GE / VMIC VMIVME-1150 Product Description
Product Overview
GE VMIVME-1150 is a 64-channel optically coupled digital input board designed specifically for VMEbus-based industrial computing and control systems. Originally developed by VMIC and subsequently associated with GE Fanuc Embedded Systems, the board provides a high-density interface for acquiring discrete field signals while maintaining electrical isolation between the external signal circuits and the VMEbus control electronics. The current Abaco Systems product archive identifies the VME-1150 as a 64-bit optically coupled digital input board.
The VMIVME-1150 supports configurable input arrangements and can accommodate voltage-source, voltage-source contact-sense and logic-level input applications depending on the ordering configuration. It provides eight individually addressable 8-bit input ports and supports 8- or 16-bit VME data transfers. With high isolation and optional input filtering, VMIVME-1150 is well suited to legacy VME-based PLC, turbine-control, data-acquisition and industrial automation platforms where reliable acquisition of numerous discrete signals is required.

The exact input voltage, polarity and filtering characteristics depend on the suffix/order configuration. For example, VMIVME-1150-110 is documented as a positive-true, voltage-source + logic-input configuration with 12 V input and no filter, while VMIVME-1150-102 uses a 5 V input with a 10 μs filter.
Main Features and Advantages
64-Channel High-Density Digital Input
The VMIVME-1150 provides 64 independent digital input channels, arranged as eight contiguous 8-bit read-only ports. This high point density makes it practical for systems that must monitor a large number of discrete field conditions without occupying excessive VME rack space.
Optical Isolation for Industrial Noise Immunity
Each input is optically coupled, providing electrical isolation between field wiring and the VMEbus electronics. The documented isolation capability reaches 1,000 V sustained and 7,500 V for one second, providing substantial protection against ground-potential differences and transient disturbances in industrial environments.
VMIVME-1150
Flexible Input Configuration
A significant advantage of the VMIVME-1150 is its configurable input architecture. Depending on the ordered version, the board can be configured for voltage-source, contact-sensing or logic-level inputs. Positive-true and negative-true data polarity options are also available.
Optional Signal Filtering
Input filtering can be specified for all 64 channels using standard time constants of approximately 2 μs, 10 μs or 5 ms. This allows the board to be adapted to applications where signal noise, contact bounce or short-duration transients could otherwise produce unwanted digital transitions.
Direct VMEbus Integration
The board is electrically and mechanically compatible with the VMEbus and supports 8- and 16-bit data transfers. Individual 8-bit input ports can be addressed within the VME short I/O space, allowing the host processor or VME controller to acquire field states efficiently.
Robust Legacy-System Replacement
The VMIVME-1150 is particularly valuable for maintaining existing VME-based industrial systems. Although the product entered Abaco’s Restricted Production Phase in 2009, documentation and legacy product information remain available, and replacement/compatible VME-1150 hardware continues to be offered by specialist suppliers.
Application Fields
GE VMIVME-1150 is designed for VMEbus-based industrial automation, data acquisition, equipment monitoring and control systems. Its 64 isolated digital inputs make it particularly suitable for applications requiring large numbers of discrete status signals to be collected by a VME processor or industrial computer.
In power generation, the board can be used to acquire breaker positions, relay contacts, alarm signals, turbine auxiliary equipment status and other discrete operating conditions. Its optical isolation is useful in control cabinets where field circuits and processor electronics may operate at different electrical potentials.
In oil and gas and petrochemical facilities, VMIVME-1150 can interface with switches, interlocks, detector contacts, valve-position feedback and equipment-status signals. The configurable input filtering can help suppress unwanted transitions from mechanical contacts and electrically noisy field circuits.
In industrial manufacturing and machine automation, the module can monitor limit switches, proximity sensors, machine interlocks, conveyor status and production counters. The eight 8-bit input ports provide a straightforward architecture for grouping related machine signals.
The board is also appropriate for SCADA, transportation, defense-related embedded systems, test equipment, process monitoring and legacy VME control platforms. VMIC documentation lists the VMIVME-1150 alongside a broad range of VME digital I/O, analog I/O, serial I/O and motion-related boards, demonstrating its role as part of a larger modular VME automation ecosystem.
