• 8 potential free, full differential voltage inputs
• Isolation voltage: 700V (Channel to Channel / Channel to PC)
• 16bit A/D-converter per channel with ynchronous sample rate
• Input voltage range : ±10,24 V, opt.: ±102,4 V
• Digital-I/O-Port (8 bit) via HDMI or pin connector
• 2 isolated trigger inputs for A/D-converter
• Monitoring of digital inputs on bit-change with interrupt generation
• Special connector block for ADQ-250-Series (ADQ-TB-ADQ-250-HUT) optional

The ALLDAQ AQ-ADQ-250 series are CompactPCI boards (PCI-Express in preparation) for high-precise and fast voltage measurements in industry and laboratory. By the potential-free voltage inputs and the full differential sampling parasitic effects like ground loops and common mode errors can be largely rejected. The input voltage range is from -10,24 V to +10,24 V for full ±10 V peak to peak. Optional an input voltage range of ±102,4 V is possible. By the high A/D converter resolution of 16 bit resp. 18 bit (depending on model) a very high accuracy is achieved without the need of switching between several measurement ranges. The 8 analog channels are electrically isolated up to 700 VRMS between each other and towards PC ground. Depending on the application you can choose between 3 models: the ADQ-255 with 8 x 16 bit A/D converters up to 250 kS/s sampling rate, the ADQ-256 with 8 x 16 bit A/D converters up to 2 MS/s sampling rate and the ADQ-258 with 8 high-precision 18 bit A/D converters sampling with 1.6 MS/s. All channels are always sampled synchronously. The values can be acquired as single values or timer-controlled. On demand the measurement can be started or stopped by two external trigger inputs, which are isolated towards PC ground and to the analog channels. The 8 bit TTL digital I/O port can be either attached by the HDMI connector at the front panel or via adapter cable to an additional mounting bracket with a 25-pin D-Sub female connector. If the digital port is configured as input the inputs can be monitored on bit-pattern change and can generate an interrupt.
