Product Introduction
The VMIVME-1128 is a high-density, 128-channel discrete and TTL-compatible input board engineered for mission-critical industrial, aerospace, and defense applications deployed on the VMEbus architecture. The module provides robust acquisition of up to 128 digital input channels, supporting wide voltage ranges and fast data transfer options across 8-bit, 16-bit, or 32-bit VMEbus data paths.
During system integration or rack maintenance, instrument technicians slide the printed circuit card smoothly into standard 6U VME chassis card guides, ensuring the backplane P1/P2 DIN connectors engage cleanly without pin distortion. Proper chassis grounding and front-panel latching remain essential to preserve signal integrity and protect against electromagnetic interference (EMI) in high-noise environments.

Compliance & Standards Alignment
When integrating legacy VME architecture hardware into industrial or defense control loops, adherence to recognized structural and electrical frameworks is required.
- Designed to comply with ANSI/VITA 1-1994 (VME64) specifications for VMEbus backplane compatibility.
- Constructed to meet applicable CE Mark requirements for electromagnetic compatibility and low-voltage electrical safety guidelines.
- Built with internal isolation barriers on input stages to suppress transient voltage spikes and protect backplane logic lines.
Technical Note: Verify specific jumper configurations, base address mapping, and interrupt level assignments against your system master single-board computer (SBC) configuration profile prior to live bus insertion.
Storage & Asset Preservation Guidelines
VME circuit boards kept as warehouse spares require strict environmental controls to prevent component degradation:
- Keep the module hermetically sealed inside its original metallized anti-static (ESD) shielding bag to protect high-density CMOS logic devices from atmospheric moisture and sulfur-induced trace oxidation.
- Store units in an environment where relative humidity remains strictly below 60% to halt micro-corrosion on gold-plated card-edge and backplane DIN connector pins.
- For modules warehoused past a 3-year window, bench technicians should inspect electrolytic components and test the board on an offline VME test rack before live deployment.
Physical Installation Prerequisites
- Ensure the target VME chassis is completely powered down and locked out (LOTO) before module insertion to prevent bus driver contention and backplane pin arcing.
- Align the card edge carefully with the top and bottom chassis sub-rack guides, pushing evenly until the rear DIN connectors seat fully.
- Secure the front panel captive mounting screws firmly to establish a reliable chassis ground path.
Buyer’s FAQ & Logistics
Q: What Harmonized System (HS) code applies to the international shipment of this VME input board?
A: Industrial electronic computer interface and VME controller cards typically classify under HS code 8538.90 (parts suitable for use solely or principally with control apparatus). Confirm final classification details with your licensed customs broker.
Q: Does the module include rear transition modules (RTM) or mating front cables?
A: Standard shipments include the 6U board itself; mating front-panel connectors or rear transition modules must be specified and ordered separately depending on your cabinet wiring topology.
Q: Is the listed online price final for procurement?
A: Note: Price is subject to market conditions and stock availability; contact our technical sales desk for a formal, time-sensitive quotation.
