NT-1751-AE

48-Channel Digital I/O & 3-Channel Counter PCI Express Card

The PCIE-1751-AE is a versatile 48-bit digital I/O PCI Express card featuring flexible port configuration and integrated 32-bit counters. Designed for industrial systems, it offers reliable performance with advanced interrupt and filtering capabilities.

Product Description:

The PCIE-1751-AE is a 48-channel TTL digital I/O card for the PCI Express bus. The channels are divided into six 8-bit ports, with each 4-bit nibble configurable as input or output via software.

The card emulates Mode 0 of the 8255 PPI, ensuring compatibility with legacy systems. It also includes three 32-bit counters with timer/counter interrupt capability, making it suitable for event counting, frequency measurement, and timing applications.

With programmable digital filters and change-of-state interrupts, the PCIE-1751-AE ensures accurate and responsive digital signal monitoring.

Product Features:

48 TTL digital I/O lines
Six 8-bit I/O ports (configurable per 4-bit nibble)
3 × 32-bit counters
Change-of-state interrupt function for DI
Pattern match interrupt function for DI
Programmable digital filter for DI
Timer/Counter interrupt capability
Buffered circuits for higher driving capacity
Retains I/O port settings and DO states after system reset
BoardID switch for easy identification

Performance & Reliability:

The nibble-based configuration provides flexible control for mixed input/output applications. Buffered output circuits offer higher driving capacity compared to standard 8255 designs.

Change-of-state and pattern-match interrupts enhance responsiveness in event-driven systems, while digital filtering improves signal reliability in noisy environments.

System Architecture:

The PCI Express interface ensures high-speed data transfer and seamless integration into modern industrial PCs.

The three 32-bit counters enable advanced timing, pulse counting, and frequency measurement tasks, making the card suitable for a wide range of automation and control applications.

Applications:

Industrial Automation Control
Event Monitoring Systems
Machine Control & Diagnostics
Pulse & Frequency Measurement
Factory Process Monitoring
Legacy 8255 System Replacement
