GE VMIVME-4150 - VMEbus 4-Channel Isolated High-Protection Analog Output Module

GE VMIVME-4150 – VMEbus 4-Channel Isolated High-Protection Analog Output Module

In stock

Product Introduction:
The GE VMIVME-4150 is a premium 4-channel analog output module for VMEbus systems, designed for the most demanding process control and safety-critical applications. The “4150” designation identifies this board as a 4-channel module with the highest level of isolation and protection in the GE VME analog output family. Unlike the standard 4140, the 4150 adds redundant isolation barriers, enhanced surge protection, and continuous self-diagnostics on every channel. This board is used where a single failed output channel cannot be tolerated, such as in nuclear plant safety systems, chemical reactor control, and pharmaceutical dosing where precision and reliability are absolute requirements.

Technical Specifications:
Board Type: VMEbus High-Precision Isolated Analog Output Module
Revision: 150 (Enhanced Protection Revision)
Channels: 4 independent analog output channels
Output Types: 4-20mA (2-wire loop powered) or 0-10V (4-wire)
Resolution: 16-bit D/A conversion with 20-bit internal processing
Accuracy: +/- 0.01% of full scale
Linearity: +/- 0.005% of full scale
Drift: Less than 1 ppm per degree Celsius (best-in-class)
Isolation: 2000V RMS channel-to-channel and channel-to-ground (double the 4140)
Settling Time: Less than 3 microseconds
Update Rate: 1ms simultaneous update for all 4 channels
Noise: Less than 5 microvolts RMS
VMEbus Interface: D32/A32 with DMA support
Power: Isolated 5V DC for output section (galvanically separated from VMEbus power)
Protection: Transient voltage suppression (TVS) diodes, fuses per channel, and crowbar circuits
Form Factor: 3U VMEbus Eurocard
Operating Temperature: 0 to 60 degrees Celsius (or -40 to +85 for extended variants)

Functional Features:
2000V Isolation: The highest isolation rating in the GE VME analog output family, protecting against catastrophic voltage transients.
Per-Channel Fusing: Each output channel has its own fuse, so a short circuit on one channel never affects the other three.
Crowbar Protection: Active crowbar circuits clamp output voltage during fault conditions, protecting both the board and the field device.
Continuous Self-Test: The board runs a continuous diagnostic on every channel, checking for drift, noise, and output stuck-at faults.
Digital Trimming: Each channel has a 16-bit digital trimmer for field calibration without removing the board.
Fail-Safe Configuration: Outputs can be configured to go to 0mA, 4mA, hold last value, or follow a predefined ramp on communication loss.
Diagnostic Memory: Stores the last 500 fault events with timestamps for post-mortem analysis.
