 Technical Reference & Availability: General Standards Corp PCIE-DIO24A-ISA 24-Channel Digital I/O Board

The PCIE-DIO24A-ISA from General Standards Corporation (GSC) is a high-reliability, 24-channel digital I/O interface designed to provide modern PCI Express (PCIe) systems with the industry-standard functionality of the 82C55 chip. This board is an ideal solution for migrating legacy ISA-based industrial controls to contemporary PC architectures without losing the direct software compatibility and robust logic characteristics of the 82C55 architecture.

Core Hardware Specifications

  • Manufacturer: General Standards Corporation (GSC)

  • Model: PCIE-DIO24A-ISA

  • I/O Architecture: Based on the industry-standard 82C55 programmable peripheral interface.

  • Channel Density: 24 Digital I/O channels.

  • Port Configuration: > * Two 8-bit ports (Port A and Port B).

    • One 8-bit port (Port C), further divisible into two 4-bit nibbles (Port C-HI and Port C-LO).

  • Logic Type: CMOS outputs, directly connected to the I/O connector, ideal for driving a wide range of logic-level devices.

Key Features for Industrial & Military Testing

  • Direct Pin-to-Pin Interface: The 82C55 I/O pins are directly mapped to the board's I/O connector for minimal latency and direct signal control.

  • Legacy Compatibility: Maintains the register-level behavior of traditional ISA 82C55 cards on a fast PCIe bus.

  • Versatile Logic Driving: Suitable for TTL/CMOS interfacing, relay control, and status monitoring in high-stakes environments.

Inventory & Global Logistics from Shenzhen
