Connection of FieldbusBox modules

The connection of the Fieldbus Box modules is done direct or via a T-piece (or Y-piece).

The B318 series does have a male and female connector, that means no external T-piece is required. The supply
voltage (+5V

DC

) for the termination resistor is only supplied via the female M12 connector. The termination resistor

ZS1000-1610 is only available with male connector, therefore the incoming PROFIBUS line should end in a female
connector.

Two T-pieces are available:

ZS1031-2600 with +5VDC on male and female connector for the termination resistor

ZS1031-2610 with +5VDC only on the female connector
