      Information

      Information

      Overview Manuals Common Applications Product Precautions
      ABB IMASI03 provides the Universal Analog Input Slave Module function within INFI 90 / Harmony Rack I/O installations.
      • Acquires mixed analog field signals
      • Transfers converted values over the slave expander bus
      • Applies channel-specific signal conditioning
      • Supports open-input and module-status diagnostics

      IMASI03 operates with IMMFP01/02/03 multifunction processor, NTAI06 termination unit, NIAI05 termination modules, NKAS termination cables.
      Typical engineered duties include Thermocouple temperature acquisition, Three-wire RTD measurement, Process current-loop monitoring, Low-level millivolt sensing.

      Important Notice: IMASI03 channel type, address, jumper position and MFP function-block definition must agree before field power is applied.

      Read the applicable ABB installation instructions before work. Verify IMASI03 and the installed-system configuration.
      1
      Confirm IMASI03 and the assigned MMU position before handling.
      2
      Set the SW1 slave address before inserting IMASI03.
      3
      Configure each channel jumper for its electrical input family.
      4
      Match NTAI06 or NIAI05 hardware and the NKAS cable arrangement.
      5
      Confirm the Function Code 215/216 address and active-channel definitions.
      6
      Inspect MMU contacts and termination-cable seating before applying power.
      7
      Start the MFP and confirm IMASI03 status indication and channel quality.
      8
      Calibrate the active inputs and record the completed functional test.

      Technical notes

      Technical notes

      IMASI03 engineering must match the selected analog or temperature signal family to the NTAI06 or NIAI05 termination hardware and the assigned INFI 90 controller path. Verify input scaling, compensation wiring and module diagnostics during commissioning.

      FAQS

      • Which termination hardware works with IMASI03?
        Use one NTAI06 termination unit or two NIAI05 termination modules with the applicable NKAS cable arrangement.
      • How is the slave address set on IMASI03?
        Use SW1 and keep its normal-operation contacts in the manual-defined positions while assigning the six-bit bus address.
      • Can IMASI03 accept thermocouples?
        Yes. Configure the channel input family, cold-junction treatment and function block for the selected thermocouple type.
      • How should a three-wire RTD be connected to IMASI03?
        Use the manual-defined resistance jumper setting and land the three leads on the matched termination hardware.
      • What must be configured in the MFP for IMASI03?
        The MFP requires the IMASI03 slave address, active channel definition, signal type and engineering scaling.
      • How is IMASI03 commissioned after replacement?
        Verify address, termination cabling, channel configuration, LED state and each active process value.
      • What does a red IMASI03 status indication require?
        Follow the IMASI03 diagnostic sequence and separate power-up, communication and fatal module conditions before replacement.
      • Can IMASI13 replace IMASI03 without configuration work?
        No. ABB's replacement procedure requires resolution and function-code checks before the substitution is accepted.
