PCIe-IDIO Series

This product is a x1 lane PCIe isolated digital input and FET output board with Change of State (COS) detection capabilities. In addition to the isolated signals, 8 (or 4) TTL/CMOS input/output pins are available, for your application’s convenience.

The isolated inputs can be driven by either AC or DC and are not polarity sensitive. Input signals are rectified by a diode bridge and applied to the inputs of opto-isolators. A 1.8k ohm resistor in series provides current limiting. Standard 12/24 AC control transmitter outputs can be accepted as well as DC voltages. The input voltage range is 3V to 31VDC (or 40-10kHz RMS). To extend the input voltage range, you may connect external resistors in series. Inputs can be configured to generate an IRQ when the input changes from active-to-inactive, inactive-to-active, or both in groups of eight bits.

The PCIe-IDIO-24 features fully protected and isolated high side power MOSFET switch outputs which are de-energized at power-up to prevent an unintended control output signal. They are capable of switching customer supplied voltages of 5 to 34VDC, at up to 2A.

The card is 6.6 inches in length and 4.2 inches seated height. I/O wiring connections for this board are via a 78-pin D-sub connector. A molded round-wire “Y” cable is typically used to connect this card to termination panels with two 37-pin D-sub connectors.

Applications

The PCIe-IDIO Series is excellent for use in a multitude of applications requiring digital control or monitoring such as in test equipment, instrumentation, lab automation, and process control. The board is capable of monitoring electrical devices such as motor controllers, powered switches, dry contacts, thermostats, limit switches, push buttons etc.. The PCIe-IDIO Series can be used in the following markets.

• Process Monitoring
• Manufacturing/Production Test
• Machine Control
• Monitoring and Control
• Security Systems, Energy Management
• Industrial Automation
• Factory Automation
• Laboratory Automation
• Embedded OEM

Accessories and Connections

For the PCIe-IDIO Series, I/O is accessed via a 78 pin DB female connector on the mounting bracket of the card. A molded breakout cable (model CAB78-37/2) is optionally available that divides the 78 pins into two DB37F connectors. Also available is a kit (model STB-37/2 Kit) which includes the cable, two STB-37 screw terminal boards, and one-foot length of DIN-rail mountable SNAPTRACK to mount the screw terminal boards.

SOFTWARE

The card is supported for use in most operating systems and includes a free DOS, Linux, and Windows XP -> 10, both 32 & 64 bit compatible software package. This package contains sample programs and source code in Visual Basic, Delphi, and Visual C++ for Windows. Also provided is a graphical setup program in Windows. Linux support includes installation files and basic samples for programming from user level via an open source kernel driver. Third party support includes a Windows standard DLL interface usable from the most popular application programs, and includes LabVIEW 8.5+ VIs. Embedded OS support includes Windows Xpe, WES7, vxWorks, etc.
