GE VMIVME-4140-001 32-Channel 12-bit Analog Output Board

GE VMIVME-4140-001 32-Channel 12-bit Analog Output  Board

DESCRIPTION

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.

Technical features

32 channels of 12-bit analogue output:

Provides 32 independent analogue output channels, each with up to 12-bit resolution.

The maximum output current of each channel is 10mA, and the output voltage range is selectable (e.g. ±10V, ±5V, ±2.5V, etc.).

High accuracy and stability:

High quality D/A converter (DAC) is used to ensure high accuracy and stability of analogue output.

Supports auto-calibration function, which is activated by system reset or software command to ensure the accuracy of the output signal.

Multiple update modes:

Supports random update (non-scanning) and software or external synchronous update of double-buffered output.

Allows users to select the appropriate update mode according to actual needs to meet the needs of different application scenarios.

Rich Diagnostic Test Functions:

Provides a wide range of on-board diagnostic test functions, including self-test and auto-calibration.

The self-test register can display success or failure and indicate the channel where the failure occurred, which is convenient for users to carry out troubleshooting and repair.

Front Panel Status and Connections:

Status LEDs are provided on the front panel to indicate the status of system reset, self-test and auto-calibration.

Front panel analogue output connectors and reference voltage access ports are provided for easy connection and configuration.

Communication and Expandability:

Supports a variety of communication interfaces (e.g., USB, PCIe, etc., specific interfaces may vary depending on the product model) to achieve fast data transfer and communication with computers.

Provide PMC expansion slots, convenient for users to expand and upgrade functions.

Multi-axis control and pulse generation (may be available on some models or configurations):

Some VMIVME-4140 models or configurations may support multi-axis control and pulse generation functions.

This can be used to accurately control the position and speed of motion devices, as well as provide precise position feedback.
