        Overview Manuals I/O Data Output Wiring Compatibility Installation Check

        Product overview:

        • Integrated CPU and 100-240 V AC power supply
        • 18 24 V DC digital inputs
        • 12 relay outputs

        MLI-DR30SU combines processing, power and 30 onboard digital points in a iec su base unit.

        The integrated design supports compact stand-alone control while retaining access to compatible MasterLogic 50 expansion I/O.

        Select field protection and common wiring for the relay output stage before commissioning.

        Honeywell MLI-DR30SU is available for quotation and technical support from Apter Power.

        Verified resources for Honeywell MLI-DR30SU:

        I/O data:

        • Digital inputs: 18 at 24 V DC
        • Digital outputs: 12
        • Output stage: Relay, relay contact

        The onboard I/O allocation of MLI-DR30SU should be mapped against the application point list before replacement.

        Expansion capacity is evaluated separately from the base-unit channel count.

        Output wiring:

        • Check contact voltage and steady current
        • Allow for inductive or capacitive inrush
        • Apply suitable fusing and suppression

        Relay outputs provide isolated switching contacts; they do not provide field load power by themselves.

        Verify the voltage at the output terminal and the connected device during both commanded states.

        Compatibility:

        • Match the exact MasterLogic 50 base-unit suffix
        • Confirm expansion modules and terminal allocation
        • Verify hardware, firmware and project backup

        Replacement of MLI-DR30SU requires more than matching the total channel count.

        Power class, output technology, common arrangement and retained program data must all agree with the installed system.

        Installation check:

        • Isolate power and identify every field conductor
        • Verify supply, grounding, common and terminal torque
        • Test every I/O point and controller diagnostic

        After installing MLI-DR30SU, restore the approved application and prove the controlled sequence under site procedures.

        Record the final hardware revision, measured supply and functional-test results.

        Description
        The MLI-DR30SU is a Honeywell MasterLogic 50 base module with an integrated CPU, 100-240 V AC power supply, 18 24 V DC digital inputs and 12 relay outputs. The combined base-unit design brings controller processing, power conversion and local discrete I/O into one compact PLC assembly for machine, utility and sequence-control duties.

        The MLI-DR30SU provides 30 onboard digital points before compatible expansion I/O is added. Its relay contacts provide electrical switching flexibility, but the field circuit must remain within contact voltage, current, inrush and duty-cycle limits.

        Before installing or replacing the MLI-DR30SU, confirm the complete suffix, supply class, input commons, output wiring method, expansion-module compatibility and retained application backup. Commissioning should verify terminal torque, insulation, field-power distribution, individual point operation, diagnostics and the final safe response of connected equipment.

        Technical notes
        MLI-DR30SU integrates a 100-240 V AC supply, 18 24 V DC inputs and 12 relay outputs in one Honeywell MasterLogic 50 base unit. Confirm the exact suffix, output wiring, expansion arrangement and retained project before installation.

        VIEW ALL FAQS
        How are the 18 digital inputs on MLI-DR30SU wired?
        Use 24 V DC field signals with the correct input common and polarity, then verify the OFF and ON thresholds at the terminal under real cable and contact conditions.
        How should the 12 relay outputs on MLI-DR30SU be applied?
        Calculate steady current, inductive or capacitive inrush, contact voltage and switching frequency for each load, then apply suitable fusing and suppression.
        How many onboard I/O points does MLI-DR30SU provide?
        It provides 18 digital inputs and 12 digital outputs, for 30 onboard points before compatible expansion I/O is counted.
        Which supply must be connected to MLI-DR30SU?
        The base unit requires 100-240 V AC. Confirm the exact nameplate, protective device, grounding and available current before energizing the PLC.
        How is the MLI-DR30SU application engineered?
        Use the Honeywell MasterLogic programming environment and IEC 61131-3 logic appropriate to the controller revision; preserve and validate the approved project backup before exchange.
        Can another MasterLogic 50 base unit directly replace MLI-DR30SU?
        Only after matching supply type, 18/12 I/O allocation, relay output behavior, terminal layout, expansion hardware, firmware and application memory.
        What commissioning checks are required after fitting MLI-DR30SU?
        Inspect wiring and terminal torque, verify supply and commons, test every input and output under controlled conditions, review diagnostics and prove the machine sequence before return to service.
        What information is needed to quote MLI-DR30SU?
        Provide the exact MLI-DR30SU nameplate, hardware and firmware revision, required supply, I/O load details, expansion modules, quantity, destination and requested delivery date.
