      Information

      Overview Manuals Common Applications Product Precautions
      ABB IMASI23 provides the Universal Analog Input Module function within Harmony Rack I/O installations.
      • Combines multiple analog signal families in one rack module
      • Conditions field measurements before controller access
      • Uses the Harmony mounting-unit backplane connection
      • Supports temperature and electrical process variables

      IMASI23 operates with Harmony module mounting unit, matched termination device, I/O expander bus, Harmony multifunction controller.
      Typical engineered duties include Process transmitter input racks, Millivolt sensor acquisition, Thermocouple measurement panels, RTD temperature monitoring.

      Important Notice: IMASI23 must be commissioned with the exact channel signal definition, termination arrangement and controller database used by the installed Harmony rack.

      IMASI23 engineering must match each configured signal family to the assigned termination device, Harmony rack position and controller database. Verify channel scaling, sensor wiring and module diagnostics during commissioning.

      FAQS

      • Which signal families are supported by IMASI23?
        ABB lists current, voltage, millivolt, thermocouple and RTD input families for IMASI23.
      • Can IMASI23 read a 4-20 mA transmitter?
        Yes. Select the current-input configuration and apply the project loop-power arrangement.
      • Which voltage ranges can be configured on IMASI23?
        The ABB overview lists 0-5 VDC, 1-5 VDC and 0-10 VDC ranges.
      • How should an IMASI23 temperature channel be commissioned?
        Confirm sensor type, termination wiring, compensation method and engineering-unit scaling.
      • What rack interface carries IMASI23 data?
        The Harmony I/O expander bus links the rack module to the controller through the mounting-unit backplane.
      • What must be checked before replacing IMASI23?
        Compare the full identifier, channel configuration, termination hardware, cable assignment and rack address.
      • How should IMASI23 wiring changes be controlled?
        Use the loop drawings and preserve shield, polarity and terminal assignments for every channel.
      • What proves an IMASI23 installation is ready?
        Stable module status plus verified channel values, scaling and alarm behavior complete the commissioning evidence.
