CPCIs-3121 – DAQ CPCIs Card – Analog Inputs/Outputs

The CompactPCI Serial analog I/O card CPCIs-3121 has 16 SE/8 differential inputs, 16-bit, 8/4 analog outputs, 16-bit, and 8 digital I/O, 24 V.  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: 100 kHz
  • Input ranges: 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
  • 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
  • Voltage or current outputs
  • 16-bit resolution (15-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)
  • Output current ±5 mA max. for voltage outputs
  • Current outputs: 0-20 mA, min. load 10 Ω, max. load 560 Ω, at 20 mA
  • EMI filters


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


  • 2 timers, incl. 1 which can be used as a watchdog

Safety features

  • Optical isolation 500 V min.
  • Creeping distance IEC 61010-1
