* For compensation of the reference junction temperature for thermocouples. BU type A1 is required if
you measure the reference junction temperature with an internal temperature sensor or if you need
the additional 2×5 terminals.
If you use the internal reference junction temperature with BU type A1, ensure an even tempera-
ture distribution at the terminals. The specified accuracy of the utilized analog module is then ad-
hered to. If necessary, you can increase the accuracy via user calibration.
** Analog mod
ules
with and without
temperature measurement can also be plugged into BU type A0.
