V. Comparison / Alternatives of the Same Series (Channel / Rate Trade-off)

✅ Same channel number, higher sampling rate

PCIe‑6363: 32AI/4AO/48DIO, 2MS/s, PCIe ×1, in stock (high-speed version)

✅ Same rate, fewer channels (cost-saving)

PCIe‑6341: 16AI/2AO/24DIO, 500kS/s, PCIe ×1, in stock (basic version)

✅ Compatible with older models (M series)

PCIe‑6259: 32AI/4AO/48DIO, 1.25MS/s, PCIe ×1, EOL discontinued VI. Common Questions

✅ Dual 68-pin interface: Requires 2 SHC68-68 cables, connecting AI/AO and DIO respectively

✅ 32AI + 4AO: The X series has the most channels, suitable for high-density I/O scenarios

⚠️ Sampling rate 500kS/s: The highest for a single channel is 500kS/s, with shared bandwidth for multiple channels; choose 6363 for high-speed scenarios
