Electrical connections
5.2.3.1 Bus Connection
The fieldbus transmitter is suitable for connection to the ABB multibarrier, the segment coupler
(PROFIBUS PA design only) and special power supply units or a linking device (FOUNDATION
Fieldbus design only). As well as the bus connection (terminals 31 / 32) there is also a freely
configurable switching output (terminals 41 / 42) available.
