Introduction
The Honeywell 2MLI‑A12A‑CC is a rugged, industrial‑grade 16‑point AC 110 V digital input module built for the MasterLogic‑200 (ML200 / ML200R) platform. It is designed to reliably collect discrete field signals — like switches, contact closures, sensors — and feed them accurately into your PLC logic. With durable photo‑coupler isolation, compact form factor, and fast response, this module makes integrating AC‑powered field devices into automation systems straightforward and robust.
