The GBP 735 (OMB-DAQ-2416 and OMB-DAQ-2416-4AO) are multi-function measurement and control modules for the Universal Series Bus. The device has eight digital I/O lines and two counters with 24-bit analogue input devices for voltage or temperature. For its system expansion, doubling the number of analog input channels can be done by installing an additional OMB-AI-EXP32 which is just optional. The additional modules gives 16 more channels of DIO making the total DIO count of the mated pair be 24. The modules has its own impressive array of software including the new TracerDAQ®, a full-featured, out-of-the-box data logging for viewing, and analysis application.
