Data acquisition PCCMCIA card (24-Bit) : AD142

24-bit 16-Channel, 8-DIO ADC DAQ PC Card - AD218

The AD218 uses a 24-bit Sigma Delta A-to-D converter to produce very high resolution measurements, typically up to 21 effective bits when sampling at 50 or 60Sample/sec.  The card consumes very little power and so is ideal for portable instrumentation.

Technical Features

Chip 24-bit Sigma Delta A-to-D converter, optimized for sample rates of less than a few hundred samples per second.  Max sample rate is 1KSample/sec at reduced resolution
Chip 16-channel fault protect input mux switchable between single ended and differential topology
Chip Input ranges are software configurable from +2.5V/-2.0V down to +/-19.5mV in bipolar mode, or from 2.5V to 19.5mV in unipolar mode
Chip Power is available at the edge connector for signal conditioning, powering sensors etc
Chip Built in 16-bit counter with clock and gate inputs for event monitoring
Chip 8 general purpose digital I/O lines are available for control and status monitoring, each being programmable as input or output and having TTL compatible input thresholds, and CMOS type output drive capability
Software Card comes with Elan's Card Center Pro software with kernel driver and data handling module, plus a top level Win32 GUI with source code to act as a starting point for your own development.  Full hardware register data is provided to allow exact tailoring for bespoke applications
Software Drivers for DOS, Win9x, Me, NT4, 2000, XP
Software Automatic O.S. recognition and configuration.  Hot swappable PCMCIA 2.1+ compliant TypeII design
Power consumption Power consumption: Typical 20mA at 5V fully active
Electrostatic discharge Input mux channels can withstand voltages up to +/-35V with the card powered or +/-25V if not powered
Cable options Supplied with 1m Type30 cable.  Connector latches into PC Card for security. Terminates to DB37 Female with male screw jacks.  Custom cabling available on request to set different gains and / or to offer dual coax to BNC connection or similar for connection to accelerometers
Cable options Can be fitted with Elan's unique Strain Relief Assembly to ruggedize the PC Card to cable connection (optional extra), product code "SRA1"

*DOS support requires Card and Socket Services e.g. SystemSoft or Award
