PA 1508 Digital I/O Board

Quick Overview

The PA1508 is a digital I/O board with 8 digital inputs and 8 digital outputs. All inputs are filtered with 2 diagnostic outputs and 1 programmable watchdog, plus each input channel has an individual ground connections. All output channels can be triggered independently with DIP switch addressing. The board is optically isolated up to 1000V and protected against overvoltage. The PA1508 is suitable for applications such as industrial I/O, automatic test equipment, interface to electrochemical relays, etc. A CD-ROM with software drivers and programming examples is supplied with the board.

Features

  • 8 digital inputs, 24V, 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

Applications

  • Industrial I/O control
  • Automatic test equipment
  • Interface to electromechanical relays
  • Monitoring of 24 V signals
  • Activation of alarm
  • Signal switching
  • ON/OFF monitoring of motors, lights...
  • Machine interface
