Voltage Conversion Units - Automation Direct DL405 User Manual

For unipolar thermocouple ranges (R,S,B,C), it does not matter if magnitude plus
sign or 2's complement is selected.
Use the table to select settings. The module comes with both jumpers installed for
magnitude plus sign conversion in Fahrenheit. For example, remove the Units-0
jumper and leave the Units-1 jumper installed for magnitude plus sign conversion in
Celsius.
X = Jumper installed, and blank space = jumper removed.
The bipolar voltage input ranges, 5V or 156mV (see previous page for 5V
Voltage
and 156mV settings), may be converted to a 15-bit magnitude plus sign or a
Conversion
16-bit 2's complement value.
