85 to 260 V AC: 0.8 A slow-blow / 250 V
20 to 55 V AC and 16 to 62 V DC: 2 A slow-blow / 250 V
Fieldbus connection Check the data cable:
Terminal 26 = FF +
Terminal 27 = FF

Fieldbus connector
(Option) • Check pin assignment/wiring

• Check connection between connector/fieldbus port.
Is the coupling ring tightened correctly?
Fieldbus voltage Check that a min. bus voltage of 9 V DC is present at terminals 26/27. Permissible range: 9
to 32 V DC
Network structure Check permissible fieldbus length and number of spurs

Basic current Is there a basic current of min. 11 mA?
Bus address Check bus address: make sure there are no double assignments
Bus termination
(Termination) Is the FOUNDATION Fieldbus-H1 network correctly terminated?
Each bus segment must always be terminated with a bus terminator at both ends (start and
finish). Otherwise there may be interference in data transmission.
Current consumption,
permissible feed current Check the current consumption of the bus segment:
The current consumption of the bus segment in question (= total of basic currents of all bus
users) must not exceed the max. permissible feed current of the bus power supply.
Device Description (DD) Install the DD if you cannot access the manufacturer-specific parameters.
