ISO-RACK16/P CONNECTION DIAGRAM
The ISO-RACK16/P series allows analog inputs for the CIO-DAS6400 and PCI-DAS6400/1600/1200/1000 series of A/D boards to be quickly and simply
connected to ISO-5B series isolation and signal conditioning modules. The ISO-RACK16/P map a single analog input channel to a single ISO-5B module(A/Dchannel 0 is directly connected to module 1, channel 1 to module 2 etc).

P23P24P22P21CONNECTOR PIN ASSIGNMENTSPins 35-50 of connectors P22, P23, and P24 have been wired 1:1 to provide access to some of the host A/D’s boards
signals (see CONNECTOR MAP diagram for details). These signals are labeled “PASS” signals and the user should
consult their DAS manual’s I/O connector pin assignment section to verify the actual signals which are available.
NOTES:1.) The board provides locations to install jumpers that allow the analog inputs from the controlling board to be
directly connected to the output screw terminals. This allows hybrid systems in which analog inputs requiring
isolation and/or signal conditioning to use the ISO-5B modules while other analog inputs can be connected directly tothe host A/D board. A series of plated through jumper holes labeled Rx+ and Rx- jumper the analog inputs of thehost A/D board directly to the screw terminals.
2.) A CJC reference sensor is provided with ISO-5B thermocouple modules and must be installed in the appropriate
U1-U16 position.

External power can be provided toMolex connector P21 from the PC
power expansion plug inside the PC.
Screw terminal P20 could also be used
to provide external power.

Typical Channel

3.) Shunt resistor positions R1-R16 allow each analog input channel to convert a current to a voltage.
4.) Connector P22 “16 CHANNEL IN” allows the ISO-RACK16/P to interface directly to 16 channel A/D boards utilizing
100 pin I/O connectors (see Connection Diagram for details). Connector P23 and P24 “64 CHANNEL IN/OUT” allows
multiple ISO-RACK16/P boards to be daisy chained providing a direct connection to 64 channel A/D boards utilizing 100pin I/O connectors (see Connection Diagram for details).
