Honeywell 2MLL-CH2B Computer Link I/F Module

Product Introduction

The Honeywell 2MLL-CH2B Computer Link Interface (I/F) Module is a critical communication interface component used in Honeywell’s MLL (Modular Low-Level) control architecture. This module enables seamless data exchange between host computers and industrial control systems, providing a dependable link for real-time control, monitoring, and data acquisition in mission-critical applications.

Built to support serial communication protocols, the 2MLL-CH2B facilitates integration between supervisory systems such as SCADA or MES and Honeywell’s control hardware. With industrial-grade isolation, robust protocol support, and configurable settings, it ensures long-term, high-integrity operation even in demanding environments like refineries, power plants, and manufacturing lines.
