IOU01 - Rail Compliant Discrete I/O

Welcome to the IOU01 documentation.

IOU01 integrated in ModuCop

IOU01 is a binary I/O and analog input extension unit for edge applications in rail & busses.


  • 1 slot (7 HP) extension unit for ModuCop Edge Computer
  • 2x2 digital inputs / outputs (selectable) via 4-pin spring terminal; 24V..110V (nom), load on ground or load on supply
  • 2x analog input via 4-pin spring terminal; Voltage (+/-10V) or current (4..20mA) measurement
    • 24V supply to external sensor
  • Usable for direct I/O or as data logger with multiple data streams.
  • Galvanic isolation of all inputs and outputs
  • EN 50155 compliant

IOU01 is an Io4Edge device, and therefore supports the features common to all Io4Edge devices.
