VMIVME-4140-001 analog output circuit board is a 32-channel, 12-bit analog output circuit board from GE, VMIVME-4140-001 is its specific model, the following is a detailed introduction:

Functional characteristics

Analog output channels: 32 analog output channels with 12-bit resolution can output or absorb 10mA current at ±10V voltage, and each output has A dedicated D/A converter (DAC).

Output characteristics: The output impedance is 0.8Ω, can be randomly updated (non-scanning), support software or external synchronous update dual buffer output.

Calibration and self-test: Analog outputs can be disconnected from field wiring for off-line testing. Calibration and self-test can be initiated by the VMEbus system reset or by executing software commands, during which the offset and gain coefficient tables are compiled and stored in RAM. After the system is reset, the self-test will automatically run, and the self-test register can show success or failure, and show the fault channel.

Voltage selection: The output voltage can be selected via the software in the unipolar (0 to + 10V, 0 to + 5V, 0 to + 2.5V) or bipolar (±2.5, ±5 and ±10V) range.

Other functions: The front panel has the status LED, the LED lights up after the system reset, after the self-test and automatic calibration is successful, the LED goes out, it can also be opened or closed under software control; The front panel also has analog output connectors and reference voltage access interfaces for corresponding reference voltage adjustment
