PP8AIVS - 8 Voltage Input Module Fully Isolated

The PP8AIVS module is an 8 channel isolated voltage input module. The module uses differential inputs to reduce effects of electrical noise and mains pickup. The voltage inputs are isolated from the logic and from each other. 

The voltage input can be represented in a number of formats according to the type which is setup by writing a value to the Type register. The value is obtained from the table below. 


The standard setting for the PP8AIVS module is 0 – 10.000V input voltage which represents an output value of 0 - 4095 (12 bits).  2V would give a reading of 819 ± 1LSB. 

The module can also be configured for a +/- 10.000V input.  The module also supports 16 bit ranges.
