2.8Daughter Board Connection

The PCI-9111 can be connected with five different daughter boards, ACLD-8125, ACLD-9137, 9138, 9182, 9185, and 9188. The functionality and connections are specified as follows.

2.8.1Connect with ACLD-8125

The ACLD-8125 has a 37 -pin D-sub connector, which can connect with PCI-9111 through 37-pin assemble cable. The most outstanding feature of this daughter board is a CJC (cold junction compensation) circuit on board. You can directly connect the thermocouple on the ACL-8125 board. The CJC only suitable for High Gain version board.

2.8.2Connect with ACLD-9137

The ACLD-9137 is a direct connector for all the cards which equipped with 37-pin D-sub connector. This board provides a simple way for connection. It is very suitable for the simple applications that do not need complex signal condition before the A/D conversion is performed.

2.8.3Connect with ACLD-9182

The ACLD-9182 is a 16 channel isolated digital input board. This board is connected with CN1 of PCI-9111 via 20-pin flat cable. The advantage of board is an 500Vdc isolation voltage is provided, and it can protect your PC system from damage when an abnormal input signal is occurred.

2.8.4Connect with ACLD-9185

The ACLD-9185 is a 16 channels SPDT relay output board. This board is connected with CN2 of PCI-9111 via 20-pin flat cable. By using this board, you can control outside device through the digital output signals.

2.8.5Connect with ACLD-9138 and ACLD-9188

ACLD-9138 and ACLD-9188 are general purpose terminal boards for all the cards which come equipped with 37-pin D-sub connector. The ACLD-9138 has a LED indicator to show the power ON/OFF of your computer system.
