GE VMIVME-4140-000000 32-Channel 12-bit Analog Output Board

Technical Specifications 

The VMIVME-4140 Analog Output Board provides 32 high quality analog output channels with 12-bit resolution, and can source or sink 10 mA at ±10 V. Each output has a dedicated D/A Converter (DAC) assigned to it. The analog outputs can be disconnected from the field wiring for offline testing. Calibration and self-test are initiated by a VMEbus system reset or by execution of a software command. During calibration, a table of offset and gain coefficients is compiled and stored in RAM. There is an entry for offset and gain corresponding to each of the 32 channels configured in each of the six output voltage ranges.

Functional Characteristics

Self-Test Function:Built-in self-test automatically runs after system reset. The self-test register provides pass/fail status and identifies failed channels.
Output Isolation Function:Analog outputs can be disconnected from field wiring to support offline testing and system diagnostics.
Front Panel Interface:Provides front panel analog output connector, status LED indicator, and reference voltage access.
Reference Voltage Function:Includes a single reference potentiometer for analog output reference adjustment.
VMEbus Control:Operates as a VMEbus analog output board with software-controlled configuration and operation.
