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.
