IC200ALG321
Analog Output Module, 12 Bit Voltage 0 to 10VDC 4 Channels
Scaling
The graphs below show the relationship between the output voltage measured at the field
terminals and the data that is output by the module.

Voltage can be calculated using the following equation:
Vout = ( (analog counts x 10.25) / 32768 )
The count value must be a multiple of 8. If the module receives a count value that is not a
multiple of 8, it rounds the value down to the closest multiple of 8. For example:
Count Voltage
16024 5.0125V
16030 5.0125V
16032 5.0150V
