The Diamond-MM-AT analog I/O module offers autocalibration, programmable gain, A/D FIFO, and extended temperature operation to mid-range 12-bit analog I/O users. All these features are added on top of our existing Diamond-MM architecture at the same price as the original board, to bring you an unbeatable combination of features at this price level.
The 16 12-bit analog input channels feature programmable gains of 1, 2, 4, and 8, as well as programmable unipolar/bipolar range, for a total of 9 different input ranges. Maximum sampling rate is 100KHz (total for all channels), and a new 512-sample FIFO enables the board to operate at full speed in Windows operating systems using interrupts. DMA is no longer required to attain full speed.
Diamond-MM-AT offers 9 different programmable input ranges, including both unipolar and bipolar modes. Single-ended / differential operation is selected with jumpers, as it is with all our analog I/O boards.
The board also has 2 12-bit analog outputs with multiple unipolar and bipolar output ranges. A new programmable output range feature lets you set the output range anywhere between 0V and 10V with 1mV precision in software.
Both analog inputs and outputs benefit from our unique multi-range autocalibration process. Multiple on-board precision references are used to calibrate the board in each range, thereby ensuring the highest degree of accuracy. The analog outputs are also fed back to the autocalibration circuit for precise output range calibration as well as user-programmable output ranges.
Counters and Digital I/O
The board also has an on-board counter/timer to control A/D sampling or rate generator functions, 8 digital inputs, and 8 digital outputs. New features enable you to generate hardware interrupts from the counter/timer as well as an external digital signal. And in keeping with our real-world-friendly design, Diamond-MM-AT requires only +5V power supply and operates over the full industrial temperature range of -40 to +85oC.
