New I/O Extension Module From Wixom's Acromag

WIXOM -- Acromag Corp. Monday introduced its new model AXM-75, a multi-function input-output extension module that multiple signal processing functions to a FPGA (field-programmable) processor board.

Acromag's extension I/O modules plug directly onto PMC and XMC reconfigurable FPGA cards equipped with an AXM mezzanine connector.

Using the AXM-A75, engineers can interface a number of high-level analog voltage signals to and from the FPGA. TTL-level digital I/O channels can monitor and control discrete devices. A 68-pin VHDCI receptacle provides easy field I/O connections. The operating range is minus 40 to 85 degrees C (minus 40 to 180 degrees Fahnrenheit). Typical uses include hardware simulation, in-circuit diagnostics, machine control, signal intelligence, and image processing.

List price is $1,700.

There are sixteen differential analog input channels on the AXM-A75. Each input has its own high-speed 16-bit 250kHz A/D converter offering the ability to simultaneously sample all channels. A low-pass filter removes unwanted EMI. The input range is +/-10 volts with programmable gain of 1x, 2x, 4x, or 8x. Serial FLASH memory stores the factory calibration constants.

Two quad DAC devices drive eight analog output channels with a range of +/- 10V. Each channel has its own high-speed 16-bit D/A converter which allows updating of individual channels or all outputs simultaneously. The D/A settling time is 10microS.

Sixteen bi-directional digital I/O channels provide the ability to read or write 5V logic levels on TTL devices. Each I/O channel is individually configurable as an input or output for great flexibility to match your requirements. The open drain outputs are pulled high via a pull-up resistor.

Acromag has designed and manufactured measurement and control products for more than 50 years. Acromag offers a complete line of embedded I/O and industrial computer products for military, aerospace, manufacturing, transportation, utilities, and scientific research applications.
