Method of operation and functions
The AED digital transducer electronics (acronym from the German: AufnehmerElek
tronikDigital) digitally condition the signals from SG
1)
transducers and offer different
interfaces, depending on the version. This way, you can connect SG transducers to a PC
or PLC in a full bridge circuit and create complete measurement chains at little expense.
The basic AED device accommodates the AD103C amplifier board, which digitizes and
processes the signal from the transducer. It provides:
S
Mechanical protection (IP65)
S
The power supply for the amplifier board and transducer excitation voltage
S
Bridge excitation voltage for SG transducers with a total bridge resistance of 80 …
4000 Ω or 40 … 4000 Ω (AED9101D only)
S
An EMC-tested combination of basic device and AD103C amplifier board
S
A diagnostic bus

Depending on the version, serial interfaces RS‐422, RS‐485 or RS‐232 or industrial
bus systems CANopen

Important
The AD103C amplifier board is not included in the scope of supply of the basic device,
and must be ordered separately.
The digital inputs and outputs enable you to do the following:
S
Control processes using limit values (
LIV …)
S
Start measurements via triggers (
MAV)
S
Control a filling or dosing process.
Different numbers of inputs and outputs are available, depending on the version.
The PanelX PC software is available to facilitate parameter settings, display dynamic
measurement signals and for comprehensive system analysis. You can download the
