Introducing the AI-EXP32
Overview: AI-EXP32 features
The AI-EXP32 is an expansion device you can use to add up to 32 single-ended analog inputs or 16 differential
analog/thermocouple inputs to compatible hardware, such as USB-2416 Series devices. Each input channel issoftware configurable for either voltage or thermocouple. The analog inputs are provided on four rows ofremovable screw terminals.
The voltage measurement speed is the same as the connected USB-2416 Series device. When measuring
thermocouples, configure the USB-2416 Series device for differential inputs.
The AI-EXP32 also provides up to 16 additional digital I/O channels. You can independently-configure eachchannel for either input or output.
Connect the AI-EXP32 to a USB-2416 Series device with the 37-pin expansion connector. The
AI-EXP32 supports all of the analog/thermocouple input and digital I/O features of the USB-2416 Series
device.
The AI-EXP32 is powered by the USB-2416 Series device.

Installing the AI-EXP32

Connecting to a USB-2416 Series device with the DSUB37 expansion
connector
Use the 37-pin expansion connector to connect the AI-EXP32 to a USB-2416 Series device.
To connect the two devices directly to each other, follow these steps.
1.

Disconnect the USB cable from the USB-2416 Series device.

2.

Remove the external power cable from the USB-2416 Series device.

3.

Connect the two devices together by inserting the AI-EXP32' DSUB37 connector into the DSUB37
connector on the USB-2416 Series device.

Figure 1. AI-EXP32 directly connected to a USB-2416-4AO

4.

Turn the connected devices over and secure the connection by screwing the connection plate to bothdevices, as shown below.

Figure 2. AI-EXP32 secured to a USB-2416-4AO

5.

Connect the external power supply to the power input port of the USB-2416 Series device, and then plug it
into an AC outlet.
By connecting external power to the device before connecting the USB cable to the computer, the USB2416- Series device informs the host computer upon connection of the USB cable that the device requires
minimum power from the computer's USB port.

6.

Connect the USB cable from the USB-2416 Series device to the host computer's USB port.

Connect to a USB 2.0 high speed hub to achieve the highest transfer rate (480 Mbps).
When connected to a USB 1.1 full-speed port, the transfer rate is limited to 12 Mbps.

Information on signal connections
General information regarding signal connection and configuration is available in the Guide to Signal
Connections (available at www.mccdaq.com/signals/signals.pdf).

Associating CJC channels with thermocouple channels
TC channels must immediately follow their associated CJC channels in the channel array. For accurate
thermocouple measurements, associate CJC channels with the TC channels as listed below.

Thermocouple
The AI-EXP32 GND and DGND pins are isolated from earth ground.
You can connect thermocouple sensors to voltages referenced to earth
ground as long as isolation between the GND/DGND pins and earth
ground is maintained.
Unused input channels can be left floating or tied to GND (pins 17, 18,
49, 50).
Voltage
When connecting differential voltage inputs to a floating voltage source,
the user must provide a DC return path from each voltage input toground. To do this, connect a resistor from each input to a GND pin (pins17, 18, 49, 50). A value of approximately 100 kΩ can be used for mostapplications.

Accuracy
Thermocouple measurement accuracy
The AI-EXP32 is a multiplexer-based channel expansion module that increases the number of thermocouple
input channels of a USB-2416 series host module. For thermocouple accuracy information, refer to theelectrical specification of the particular USB-2416 host module that is interfacing with the AI-EXP32.
There is a CJC sensor for each terminal block of the module. The thermocouple measurement accuracy assumes
that the screw terminals are at the same temperature as the CJC sensor.
Connect thermocouples to the AI-EXP32 such that they are floating with respect to GND (pins 17, 18, 49, 50).
When configuring thermocouple sensors, keep any stray capacitance relative to GND (pins 17, 18, 49, 50) as
small as possible to avoid settling time and accuracy errors.

Analog input DC voltage measurement accuracy:
The AI-EXP32 is a multiplexer-based channel expansion module that increases the number of voltage input
channels of a USB-2416 series host module. For voltage accuracy information, refer to the electrical
specification of the USB-2416 host device that is the interface to the AI-EXP32 interface.

Note 4: The external pull-up is connected to the digital output bit through an external pull-up resistor. Adding
an external pull-up resistor connects it in parallel with the internal 47k Ω pull-up resistor of thatparticular digital input/output bit. Careful consideration should be made when considering the external
pull-up resistor value and the resultant pull-up voltage produced at the load.
Note 5: Does not include the additional leakage current contribution that may occur when using an external
pull-up resistor.
