Description
The AI-EXP32 is an expansion module used to double analog input count of either the USB-2416 or USB-2416-4AO multifunction measurement and control devices. It provides up to 32 single-ended/16 differential analog inputs with a 1 kS/s aggregate throughput. Each channel can be individually configured for single-ended or differential input. They offer nine software-selectable analog input ranges (±20 V, ±10 V, ±5 V, ±2.5 V, ±1.25 V, ±0.625 V, ±0.312 V, ±0.156 V, ±0.078 V).
The analog inputs can be configured as thermocouple inputs (up to 16 differential). In thermocouple mode, the AI-EXP32 includes built-in cold-junction compensation and open thermocouple detection. The AI-EXP32 also provides up to 16 additional digital I/O lines. Each digital I/O line can be used for either input or output.
Four banks of removable screw-terminal blocks provide connectivity to the analog input channels and digital I/O lines. The AI-EXP32 is connected to the USB-2416 or USB-2416-4AO module 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 modules to which it is connected. Power for AI-EXP32 comes from the USB-2416 series modules.
Hardware accessories included with every AI-EXP32:
A metal connection plate and four flathead screws are included for securing the two modules together when they are directly connected via the expansion connectors.
