DA1
12 D/A Outputs (±10 VDC or ±25 mA)
The DA1 module features 12 independent D/A output channels with a full-scale range of ±10 VDC at ± 25 mA (max). The DA1 provides either voltage or current control loop modes that are programmable for the particular application. The DA1 module also offers external trigger/synchronization signal (RS422/485) capability, which provides/accepts a trigger signal to/from other module(s).
Features
- The module includes extensive Background Built-in-Test (BIT). In addition to output signal read-back (wrap) capabilities, overloaded outputs are detected with automatic channel shut-down protection, and the results are displayed in a status word. The modules also include D/A FIFO buffering for greater control of the output voltage and signal data. Once enabled and triggered, the D/A FIFO buffer accepts, stores, and outputs the voltage (and/or current) commands for applications requiring simulation of waveform generation (single or periodic). The output data command word is formatted as a percentage of the Full Scale (FS) range selection, which allows maximum resolution and accuracy at lower voltage ranges.
- Resolution: 16-bit/channel for either voltage (V) or current (I) command modes.
- Output Format: Single-ended
- Output Range: ±10 VDC, 0 to 10 VDC (V-control mode) or 0 to ±25 mA (I-control mode, bipolar only).
- Output Impedance: < 1 Ω
- System Protection: Output is set to 0 V at reset or Power-On.
- Linearity Error: ±0.05% FS range over temperature (Voltage mode) ±0.1% FS range @ 25º C; derates linearly to ±0.2% FS range at -40º C & +85º C (Current mode)
- Offset Error: ±5 mV / ±12.5 µA
- Gain Error: ±0.03% FS range @ 25º C; derates linearly to ±0.06% FS range at -40º C & +85º C
- Settling Time: 10 µs typ. (15 µs max.)
- Data Buffer: See Operations Manual for details.
- Load: Can drive a capacitive load of 0.1 µF, 25 mA/Ch. max. (Source or Sink). Short-circuit protected. When current exceeds 25 mA for any channel, for > 50 ms, that channel is set to 0 V (mA) and a flag is set.
- Update Rate: 5 µs per channel
- External Sync (pending): Module is provided with RS-485/422 transceiver for external channel output triggering and/or synchronization capabilities. (provides or accepts trigger signal from other module(s))
- ESD Protection: Designed to meet the testing requirements of IEC 801-2 Level 2 (4 kV transient with a peak current of 7.5 A and a time constant of approximately 60 ns).
- Power: 5 VDC @ 300 mA typical (est.); ±12 VDC @ 200 mA (est. quiescent). Add 2 mA per 1 mA load per channel.
- Ground: All channel returns (Ch-Lo (-)) are common, but are isolated (250 Vpeak) from system ground.
- Weight: 1.5 oz. (42 g)
