Description

VMIVME-2528: Product Overview​
The GE VMIVME-2528​ is a 128-bit digital I/O board designed for VMEbus-based industrial automation systems. As a critical component of the VME ecosystem, it enables reliable digital signal transmission between field devices (e.g., limit switches, proximity sensors) and the main controller, supporting real-time control and monitoring in harsh industrial environments.
Role in Automation Systems:
Positioned as a “field signal interface” in VMEbus architectures, the VMIVME-2528 performs two primary functions:
  1. Digital Input Acquisition: Receives digital signals from field devices (e.g., a limit switch indicating a valve is open) and transmits them to the main controller for processing.
  2. Digital Output Control: Sends control commands from the main controller to field actuators (e.g., starting a pump, opening a valve) via digital outputs.
Core Functionality:
  • 128-Bit I/O Capacity: Supports 128 digital channels (configurable as input or output), accommodating large numbers of field devices in industrial systems.
  • TTL Compatibility: Uses TTL (Transistor-Transistor Logic) signaling, ensuring compatibility with most industrial sensors and actuators.
  • VMEbus Integration: Conforms to VMEbus Rev. C.1, enabling seamless integration with VME64 backplanes and controllers (e.g., GE Fanuc 90-30 series).
  • Rugged Design: Industrial-grade components and a compact form factor make it suitable for harsh environments (e.g., high temperature, vibration).

Core Features & Customer Value​
1. High-Density I/O Capacity:
The VMIVME-2528’s 128-bit I/O capacity reduces the number of boards needed in a system, saving space and cost. For example, in a power plant, the board can handle all digital signals from turbine sensors (e.g., blade position, valve status) with a single module.
2. Reliable Signal Transmission:
TTL compatibility and VMEbus integration ensure accurate signal transmission, even in electrically noisy environments. This reliability is critical for maintaining turbine stability and preventing unplanned outages.
3. Rugged Industrial Design:
The board’s operating temperature range (0°C to +55°C) and compact form factor make it suitable for harsh industrial environments. Its DIN rail mounting option simplifies installation in crowded control cabinets.
4. Easy Integration:
VMEbus compatibility allows seamless integration with existing VMEbus systems, minimizing downtime and effort during upgrades. This is invaluable for facilities with legacy VMEbus installations.
