APCIe-3126 – DAQ PCIe Card – Analog Inputs/Outputs

The PCI-Express analog I/O card APCIe-3126 has 16 SE inputs, 8 analog outputs, 16-bit, 8 isolated digital I/O, 24 V and additional 24 TTL I/O . The card is especially suited for applications in industrial process control, measurement technology and monitoring, for example for multichannel data acquisition, for the control of chemical processes, for the acquisition of sensor data, current measurement etc. in the harsh industrial environment.



Analog inputs

  • 16 single-ended / 8 differential inputs
  • 16-bit resolution
  • Optical isolation: 500 V
  • Throughput rate: 200 kHz
  • Input range: 0-10 V, ± 10 V, 0-5 V, ± 5 V, 0-2 V, ± 2 V, 0-1 V, ± 1 V, 0-20 mA (option); freely programmable for each channel through software
  • Gain: PGA x1, x2, x5, x10; freely programmable for each channel through software
  • PCI Express DMA for analog data acquisition

Analog acquisition

  • Single channel, multi-channel, multi-channel through sequence list
  • Automatic analog acquisition through cyclic timer control
  • Acquisition through sequence list: up to 16 entries with gain, channel, unipolar/bipolar
  • Acquisition triggered through software, timer, external event
  • Trigger functions: Software trigger or external trigger: the analog acquisition (single or sequence) is started through signal switching from 0 V to 24 V at the digital input 0.
  • Interrupt: end of single channel, end of multichannel, end of scan list

Analog outputs

  • 8 analog outputs, optically isolated (500 V)
  • Voltage outputs
  • 16-bit resolution (15-bit for 0-10 V)
  • Output range: ± 10 V, 0-10 V (switchable through software)
  • Output voltage after reset: 0 V
  • Each output has its own ground line (without optical isolation)
  • Output current ± 5 mA max. for voltage outputs
  • EMI filters


  • 4 dig. inputs including 1 interruptible input
  • 4 dig. outputs, 24 V, optically isolated


  • 24 digital TTL inputs/outputs
  • Port 0: outputs, Port 1: inputs, Port 2: inputs/outputs
  • All I/O are led to 5 V through pull-up resistors
  • Easy programming through I/O read and write commands

Timer / Watchdog
