AI-EXP48
The AI-EXP48 expansion board can be used in combination with compatible parent boards, such as a USB-
1616HS Series board.
The AI-EXP48 supports all of the analog input and temperature input capabilities of the parent board, but
expands the channel count as follows:
Analog Input
Analog input argument values
HighChan 16 to 63 in single-ended mode, 8 to 31 in differential mode
Temperature Input
Temperature input argument values
HighChan 8 to 31
DAQ input
DAQ input argument values
ChanArray ANALOG: 0 to 63 in single-ended mode, 0 to 31 in differential mode
CJC: 6 to 11
TC: 8 to 31
Hardware considerations
Associating CJC channels with TC channels
The TC channels must immediately follow their associated CJC channels in the channel array. For accurate
thermocouple readings, associate CJC channels with the TC channels as listed in the following table:
CJC channels
TC channels
CJC6
TC8 through TC11
CJC7
TC12 through TC15
CJC8
TC16 through TC19
CJC9
TC20 through TC23
CJC10
TC24 through TC27
CJC11
TC28 through TC31
The parent board must be configured for differential inputs when using thermocouples
TC inputs are supported by differential mode configuration only.
