2.8 Daughter Board Connection
The PCI-9111 can be connected with five different daughter boards. The
following are compatible: ACLD-8125, 9137, 9138, 9182, 9185, and 9188. The
functionality and connections are specified in the following sections
2.8.1 Connect with ACLD-8125
The ACLD-8125 has a 37-pin D-sub connector, which can connect to the
PCI-9111 through the 37-pin assemble cable. The most outstanding feature of
this daughter board is the CJC (cold junction compensation) circuit on board.
You can directly connect a thermocouple to the ACL-8125 board. The CJC is
only suitable for High Gain version boards
2.8.2 Connect with ACLD-9137
The ACLD-9137 is directly connected to the cards’ 37-pin D-sub connector. It
is suitable for simple applications that do not need complex signal conditioning
before an A/D conversion is performed.
2.8.3 Connect with ACLD-9182
The ACLD-9182 is a 16 channel isolated digital input board. This board is
connected to CN1 of the PCI-9111 via a 20-pin ribbon cable. The ACLD-9182
provides a 500Vdc isolation voltage protection, thus protecting your PC system
from damage in an event that abnormal input signals occur.
