GE VMIVME-4140 32-Channel 12-bit Analog Output Board
Overview
Introduction Features The VMIVME-4140 Analog Output Board has 32 analog output channels with 12-bitresolution, sourcing up to 10 mA at +10 V. Each output has a dedicatedDigital-to-Analog Converter (DAC) assigned to it. The analog outputs can be disconnected from the field wiring for off-line 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 6 output voltage ranges. The VMIVME-4140 has the following features:· 32 Analog output channels- 10 mA maximum output current per channel- One 12-bit Digital-to-Analog Converter (DAC) per output channel- 0.8S2 output impedance (typical) Random update (non-scanning) or synchronous update (external or software)· Automatic calibration initiated by system reset or by software command. Unipolar (0 to +10 V,0 to +5 V, or 0 to +2.5 V) or bipolar (+2.5, +5, or +10 V) software-selectable voltage ranges. Discrete wire or mass-terminated cables
· Self-test: extensive on-board diagnostic testing capability. Outputs can be disconnected from the field. Front panel status LED. Front panel analog output connector. Front panel reference voltage accessFront panel reference voltage adjustment.
