Overview

The Honeywell 2MLI‑A12A is a 16-point digital input module engineered for AC 110 V discrete signals. Designed for the MasterLogic-200 (ML200 / ML200R) platform, it reliably collects field input data from devices such as switches, sensors, and status contacts. With rapid response times, robust photocoupler isolation, and a compact footprint, this module ensures accurate, noise-free digital signal acquisition for industrial automation, machine control, and process monitoring applications.
