IO Module

Description

The IO Module provides six individually configurable ports, each one has multimeter capabilities.

The key features are: Software

Hardware

  • 6 individually configurable ports.
  • Each port supports the following functions:
    • Analog Input
    • Digital Input with frequency counter
    • Current measurement (output)
  • Each port can be configured via software as 5V or 12V output.
  • All ports are protected against voltages up to 50V (see below).
  • Up to 6W output power per port.
  • Active overload protection
    • Includes voltage, current and power monitoring.
    • Configurable voltage and power limits.
    • Typical reaction time <5ms.
    • Notification support, error triggers software notification for the application.
  • Failsafe design
    • In case of power failure or software problem, the ports are automatically disconnected via relay.
    • Each port has physical fuses for extreme cases.
  • Continuous monitoring of voltage, current and power with 1000 samples per second/port.
  • Good ESD and surge protection allows direct control of inductive loads.
  • Large temperature range -40°C – 85°C.

Applications

  • Relay control
  • Fan control
  • Motor control (PWM)
  • Electronic door lock control
  • Door/Window open/closed detection
  • LED control
  • Analog sensor reading (temperature, humidity, photodetector… )
