Description

Product Description

GE VMIVME-4150 is a 6U VMEbus isolated 12-bit analog output board from GE Fanuc VMIC, built for high-precision signal conversion in industrial automation and process control systems. GE VMIVME-4150 offers 4/8/12 fully isolated channels (1000 VDC standard isolation, up to 1500 VDC optional) for channel-to-channel and channel-to-bus protection. GE VMIVME-4150 supports software-selectable voltage ranges (±2.5V/±5V/±10V unipolar/bipolar) and optional 4-20mA current loops, with 0.05% voltage accuracy and 0.08% current loop accuracy. GE VMIVME-4150 integrates optical data coupling for full galvanic isolation, static readback registers for program control, and front-panel access for field wiring and diagnostics. GE VMIVME-4150 operates stably in -40°C to +70°C industrial environments, with outputs automatically placed in a minimal state at reset and a front-panel Fail LED for fault indication. GE VMIVME-4150 is ideal for VME-based control systems, including GE Mark VI, where reliable analog output and isolation are critical for safety and precision.

Selection Suggestions and Precautions

Selection Suggestions

  • Choose GE VMIVME-4150 for VME-based control systems needing 4-12 isolated analog outputs with high precision and wide environmental tolerance.
  • Opt for 12-channel/1500 VDC isolation for power plants or refineries; 4/8-channel for smaller robotics/water treatment setups.

Precautions

  • Use GE VMIC configuration tools to set output ranges and test minimal-state reset behavior of GE VMIVME-4150.
  • Verify isolation voltage (1000 VDC standard) matches your system’s EMC/grounding requirements before installation.
  • Check VMEbus compatibility (32-bit/33MHz) when integrating GE VMIVME-4150 with legacy control systems.
  • Avoid hot-swapping GE VMIVME-4150; power down the VME chassis first to prevent bus damage.
  • Calibrate outputs annually using on-board circuitry to maintain 0.05% voltage/0.08% current accuracy.
