Product
DSP AD5430-02A(8ch general purpose D/A board)
Features
This board has a DA feature that produces an analog output (8ch voltage) controlled by the output indication value from the control CPU.
It has a user-defined waveform output feature that produces an analog output of the indication values (4ch voltage) on in its memory,
with a timing given by the internal/external timing signal.
It also has a resistance simulator feature that can be used for an application that
outputs a voltage signal corresponding a sensor with a variable resistance value, such as a thermistor.
- User-defined waveform output feature:: Outputs a waveform pattern that was registered in the user file with a set timing.
- Resistance simulator feature: Simulates voltage drop by the resistance. (Injection current must be is less than 5 mA).
Specifications
| Output specification | Single-end voltage output |
|---|---|
| DA feature | 8ch 4 selections for number of output channels: 1ch, 2ch, 4ch, or 8ch |
| User-defined waveform feature | 4ch User defined waveforms are fixed on 1ch to 4ch When user-defined waveform output is selected, the 5th through 8th channels remain available to the DA feature. The user defined waveform feature can be selected in software. |
| Resolution | 12bit |
| Conversion speed | 10 µsec / ch (100 kHz) |
| Conversion output feature DA feature User-defined waveform feature |
Outputs a voltage whose value is set by the output indication value from the control CPU. Outputs a voltage determined by the indication value in the memory with an (internal / external) timing. The conversion output feature can be selected in software. |
| Output range | Unipolar output: 0 to 1 V, 0 to 5 V, 0 to 10 V Bipolar output: 0 to ±1 V, 0 to ±5 V, 0 to ±10 V The output range can be selected for each channel via software. |
| Accuracy | For each range: ±0.1% of full scale (23 ±5°C) |
| Output current | Output current: 5 mA, Input current: 20 mA |
| Output impedance | 10 Ω or smaller |
| Isolation | Bus is isolated |
| Internal timing clock (For user-defined waveform output) |
Channel: 1ch Period: 100 kHz to 1 Hz, 1, 2, 4, 5, or 8 step setting |
| External timing signal input (For user-defined waveform output) |
Input channel: 1ch Period: to 100 kHz Input type: DC 5 V to 24 V (voltage input) Synchronous timing: can be selected from rise or fall |
- The output timing of the DA feature is synchronous to the model operation cycle.
- The user-defined waveform output feature is synchronous to the internal timing signal or the external timing signal.
- When using the user-defined waveform output feature and assigning the other channels to the DA feature, the DA feature output is synchronous to the signal for the user-defined waveform output feature.
