PCI Express 48 Channel Digital I/O Card PCIe-DIO-48
Features 48 or 24 channel high-current TTL digital I/O lines Change of State (COS) detection and interrupt capabilities Compatible with industry standard 8255 PPI Two 50-pin male headers with 24 digital lines each User interrupt pin on each DIO connector All 48 digital I/O lines buffered with 32mA source / 64mA sink current capabilities Four and eight bit ports independently selectable for inputs or outputs Pull-ups on DIO lines (optional pull-down) 5V VCCIO (3.3V optional) VCCIO available to the user on each I/O header Compatible with industry standard I/O racks like Grayhill, Opto 22, Western Reserve Controls, etc. Easy upgrade from PCI-DIO-48S FACTORY OPTIONS 3.3V VCCIO (LVTTL) Molex PC-style connector for maximum 5V VCCIO current sourcing capability RoHS compliant version Extended temperature operation (-40°C to +85°C) The PCIe-DIO-48S is a 48 channel PCI Express (PCIe) card designed for use in a variety of digital I/O applications. It uses the high speed PCI Express bus to transfer digital data to and from the card. The digital I/O is compatible with 8255 PPI (mode 0), making it easy to program. This also allows for simple and trouble-free migration from other ACCES PCI digital I/O cards. The card features a x1 lane PCI Express connector which can be used in any available x1, x2, x4, x8, x12, or x16 PCI Express expansion slot. Each 50-pin header has three 8-bit I/O ports designated A, B and C. Port C can be further divided into two 4-bit nibbles. Each port can be programmed as inputs or outputs. Change of State (COS) detection and interrupt capabilities are designed to relieve software from polling routines that can consume valuable processing time. Each port can be programmed for detecting state changes on their lines, in which any changes of the enabled port's bits (low-to-high or high-to-low) will generate an IRQ. An ISR (interrupt service routine) then polls the port to determine which bit changed state and clear the interrupt. The connectors are also compatible with existing 48 and 24 channel ACCES PCI digital I/O cards. The card is 6.6 inches in length and 4.2 inches seated height. One or two flat ribbon cables are routed through a cutout in the mounting bracket and plugged onto the keyed 50-pin male headers on the side of the card. A strain relief bracket securely holds the ribbon cables at the point of exit via the PCIe mounting bracket. Applications The PCIe-DIO-48S 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-DIO-48S Series can be used in the following markets. Process Monitoring Manufacturing/Produc tion Test Machine Control Monitoring and Control Security Systems, Energy Management Industrial Automation Factory Automation Laboratory Automation Embedded OEM Accessories Available accessories include a broad range of ribbon cables, screw terminal boards and optically isolated adapters and DIN-rail mounts for a variety of quick and easy connectivity options. Use ribbon cables with a female header on one end and a 50-pin female edge connector on the other to connect with industry standard solid state module racks. SOFTWARE The card is supported for use in most operating systems and includes a free DOS, Linux, and Windows XP/2003/2008/7/8/8.1 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, etc.
