Description
The VMIVME-4514A is a 16-Channel, 12-bit Analog Input/Output (AIO) Board. It provides both the stimulus and the response functions encountered in VME bus based closed-loop analog systems. The analog signals are available at the P2 backplane connector. It is self-contained, with a resident 12-bit Analog-to-Digital Converter (ADC) and a Digital-to-Analog Converter (DAC). The board also supports a Built-in-Test feature that checks all of the active components on the board. The VMIVME-4514A provides a single board solution to the analog input/output requirements of such VME bus applications as process control, simulators, trainers, and supervisory control.
The VMIVME-4514A provides the user with 16 analog outputs with 12 bits of resolution. The outputs are designed with individual Sample-and-Hold (S&H) amplifiers, one per channel. The outputs can be programmed (via on-board jumpers) to operate in a variety of voltage ranges. These ranges are 0 to +5 V, 0 to +10 V (unipolar), ±2.5, ±5.0, or ±10 V (bipolar). Each output can source or sink up to 10 mA at ±10 V. The outputs can be disconnected from the I/O connector for off-line testing.
The board also accepts 16 analog inputs. These inputs may be differential or pseudo-differential (single-ended). A 36 Hz single pole input filter may be ordered for the inputs. The input ADC can be programmed (via on-board jumpers) to operate in a variety of voltage ranges. These ranges are 0 to +5 V, 0 to +10 V (unipolar), ±2.5, ±5.0, or ±10 V (bipolar). The inputs have 12 bits of resolution. The inputs can be scanned by on-board multiplexers, and the data stored in a dual port memory.
The VMIVME-4514A has three ADC operating modes. They are Random Polling, Scanning Poll, and Auto Scanning. Auto Scanning Mode is entered when power is applied to the board, after a system reset, or under program control. In this mode, all 16 channels are continuously scanned. Their inputs are digitized and stored in sixteen 12-bit dual port registers. No programming is required other than reading the data from these registers.
