The PMC-16AIO168 provides a cost effective, high-speed 16-bit analog input/ output and digital output board. Eight analog output channels (at 300,000 samples/ sec per channel) are updated either synchronously or asynchronously, and support arbitrary waveform generation. The analog inputs are configurable as either 16 single-ended or 8 differential input channels, and can be scanned continuously or in bursts. Four digital outputs are also offered (output only). Inputs and outputs have a common software selected range of ±10V, ±5V or ±2.5V, and are accessed through independent 32K-sample FIFO buffers. Internal auto-calibration networks permit calibration to be performed without removing the board from the system. Software controlled test configurations include a loop-back mode for monitoring all analog output channels.

Eight 16-Bit 0-20mA or 4-20mA scanned analog input channels, Software-configurable also as unipolar voltage inputs; 16 single-ended or eight differential, scaled as 0 to +10V, 0 to-+5V or 0 to +2.5V. Four 16-Bit current-loop output channels, configurable as 0-20mA or 4-20mA ranges, driven by four voltage-output DACs scaled as 0 to +10V, 0 to +5V or 0 to +2.5V. Both the current-loop outputs and the outputs of the voltage-DACs are available at the system I/O connector.

The PMC-16AO4MFS D/A board provides 400KHz-per-channel precision high speed 16-bit analog outputs, and supports arbitrary waveform generation. Four analog output channels are updated independently from an internal buffer, either at software-determined rates, or by an externally supplied clock. Flexible operating modes include continuous, periodic and triggered burst functions, as well as the seamless, dynamic concatenation of waveforms in real-time. Output ranges are supplied as ±10V, ±5V or ±2.5V. Internal auto calibration networks permit periodic calibration to be performed without removing the board or host from the system. This feature produces the optimum calibration situation, in which the board is calibrated in its actual operating environment.
