Introduction
The Honeywell 2MLI‑D22A is a 16‑channel digital input module tailored for the MasterLogic-200 PLC family. It accepts DC 24 V discrete input signals in either sink or source configuration, making it versatile for a wide range of industrial automation tasks. Thanks to its reliable input detection, robust isolation, and compact footprint, the 2MLI‑D22A is often used as a foundational component in control cabinets — especially where stable, noise‑resistant digital inputs from sensors, switches or field devices are needed.
