AED9301B HBM
2 Mechanical construction
The basic device extends the functionality of the AD amplifier boards and provides:
 mechanical protection (IP65)
 a slot for the AD103C amplifier board
 the power supply for the amplifier motherboard and transducer excitation (electrically iso-
lated)
 total transducer bridge resistance 80 ...4000 
 a Profibus DP interface (electrically isolated from the amplifier and from the digital inputs
/outputs)
 digital inputs/outputs (electrically isolated from the amplifier and from the Profibus)
 EMC protection
 Diagnostic bus
The amplifier motherboard (AD103C) is designed as a plug-in board that can be plugged into
the carrier board of the basic device via a 25-pin sub-D connector. The basic device contains
terminals for the transducer, power pack, digital inputs/outputs and Profibus connections,
slide switches for bus disconnection and termination resistor connection and the voltage sta-
bilizer. The connection cables exit the casing via PG glands on the side.
