SCMA150 is a very affordable fast easy-to-program 8-Bit data acquisition board.

SCMA150/1
8 Channel A/D ( 8 bits, 400 Khz ) Data Acquisition Boards

The SCMA150 is a very affordable fast easy-to-program 8-Bit data acquisition board. It features eight single ended analog 0 to 5 volt inputs and does each channel conversion in only 2.5 microseconds. Each conversion is started automatically with a read of the last converted result, making programming very simple. The SCMA150 also has a 10 MHz oscillator with an 82C54 (3 16-bit down counters) that can be programmed for a variety of functions, such as square wave oscillators, counting operations, accurate time base, etc. Counter chaining is also possible via the on-board jumper settings, providing either 32-bit or 48-bit down counters.

A fully buffered Interrupt Level jumper block with IRQ2 through IRQ7 selection is also provided on the ANA151 / SCMA150 Analog Board.
