Product Characteristics
4.4 SCALANCE X206-1
Range
The maximum transmission range (segment length) is 3 km.
Connectors
The cables are connected over BFOC sockets.
4.4.6 SCALANCE X206-1 Power Supply and Signaling Contact
Power Supply
The power supply is connected using a 4-pin plug-in terminal block. The power supply can
be connected redundantly. Both inputs are isolated. There is no distribution of load. When a
redundant power supply is used, the power supply unit with the higher output voltage
supplies the SCALANCE X206-1 alone. The power supply is connected over a high
resistance with the enclosure to allow an ungrounded set up.

Warning
The SCALANCE X206-1 is designed for operation with safety extra-low voltage. This means
that only safety extra-low voltages (SELV) complying with IEC950/EN60950/ VDE0805 can
be connected to the power supply terminals.
The power supply unit to supply the SCALANCE X206-1 must comply with NEC Class 2
(voltage range 18 - 32 V, current requirement 350 mA)
The signaling contact can be subjected to a maximum load of 100 mA (safety extra-low
voltage (SELV), DC 24 V).
Never connect the SCALANCE X206-1 to AC voltage or DC voltage higher than 32 V DC.
Signaling Contact
The signaling contact is connected to a 2-pin plug-in terminal block. The signaling contact
(relay contact) is a floating switch with which error/fault states can be signaled by breaking
the contact.
