Description

VMIVME-2120: Product Overview​
The GE VMIVME-2120​ is a 64-bit high-voltage digital output board designed for VMEbus-based industrial automation systems. As a critical component of the VME ecosystem, it enables reliable digital signal output from the VMEbus controller to field actuators (e.g., solenoid valves, contactors, incandescent lamps) in applications requiring high current and voltage tolerance.
Role in Automation Systems:
Positioned as a “field actuator interface” in VMEbus architectures, the VMIVME-2120 performs two primary functions:
  1. Digital Signal Output: Converts digital signals from the VMEbus controller into high-voltage, high-current outputs to drive field actuators (e.g., opening a valve via a solenoid).
  2. Actuator Protection: Integrates protection features (surge shutdown, thermal shutdown) to prevent damage to actuators and the board itself during abnormal conditions (e.g., short circuits, overloads).
Core Functionality:
  • High-Current Output: Each channel supports up to 600 mA sink current, capable of driving incandescent lamps (with surge current protection) and inductive loads (with flyback protection via clamp diodes).
  • Flexible Data Transfer: Supports 8-bit, 16-bit, or 32-bit data transfer via the VMEbus, allowing compatibility with various controllers and system configurations.
  • Built-In Test (BIT): Includes test logic for fault detection and isolation, enabling offline or real-time diagnostics to ensure system reliability.
  • VMEbus Compatibility: Conforms to VMEbus Rev. C.1, ensuring seamless integration with VME64 backplanes and controllers (e.g., GE Fanuc 90-30 series).
Platform Benefits (VMEbus Series):
The VMIVME-2120 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 actuators to a turbine control system).
  • Integration: Seamlessly integrates with VMEbus-based controllers and other I/O modules, reducing setup time and effort.

Core Features & Customer Value​
1. Reliable Actuator Control:
The VMIVME-2120’s 600 mA sink current and high-voltage tolerance ensure reliable control of actuators in industrial environments. For example, in a power plant, the board can drive solenoid valves to adjust fuel flow in a turbine, ensuring stable power output.
2. Robust Protection Mechanisms:
Surge current shutdown and thermal shutdown protect actuators and the board from damage during abnormal conditions (e.g., short circuits, overloads). This reduces downtime and repair costs, which is critical for industrial facilities where unplanned outages can result in significant financial losses.
3. Flexible Data Transfer:
Support for 8-bit, 16-bit, or 32-bit data transfer allows the board to integrate with various VMEbus controllers, making it a versatile solution for different system configurations.
4. Easy Diagnostics:
Built-in test logic enables fault detection and isolation, allowing operators to quickly identify and resolve issues. This reduces troubleshooting time and improves system reliability.
