Introduction

The Honeywell 2MLI‑D22A‑CC is a 16‑point DC 24 V digital input module designed for the MasterLogic‑200 (ML200 / ML200R) PLC platform. It provides reliable, flexible, and noise‑resistant acquisition of discrete DC signals from sensors, switches, and other field devices, transmitting them efficiently into your control logic. With a compact design, configurable input behavior (sink or source), and robust isolation, this module is ideal for industrial automation, machine control, and process-level discrete I/O applications requiring stable and accurate digital input detection.

Applications

  • Reading discrete DC‑24 V sensor signals, push‑buttons, limit switches, or proximity switches in machinery and automation lines

  • Expanding input capacity of MasterLogic‑200 PLC racks, especially where multiple digital inputs are needed

  • Machine control, conveyor management, packaging lines, or assembly automation requiring robust and clean DC inputs

  • OEM control cabinets or custom control panels needing modular, flexible, and dense digital I/O

  • Process plants, utilities, or infrastructure automation systems where DC 24 V logic is standard


Advantages

  • Flexible wiring — sink or source: supports both wiring methods, giving engineers flexibility to adapt to different field device types.

  • Compact high-density I/O: 16 input channels in a single module save rack space and simplify wiring layouts.

  • Configurable response time: selectable response times (as fast as 1 ms) enable tuning for either noise immunity or fast switching needs.

  • Strong signal isolation: photo‑coupler isolation protects PLC logic from electrical noise and transients common in industrial environments.

  • Visual status indicators: per‑channel LEDs make diagnostics, troubleshooting, and maintenance faster and easier.

  • Standard DC 24 V compatibility: ensures straightforward connection with common industrial sensors and devices without additional converters.


Technical FAQs (10)

  1. Q: How many input channels does 2MLI‑D22A‑CC offer?
    A: 16 discrete DC input channels.

  2. Q: What input voltage does it expect?
    A: DC 24 V nominal (operating range DC 20.4–28.8 V).

  3. Q: Does it support both sink and source wiring?
    A: Yes — the module supports either sink or source wiring configuration.

  4. Q: What is the ON / OFF threshold for inputs?
    A: ON ≥ 19 V DC & ≥ 3 mA; OFF ≤ 11 V DC & ≤ 1.7 mA.

  5. Q: What is the input resistance?
    A: About 5.6 kΩ.

  6. Q: How fast does the module detect input changes?
    A: Response time configurable — from 1 ms up to 100 ms; default is 3 ms.

  7. Q: How are the inputs isolated from the PLC logic?
    A: Via photo‑coupler isolation, which enhances noise immunity and protects internal logic.

  8. Q: What wiring method and connection interface does it use?
    A: 18‑point terminal block (M3 screws), using twisted‑pair cable of 0.3–0.75 mm².

  9. Q: Does it include status indicators for each input?
    A: Yes — each input channel has an LED that lights when the input is active.

  10. Q: What kinds of applications suit this module best?
    A: Industrial automation, machine and conveyor control, OEM control panels, process monitoring systems, and any application requiring modular DC‑24 V digital inputs.
