3.6 Daughter Board Connection
The ACL-8112 can be connected with any of the five following daughter
boards, ACLD-8125, ACLD-9137, ACLD9182, ACLD9185, and ACLD9188.
The functionality and connections are specified below.
3.6.1 Connect with ACLD-8125
The ACLD-8125 has a 37-pin D-sub connector, which can be connected to
the ACL-8112HG through a 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 thermo-coupler to the ACL-
8125 board.
3.6.2 Connect with ACLD-9137
The ACLD-9137 is a direct connector for the ACL-8112 card which is
equipped with a 37-pin D-sub connector. This board provides a simple way
for connecting simple applications that do not need complex signal
conditioning before an A/D conversion is performed.
3.6.3 Connect with ACLD-9182
The ACLD-9182 is a 16 channel isolated digital input board. This board is
connected to CN1 of the ACL-8112 via a 20-pin ribbon cable. The
advantage of this board is the 500Vdc isolation voltage that it provides,
thus it can protect your PC system from damage when an abnormal input
signal occurs.
3.6.4 Connect with ACLD-9185
The ACLD-9185 is a 16 channel SPDT relay output board. This board is
connected to CN2 of the ACL-8112 via a 20-pin ribbon cable. By using this
board, you can control external devices through digital output signals.
3.6.5 Connect with ACLD-9188
The ACLD-9188 is a general purpose terminal board for all cards which
comes equipped with a 37-pin D-sub connector.
