Analog I/O configuration
Analog inputs (AI’s)
The basic I/O board is the SDCS-CON-F with 4 standard AI’s. Extend them by means of one RAIO-01 analog
I/O extension module. Thus, the maximum number of AI’s is 6.
Select the hardware source by:
−
AIO ExtModule (98.06) for AI5 and AI6
SDCS-CON-F
Hardware setting:
−
switching from voltage input to current input by means of jumper S2 and S3
Input range AI1 and AI2 set by parameter:
− ±
10 V, 0 V to 10 V, 2 V to 10 V, 5 V offset, 6 V offset
− ±
20 mA, 0 mA to 20 mA, 4 mA to 20 mA, 10 mA offset, 12 mA offset
Input range AI3 and AI4 set by parameter:
− ±
10 V, 0 V to 10 V, 2 V to 10 V, 5 V offset, 6 V offset
Resolution:
−
15 bits + sign
Scan time for AI1 and AI2:
−
3.3 ms / 2.77 ms (synchronized with mains frequency)
Scan time for AI3 and AI4:
−
5 ms
RAIO-01
Hardware setting:
−
input range and switching from voltage to current by means of a DIP switch, for more details see RAIO-01
User’s Manual
Input range AI5 and AI6 set by parameter:
− ±
10 V, 0 V to 10 V, 2 V to 10 V, 5 V offset, 6 V offset
− ±
20 mA, 0 mA to 20 mA, 4 mA to 20 mA, 10 mA offset, 12 mA offset
Resolution:
−
11 bits + sign
Scan time for AI5 and AI6:
−
10 ms
Additional functions:
−
all AI’s are galvanically isolated
Configuration
The value of AI1 to AI6 and AITacho can be read from group 5.
AI configurable default setting
1 yes -
2 yes -
3 yes -
4 yes -
5 yes -
6 yes -
Configurable = yes:
−
The AI’s can be connected to several converter functions and it is possible to scale them by means of
group 13. In addition the AI’s can be read by AP or overriding control.
