Diamond-MM has all the primary features you expect in a high-performance analog I/O board at a reduced price. The analog input circuit uses a 12-bit A/D converte and can be configured for single-ended or differential input wiring, as well as unipolar or bipolar input ranges. It also offers 10 different input ranges, so it can work with a wide variety of input signals. The maximum A/D conversion rate is approximately 2,000-20,000 per second using interrupts (depending on the operating system) or 100,000 per second using DMA.
Two optional analog outputs provide 12-bit resolution over a 0-5V or user-adjustable output range with 8mA drive current and 4uS settling time. The D/A can also be used as a digital attenuator for an analog signal fed into one of the reference inputs.
The board contains 8 digital inputs and 8 digital outputs. It has an on-board 82C54 counter/timer chip to control the A/D sampling rate and provide general purpose counting functions.
Diamond-MM is available in four models: with or without analog outputs, and in commercial (0ºC-70ºC) or industrial (-40ºC to +85ºC) operating temperature range.
