PA-2000 – DAQ Card – Digital Outputs

The PA-2000 32 digital output ISA card has 32 digital outputs, 24 V, 3 timers and 1 watchdog. The card has galvanic isolation and is protected against fast transient effects (burst), electrostatic discharge and high frequency interference. It is used as an interface to machines or electromagnetic relays, for status monitoring (on/off) of motors, lamps etc. in a severe industrial environment and has numerous safety devices to do so. A CD-ROM containing drivers for Windows and programming examples is included.



32 digital outputs, 24 V, isolated

  • Output current: 500 mA
  • Voltage range: 10 to 36 V
  • Diagnostic reports, readable through status register in case of short-circuit, overtemperature, voltage drop or watchdog
  • 3 x 16-bit timer (82C54): Timer as programmable watchdog for the reset of the outputs to “0”, function release through software, control of 2 output channels for generating square-wave signals
  • Interrupt triggered through error on the outputs or through timer2
  • Addressing through DIP switches
  • 16-bit or 8-bit data bus
  • After power-on the outputs are reset to “0”
