Description

VMIVME1181-000: Product Overview​
The GE VMIVME1181-000​ is a digital I/O board designed for integration into VMEbus-based industrial automation systems. As a critical component of the VME ecosystem, it enables reliable signal transmission between field devices (e.g., limit switches, solenoid valves, contactors) and the main controller, supporting real-time control and monitoring in harsh industrial environments.
Role in Automation Systems:
Positioned as a “field interface” in VMEbus architectures, the VMIVME1181-000 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 relay outputs.
Core Functionality:
  • VMEbus Compatibility: Conforms to the VME64 standard, ensuring seamless integration with VMEbus-based controllers (e.g., GE Fanuc 90-30 series) and backplanes.
  • Flexible Signal Configuration: Uses hardware jumpers to select signal types (dry contact, 24–230 V AC/DC) and configure input/output modes (e.g., normally open/normally closed).
  • Optocoupler Isolation: Provides 1500 V AC channel-to-channel isolation, protecting sensitive controller circuits from voltage spikes and noise in industrial environments.
  • Status Indication: Equipped with LED indicators for power status, input/output activity, and fault conditions, simplifying troubleshooting and maintenance.
Platform Benefits (VMEbus Series):
The VMIVME1181-000 leverages GE’s VMEbus platform, which is renowned for:
  • Reliability: Industrial-grade components and a rugged design ensure 24/7 operation in harsh environments (e.g., high temperature, vibration).
  • Scalability: Supports expansion with additional I/O boards to accommodate growing system demands (e.g., adding more sensors or actuators).
  • Integration: Seamlessly integrates with VMEbus-based controllers and other I/O modules, reducing setup time and effort.

Core Features & Customer Value​
1. Reliable Digital Signal Transmission:
The VMIVME1181-000’s optocoupler isolation and VMEbus compatibility ensure accurate signal transmission from field devices to the main controller, even in electrically noisy environments. For example, in a manufacturing plant, the board can reliably monitor the status of a conveyor belt’s limit switch, ensuring that parts are delivered to the assembly line in time.
2. Flexible Configuration:
Hardware jumpers allow engineers to customize the board’s functionality without software changes. For instance, configuring the input signal type (dry contact vs. 24 V DC) via jumpers enables the board to interface with different types of sensors, saving time and money during installation.
3. Rugged Industrial Design:
The board’s operating temperature range (-40°C to +85°C) and compact form factor make it suitable for harsh industrial environments. Its DIN rail mounting option simplifies installation in crowded control cabinets, reducing setup time and effort.
4. Easy Troubleshooting:
LED indicators for power status, input/output activity, and fault conditions allow operators to quickly identify and resolve issues. This reduces downtime and improves system reliability, which is critical for industrial facilities where unplanned outages can result in significant financial losses.
