and 7
Signal current Max. 6 mA
Voltage drop across
optocoupler 1.2 V /
3.3 V At 1 mA / 5 mA while optocoupler has a low resistance
Leakage current Max. 50 µA While optocoupler has a high resistance
Insulation voltage

4.7 "Ready" signal
The "Ready" signal (pin 8) is an optocoupler output that has a low resistance when the buffer capacitors are
fully charged.
For a connection schematic, refer to the illustrations in the chapter Operating diagrams [
}
17] and
Connection diagrams.
Signal voltage Max. 60 Vdc Voltage between pins 6 and 8
Signal current Max. 6 mA

4.8 Inhibit input
The buffering can be inhibited or interrupted with the "Inhibit" input (pin 9). To do this, pin 6 must be
connected to the positive pole of the terminal voltage or to the external control voltage and pin 9 must be
connected to the corresponding negative pole.
The inhibition of the device also results in the discharging of the internal capacitors. The capacitors cannot
be charged as long as the buffer module is in inhibit mode.
For a connection schematic, refer to the illustrations in the chapter Operating diagrams [ } 17] and
Connection diagrams.
Signal voltage Max. 60 Vdc Voltage between pins 6 and 9
Signal current Max. 4 mA Current limited
Inhibit mode The device does not buffer (or stops buffering) if the voltage between pin 6 and pin
9 is higher than 10 V. The buffering functions again below 6 V.
