Description

Honeywell 2MLI-D22A-CC Digital Input Module – Experion PKS Distributed Control System

When a digital input module fails on a live process line, the consequences are immediate and severe: operators lose visibility into field device states, safety interlocks may become unreliable, and unplanned shutdowns cascade across the entire plant. In refining, power generation, and chemical processing, even minutes of blind operation translate into significant production losses and safety risks. The Honeywell 2MLI-D22A-CC Digital Input Module is the precision interface that keeps your DCS fully aware of every discrete field signal — making it an indispensable component in any Experion PKS control architecture.

The 2MLI-D22A-CC occupies a critical position within Honeywell’s Experion PKS (Process Knowledge System) platform — one of the most widely deployed DCS solutions in global heavy industry. As a 24-channel digital input module with CC (Control Cabinet) form factor, it is engineered for high-density I/O applications where signal integrity, hot-swap capability, and seamless integration with the Experion server are non-negotiable. Its adoption spans upstream oil & gas, LNG terminals, nuclear auxiliary systems, and large-scale utilities worldwide.

Key Features & Benefits

High-Density I/O: 24 channels per module maximizes cabinet space efficiency and reduces wiring complexity in large-scale DCS installations.
Optical Isolation: Protects the Experion PKS backplane from field-side transients, ground loops, and electrical noise common in industrial environments.
Hot-Swap Capability: Replace or insert the module without shutting down the controller — critical for continuous-process industries where downtime is not an option.
Seamless Experion Integration: Auto-recognized by the Experion server; configuration is managed through Control Builder with minimal engineering effort.
Diagnostic Transparency: Module-level and channel-level diagnostics are surfaced directly in the Experion operator station, enabling rapid fault isolation.
Robust Construction: Designed for 24/7 operation in harsh industrial environments with wide temperature tolerance and vibration resistance.

Industry & Equipment Applications

Oil & Gas: Upstream wellhead control panels, offshore platform DCS, pipeline SCADA integration points
Refining & Petrochemical: Distillation column monitoring, reactor interlock systems, compressor status feedback
Power Generation: Turbine auxiliary control, boiler management systems, switchgear status monitoring
LNG & Gas Processing: Cryogenic plant I/O, liquefaction train control cabinets
Chemical & Pharmaceutical: Batch process control, safety instrumented system (SIS) integration
Water & Utilities: Pump station monitoring, valve position feedback, flow switch inputs

System Integration & Compatible Parts

The 2MLI-D22A-CC is designed to operate within the Honeywell Experion PKS Modular LCI architecture. Compatible and commonly paired components include:
