APCI-3120 – DAQ PCI Card – Analog Inputs/Outputs

The PCI analog I/O cards APCI-3120 has 16 SE/8 differential inputs, 16-bit, 8/4 analog outputs, 14-bit, and 8 digital I/O, 24 V. The card is especially suited for applications in the sector of 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 etc. A timer, that can be used as cyclical time counter or as watchdog is available.



Analog inputs

  • 16 single-ended/8 differential inputs or 8 single-ended/4 differential inputs
  • 16-bit resolution
  • Optical isolation 500 V
  • Throughput: 100 kHz
  • Input voltage: 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 through software for each channel
  • Gain PGA x1, x2, x5, x10 freely programmable through software for each channel
  • PCI DMA for analog data acquisition
  • Overvoltage protection
  • Input filters: 159 kHz

Analog acquisition

  • One single channel, several channels, several channels through scan list
  • Automatic analog acquisition through cyclic timer control
  • Acquisition through scan 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

  • 4 or 8 analog outputs, optically isolated 500 V
  • Setup time 10 µs typ.
  • 14-bit resolution (13-bit for 0-10 V)
  • Output voltage: ±10 V, 0-10 V (through software)
  • Output voltage after reset: 0 V
  • Each output has its own ground line (without optical isolation)
  • Driver capacity: 5 mA/500 pF
  • Short-circuit protection, EMI filters

24 V digital I/O

  • 24 V digital I/O enable a high interference distance and a long distance between signal transmitter and data acquisition
  • 4 digital inputs, 24 V, optically isolated
  • 4 digital outputs, 24 V, optically isolated


  • 4 dig. inputs, 4 dig. outputs, 24 V, optically isolated


  •  As cyclic time counter or as watchdog
