VMIC VMIVME-4100 – VMEbus Analog Output Board for Industrial Control and Test
The VMIC VMIVME-4100 is a legacy VMEbus analog output module that’s still a solid pick when you need reliable, deterministic voltage outputs inside a 6U VME control chassis. From my experience, it suits plant upgrades, test stands, and long-life aerospace or energy systems where VME remains the backbone. You might notice that it’s typically used to generate setpoints for drives, valves, power supplies, or for analog stimulus in automated test racks. One thing I appreciate is how it fits into mixed-vendor VME systems with minimal fuss.

Key Features
- 6U VME analog output module – Designed for standard VME backplanes; integrates into legacy and extended VME64 systems in many cases.
- Multi-channel voltage outputs – Common builds provide multiple analog voltage channels (often up to 16 or 32), suitable for ±10 V or 0–10 V setpoints.
- Industrial-grade resolution – Typically 12‑ to 16‑bit DAC performance depending on the specific VMIVME‑4100 variant.
- Deterministic updates – VMEbus control with predictable timing for motion, process, and HIL/test applications.
- Field wiring via front I/O – Uses a front-panel high‑density connector; matching terminal panels/cables help keep wiring clean and labeled.
- Software-configurable behavior – Addressing and output options are usually jumper/selectable with driver support common for VxWorks and other VME OS stacks.
- Robust in installed base – Seen widely in utilities, metals, aviation test benches, and research labs that maintain VME infrastructure.
Customer note (process OEM): “We used the VMIVME‑4100 for power-supply setpoints across 24 channels. Once we standardized the terminal panels, swaps took minutes and the loop tuning stayed stable over months of runtime.”

| Operating Temperature | 0 to +55 °C (commercial temp range in most builds) |
| Signal I/O Types | Analog voltage outputs (commonly ±10 V or 0–10 V); some installations add external 4–20 mA conversion if required |
| Resolution / Update | Typically 12–16 bit DACs; update rates suitable for process setpoints and general motion control (varies by variant) |
| Communication Interfaces | VMEbus control/register access; interrupt capability and address selection via jumpers/switches in many versions |
| Installation Method | Plug-in 6U VME card; front-panel high-density field I/O; use matched shielded cable and terminal board for best results |
Related or Supporting Products
- VMIVME-4116 – Higher-resolution analog output (often 16‑bit); good when tighter setpoint granularity is needed.
- VMIVME-4120 – Higher channel density analog output; typically preferred for multi-axis benches or large I/O counts.
- VMIVME-3122 – Analog input module (complementary for closed-loop acquisition when pairing outputs with feedback).
- Associated terminal panels/cables – Use the correct front I/O cable and terminal breakout recommended for the specific connector population to maintain signal integrity.
Installation & Maintenance
- Cabinet and chassis – Mount in a 6U VME chassis with adequate airflow; leave at least one slot’s worth of airflow margin if the rack runs hot.
- Wiring – Use shielded twisted-pair for analog runs; land shields at a single point to avoid ground loops. Keep high-current loads separated from analog lines.
- Addressing and jumpers – Set the VME address space and any range/jumper options before power-up; label settings for future maintenance.
- ESD and handling – Handle by the faceplate and edges; use ESD protection. Seat firmly into P1/P2 to avoid intermittent contacts.
- Calibration – In many cases, the board supports software calibration or reference checks. Verify outputs annually (or after major maintenance) against a calibrated DMM.
- Firmware/drivers – Keep controller-side drivers aligned with the OS (VxWorks/Linux VME). If a newer CPU card is installed, re-validate the I/O library calls.
- Cleaning – Dust the chassis filters and front panel periodically; inspect the connector for debris that could introduce offset or noise.
Quality & Certifications
- Certifications (typical): CE, RoHS-compliant builds exist on many revisions; manufacturer quality systems generally ISO 9001. UL/CSA applicability varies by chassis/system.
- Manufacturer warranty: Typically 1 year on original supply; our coverage is 365 days as stated above.
- Traceability: We support serial/lot tracking where available and provide test reports when supplied by prior source.
If you’re modernizing a VME rack or need a direct analog output replacement, the VMIVME‑4100 still makes sense—especially when you want to avoid rewriting low-level I/O routines. Send your current part number and any faceplate/connector notes, and we’ll match the build variant and cable kit so it drops straight in.
