GE-VMIVME-4140

Description: The VMIVME-4140 analog output board provides 32 high-quality 12-bit analog output channels with high resolution and can send or receive 10ma at +10 V voltage. Each output has a dedicated D/ a converter (DAC) assigned to it. The analog output can be disconnected from field wiring for off-line testing. Calibration and self-test are reset by the VMEbus system or performed by software commands. During calibration, a bias and gain table coefficient is compiled and stored in RAM. There is an entry for each of the 32 channels corresponding to the bias and gain configurations in each of the six output voltage ranges. Self-check: The system starts automatically after a reset. The self-check register indicates success or failure and can indicate the channel where the failure occurred. Status indicator on the front panel: If the indicator turns on one second later, the system resets. When successful, the LED lights go out to complete the self-test and automatic calibration. Leds can also be turned on and off under software control.
