Multifunction Mezzanine Card conserves PMC slots.
Press Release Summary:
PMC730 module performs analog input, analog output, digital I/O, and counter/timer functions on one card. Multifunction PCI mezzanine card (PMC) plugs into PMC slots on VMEbus or CompactPCI(TM) CPU boards. Its 16-bit A/D converter with 512 sample RAM scans inputs in 10 microseconds per channel for 100 kHz throughput. Eight analog channels are provided with ±10 V signal range, and digital I/O tasks are accommodated with 16 TTL transceivers.
Original Press Release:
Acromag Introduces New Multipurpose PMC I/O Module That Performs Four I/O Functions To Save Card Slots
New PMC730 module conserves precious PMC slots on VMEbus and CompactPCI(TM) boards by performing analog input, analog output, digital I/O and counter/timer functions on a single card
Wixom, MI: Acromag's new PMC730 is a multifunction PCI mezzanine card (PMC) that combines the capabilities of four separate I/O modules on a single card that plugs into PMC slots on VMEbus or CompactPCI(TM) CPU boards. Since the PMC730 module performs analog input, analog output, digital I/O and counter/timer functions from a single slot, embedded computer designers can use fewer boards to handle more I/O functions which greatly reduces the cost of their systems. Typical uses include data acquisition, process control, and test & measurement. The standard model is priced at $1600 with extended temperature models ($1700) also available for operation from -40 to 85°C.
Analog input functions are handled by 16 differential or 32 single-ended input channels with four selectable unipolar and bipolar input ranges up to 10V DC. A 16-bit A/D converter with 512 sample RAM scans inputs in just 10 microS per channel for 100KHz throughput.
For analog output functions, eight channels are provided with a ±10V signal range. Each channel has a 16-bit D/A converter to deliver 80.8KHz processing speed with a 12.375 microS settling time. A 1024 sample FIFO buffer enables waveform generation functions.
Digital I/O tasks are accommodated with 16 TTL transceivers. The input/output direction is selectable on an 8-channel basis. Interrupt support and programmable debounce are included.
And, a 32-bit counter/timer is provided for a broad range of functions. Common applications include watchdog timer, event counting, pulse measurement, period measurement, and output waveform generation (pulse width modulation, continuous/single pulse, continuous waveform).
For easy integration of the PMC modules with Windows® 95/98/ME and NT/2000 applications, Acromag developed an ActiveX® (OLE) controls software package. ActiveX controls are object-based software components that function as drivers to interface the IP modules with compatible software development programs such as Microsoft' Visual C++(TM) and Visual Basic. ActiveX controls can also link I/O data to Human Machine Interface (HMI) process control applications, Microsoft Office® products such as Excel® and Access®, as well as many other desktop applications used to display and record data.
For connectivity with real time software application programs, Acromag offers C libraries for VxWorks® and other operating systems. The libraries provide generic routines (source code included) to handle reads, writes, interrupts, and other functions. Demonstration programs enable the developer to quickly exercise the I/O modules before attaching the routines to the application program. This diagnostic tool can save hours of troubleshooting and debugging.
The PMC mezzanine's modular format enables multiple functions and high-density I/O on a single board to lower costs and save card slots. With its rugged design, open architecture, and high performance, the PMC concept is ideal for a wide variety of I/O applications. Typical uses include data acquisition, process control, test & measurement, motion control, and network data communication.
Acromag, a multimillion dollar international corporation, has been manufacturing and developing instrumentation and control products for more than 40 years. They offer a complete line of industrial I/O products including VMEbus I/O boards, signal conditioners, wiring accessories, and software.
