PA-1508 – DAQ Card – Analog Inputs/Outputs

The PA-1508 16 digital input/output ISA card has 8 digital inputs, 24 V, and 8 digital outputs, 24 V. All the inputs are opto-isolated. It is used for industrial I/O control, for automatic test benches, as an interface to electromagnetic relays, for status monitoring (on/off) of motors, lamps, etc. or alarm activation in a harsh industrial environment and has a number of safety devices to do this. A CD-ROM containing drivers for Windows and programming examples is included.



8 digital inputs, 24 V, isolated

  • 2 connection lines per input
  • Parallel acquisition of digital 24 V signals
  • Each input channel has its own ground line

8 digital outputs, 24 V, isolated

  • Each output channel can be triggered independently from the others
  • The output channels are current-limited and suitable for loads with high inductive currents
  • 2 diagnostic outputs generate LOW level at overtemperature
  • Watchdog: can be activated through software, readable
  • After power-on the outputs are reset to “0”
  • Addressing through DIP switches

Safety features

  • Optical isolation 1000 V
  • Voltage supervision
  • Creeping distance IEC 61010-1 (VDE411-1)
  • Safety for the inputs: voltage reversal protection, LC filters
  • Safety for the outputs: Overtemperature protection: Shut-down logic at approx. 125-140 °C, short-circuit current at 1.5 A, Shut-down logic, when the external supply voltage drops below 5 V.
  • Safety features for the ext. supply voltage: overload protection: self-resetting fuse (electronic fuse), overvoltage protection through varistors and transorb diodes, screened through LC filters

EMC tested according to 89/336/EEC (CE certification)

  • IEC 61326: electrical equipment for measurement, control and laboratory use


  • Industrial I/O control
  • Automatic test equipment
  • Interface to electromechanical relays
  • Monitoring of 24 V signals
  • Activation of alarm
  • Signal switching
