Sixteen Channel, 12-Bit Analog Input Card

PCI-AI12-16, PCI-AI12-16A

Model PCI-AI12-16 is a multifunctional, high-speed, analog-to-digital converter board for use in PCI-Bus computers. It accepts up to 16 single-ended or 8 differential inputs. The board uses a low-noise, multilayer printed circuit board. Inputs are protected against overvoltage conditions up to ±35 volts and typically survive static discharges beyond 4000 volts. Conversions can be initiated in any one of three ways: (a) software command, (b) external start commands, or (c) on a timed basis using on-board programmable counters. Converted data may be transferred to the computer by one of two software selected methods: (a) polling for the end-of-conversion signal, or (b) by generating an Interrupt when the end-of-conversion signal occurs. Model PCI-AI12-16A has all of the foregoing plus includes a 2K Samples FIFO data buffer and a 2K words Point List FIFO buffer. Addition of these FIFO's permits background-task-based data acquisition, essential for moderate throughput in Windows. The Point List FIFO contains channel, sub-MUX channel, and voltage range for each analog-input channel (point). The data buffer contains A/D conversion results. When the data buffer becomes half full, an Interrupt can be generated to cause the data to be read into the computer. Input analog voltages are amplified by a programmable-gain amplifier. Eight voltage ranges are available: 0-10V, 0-5V, an offset voltage range of +1.25V to +3.75V and 1.25 to 6.25 unipolar and ±10V, ±5V, ±2.5V, and ±1.25V bipolar. Further, by placing jumpers on the board you can manually select a 4-20 mA current range. In that latter case, the current input is converted to a special analog voltage range that will yield full 12-bit resolution and there can be up to eight inputs. In applications that require mixed voltage and current inputs, jumpers are placed only on the channels that are to have current inputs. Up to 256 differential or single-ended analog inputs can be handled through use of external signal conditioner/sub-multiplexers (model AIM-16P). The output of each 16-input sub-multiplexer will connect to one of the A/D single-ended inputs. There are four ports for discrete TTL-level digital inputs or outputs. When used as outputs, each output line can drive up to 350 mA. Also, there is a 7-bit output register. The latter is intended for use to send address and gain-control commands to external signal conditioner/sub-multiplexers. However, if that expansion capability is not used, then these bits can be used as general-purpose digital outputs. When software enabled, the PCI-AI12-16 board has Interrupt capability. An IntA can be initiated by completion of A/D conversions. In Model PCI-AI12-16A, an Interrupt can be initiated when the FIFO data buffer is half full. The FIFO’s used on A models permit data acquisition without timing concerns. A +10VDC (±0.2V) reference voltage is developed from the A/D converter reference source. That reference voltage is available at the I/O connector for external use and can source up to 200 mA. The PCI-AI12-16(A) is supported for use in most operating systems and includes a DOS, Linux, and Windows 95/98/Me/NT/ 2000/2003/XP compatible software package. This contains sample programs and source code in "C" and Pascal for DOS, and Visual Basic, Delphi, C++ Builder, and Visual C++ for Windows. Also incorporated is a graphical setup program in Windows. Third party support includes a Windows standard dll interface usable from the most popular application programs, along with LabView .VI samples. Linux support consists of installation files and basic samples for programming from user level via an open source kernel driver.
