AD amplifier boards are designed as plug-in boards and plug into the carrier board via a
25-pin sub-D connector.
The use of an AED basic device (not supplied with the AD103C) adds the following char
acteristics to extend the functionality:
S
Mechanical protection (IP65) via AED9101D, AED9201B, AED9301B, AED9401A or
AED9501A basic devices
S
Overall bridge resistance (40) 80...4000
Ω
via the power supply to the basic devices
S
Additional interfaces RS232, RS422/RS485, Profibus, CAN bus, DeviceNet
S
Electrically isolated digital inputs/outputs
S
EMC protection (tested)
S
Cover for the ‘write protection’ switch and stamping point for LFT applications
S
Diagnostic bus
The basic device features terminals for the transducer, power supply and PC connec
tions, switches for interface selection, and the voltage stabilizer. The connection cables
exit the housing via PG glands (see the respective operating manuals, Basic devices):
AED9101D basic device
RS232/RS485 2- or 4-wire interface
AED9201B basic device
RS232/RS485 4-wire interface
AED9301B basic device
Profibus interface
AED9401A basic device
CANOpen or DeviceNet interface
AED9501A basic device
CANOpen or DeviceNet interface
The basic devices still differ in the following functionality:
AED9101D basic device
Supports the input IN1
AED9201B basic device
Supports the inputs IN1, IN2 and OUT1...6
AED9301B and AED9401A basic devices
Support the inputs IN1, IN2 and OUT1...4
AED9501A basic device
Supports the input IN1
The AED9201B, AED9301B and AED9401A basic devices achieve complete electrical
isolation of the amplifier from the power supply, the serial interface and the digital
inputs/outputs.
All basic devices support the diagnostic bus.
