The EasyIO-DEM-5 provides five digital Inputs using a specific resistor-to-resistor network connected to Universal Input. The EasyIO-DEM-5 expander allows a single universal input (with capability to measure resistance between 700Ohm to 1600 Ohm) to monitor the status of up to five dry contacts.




  • 24VAC or 24DC power supply input.
  • Status Indicator
    Built-in power and input LEDs indication and diagnostic
  • Jumper
    Built-in internal jumpers for easy diagnostic.
  • Relay Drive
    External dry contact is driven by relay supports higher
    impendence load.
  • Ease of Installation
    All I/Os are connected via field removable terminal block connectors for easy maintenance. The controller casing fits standard DIN rail mounting.
