The PCIe-DIO-48JPS 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 chips 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. The card is 6.6 inches in length and 4.2 inches seated height.
Two 24 line groups each have three 8-bit I/O ports designated A, B and C. Port C can be further divided into two 4-bit nybbles. 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.
This card is an excellent choice for system designs that would benefit from using a wiring harness to connect up to a complete system. This is due to the 68-pin I/O connector being located on the card mounting bracket, it is a much cleaner card solution to use compared to routing ribbon cables through a cutout on the card mounting bracket, then plugging them onto the headers on the side of the card.
The PCIe-DIO-48JPLS 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-48JPLS 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
Available accessories include ribbon cables and shielded round-wire molded cable assemblies. Screw terminal boards and DIN-rail mounts are also available for a variety of quick and easy connectivity options.
The card is supported for use in most operating systems and includes a free Linux and Windows 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. Embedded OS support includes the family of Windows Operating Systems including IoT. ACCES is also now offering a VxWorks driver/library for the ultimate real-time process monitoring and control solution.
