DIAMOND-MM-32-AT PC/104 16-Bit Analog I/O Module with Autocalibration
1. DESCRIPTION
Diamond-MM-32-AT is a PC/104-format data acquisition board with a full set of features. It offers 32 total
analog inputs with 16-bit resolution and programmable input range; 200,000 samples per second
maximum sampling rate with FIFO operation; 4 analog outputs with 12-bit resolution; user-adjustable
analog output ranges; 31 lines of digital I/O; one 32-bit counter/timer for A/D conversion and interrupt
timing; and one 16-bit counter/timer for general purpose use. Diamond-MM-32-AT offers the additional
important feature of autocalibration for both analog input and output channels.
