Optional OMB-AI-EXP32 expansion module

Use the OMB-AI-EXP32 (sold separately) for applications that need additional analog/thermocouple input and digital I/O channels. See the Omega Engineering web site for product details.

The OMB-AI-EXP32 expansion port is intended to interface with a OMB-DAQ-2416 series product. Do not try to use any of the expansion port pins for any other purpose.
