Overview Manuals I/O Data Output Wiring Compatibility Installation Check

Product overview:

  • Integrated CPU and 12/24 V DC power supply
  • 16 12/24 V DC digital inputs
  • 16 relay outputs

MLI-DR32H/D1 combines processing, power and 32 onboard digital points in a iec h d1 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-DR32H/D1 is available for quotation and technical support from Apter Power.

Verified resources for Honeywell MLI-DR32H/D1:

I/O data:

  • Digital inputs: 16 at 12/24 V DC
  • Digital outputs: 16
  • Output stage: Relay, relay contact

The onboard I/O allocation of MLI-DR32H/D1 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-DR32H/D1 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-DR32H/D1, 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-DR32H/D1 is a Honeywell MasterLogic 50 base module with an integrated CPU, 12/24 V DC power supply, 16 12/24 V DC digital inputs and 16 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-DR32H/D1 provides 32 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-DR32H/D1, 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-DR32H/D1 integrates a 12/24 V DC supply, 16 12/24 V DC inputs and 16 relay outputs in one Honeywell MasterLogic 50 base unit. Confirm the exact suffix, output wiring, expansion arrangement and retained project before installation.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How are the 16 digital inputs on MLI-DR32H/D1 wired?
Use 12/24 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 16 relay outputs on MLI-DR32H/D1 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-DR32H/D1 provide?
It provides 16 digital inputs and 16 digital outputs, for 32 onboard points before compatible expansion I/O is counted.
Which supply must be connected to MLI-DR32H/D1?
The base unit requires 12/24 V DC. Confirm the exact nameplate, protective device, grounding and available current before energizing the PLC.
How is the MLI-DR32H/D1 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-DR32H/D1?
Only after matching supply type, 16/16 I/O allocation, relay output behavior, terminal layout, expansion hardware, firmware and application memory.
What commissioning checks are required after fitting MLI-DR32H/D1?
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-DR32H/D1?
Provide the exact MLI-DR32H/D1 nameplate, hardware and firmware revision, required supply, I/O load details, expansion modules, quantity, destination and requested delivery date.
