Introduction
The Honeywell 2MLI‑D24A is a high-density digital input module designed for the MasterLogic‑200 PLC family. With 32 DC 24 V input channels in a compact form factor, it allows industrial automation systems to capture a large number of discrete signals from sensors, switches, or contact closures. Its sink/source configurable inputs and robust photo‑coupler isolation ensure reliable and noise‑resistant operation, making it ideal for complex manufacturing, process control, and machine automation applications where stability and precision are essential.
