FDOOT241-Ax line separator
Line voltage:
● Nominal DC 32 V (= V
nom
)
● Minimum DC 12 V (= V
min
)
● Maximum DC 33 V (= V
max
)
Voltage at which the line separator opens:
● Minimum DC 7.5 V (= V
SO min
)
● Maximum DC 10.5 V (= V
SO max
)
Permanent current when switches are closed Max. 1.5 A (= I
C max
)
Switching current (e.g., in the event of a short-
circuit)
Max. 2 A (= I
S max
)
Leakage current when switches are open Max. 1 mA (= I
L max
)
Serial impedance when switches are closed Max. 0.4 Ω (= Z
C max
)
The line separator is closed via an actuation signal from the control panel. Required line voltage: DC 12…33 V (normal range)
