10.4.2 Analog input module AI 8 x 16 Bit
Article numbers
Standard module: 6ES7 650-8AK60-0AA0
Module with conformal coating: 6ES7 650-8AK60-1AA0
Properties
The analog input module AI 8 x 16 Bit is characterized by the following properties:
● 8 inputs and 8 outputs (for supplying of 2-wire transducers)
● HART conforming
In non-redundant operation, connection of a resistance of approximately 100 in series with
the transducer is recommended.
● Resolution of 15 bits + sign (regardless of integration time)
● Setting of the transducer for each module (via a jumper at terminals 10 and 11):
– 2-wire transducer current, only in measuring range 4 ... 20 mA
– 4-wire transducer current
● Configurable measuring range for each channel
– 0 ... 20 mA
– ± 20 mA
– 4 ... 20 mA
● Configurable smoothing for each channel
● Configurable integration time/interference frequency suppression for each channel
● Configurable diagnostics
● Configurable diagnostic interrupt
● Electrical isolation
– Channels electrically isolated for 4-wire transducer to load voltage L+
– Channels electrically isolated from IM 650
● Group error display (SF LED)
● Configuration in Run (CiR) supported
Wiring and block diagrams of the AI 8 x 16 Bit with 2-wire transducer operation
If the module is used for 2-wire transducer operation, a jumper must be inserted between
terminals 10 and 11. This activates the short-circuit-protected transducer supply of the module
and implements the jumpering at the analog input.
All channels of the module operate in 2-wire transducer mode in this case. This is shown in the
figure below using channel 0 as an example.
The parameter assignment is made via HW Config as “2WMT current”
