Product Introduction
The VMIVME-2536 is a high-reliability digital input/output module engineered for industrial automation, simulation, and defense systems operating on the VMEbus architecture. The board provides 32 optically isolated digital inputs and 32 optically isolated open-collector digital outputs, featuring robust optical coupling to suppress electrical noise and ground loops in harsh field environments.
It includes comprehensive Built-in-Test (BIT) capability for both input and output channels to simplify system diagnostics. During maintenance or chassis buildouts, technicians slide the 6U eurocard smoothly into designated VME card slots, engaging the rear P1/P2 DIN connectors while securing the front panel mounting screws to establish chassis ground continuity.

Compliance & Standards Alignment
When integrating legacy VME sub-assemblies into mission-critical control architectures, strict compliance documentation is required:
- Fully compliant with ANSI/IEEE STD 1014-1987 (IEC 821 and 297) VMEbus specifications.
- Tested to meet European Union CE Mark requirements, including EN55022 (Class A Emissions) and EN61000 immunity standards.
- Optical isolation barriers protect backplane logic from high-voltage transients originating on field wiring runs.
Technical Note: Verify specific jumper configurations, input voltage threshold options (e.g., 5V, 12V, or 24/28V ranges), and base address maps against your system SBC 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 components from airborne moisture and atmospheric sulfur.
- Store units in an environment where relative humidity remains strictly below 60% to halt micro-oxidation on gold-plated 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 pin arcing.
- Align the card edges precisely with the top and bottom chassis sub-rack guides, pushing evenly until the rear DIN connectors seat fully.
- Secure the front-panel captive screws tightly to guarantee low-impedance ground bonding between the frontplate and the chassis frame.
Buyer’s FAQ & Logistics
Q: What Harmonized System (HS) code applies to the international shipment of this VME I/O 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 board include mating front-panel or rear transition connectors?
A: Standard shipments include the 6U board hardware only; mating front connectors or cabling harnesses must be sourced separately based on your terminal block interface design.
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.
