HONEYWELL 2MLI-D28B Digital Input Module – Experion PKS Series
When a digital input module fails on the plant floor, the consequences are immediate and severe. Process controllers lose visibility into field device states — limit switches go unread, valve positions become unknown, and safety interlocks may fail to respond. Production halts, alarms cascade, and maintenance teams scramble under pressure. The HONEYWELL 2MLI-D28B is the precision-engineered solution that keeps your Experion PKS control system fully informed and your process running without interruption.
The 2MLI-D28B occupies a critical position within Honeywell’s Experion PKS (Process Knowledge System) platform — one of the most widely deployed DCS architectures in the global process industries. Designed for high-density discrete signal acquisition, this module delivers the deterministic, fault-tolerant performance demanded by refining, petrochemical, power generation, and advanced manufacturing environments worldwide.
