Honeywell 2MLR-DBSF I/O Interface Module

The Honeywell 2MLR-DBSF is an I/O Interface Module specifically engineered to facilitate optical communication between expansion bases in industrial control systems. This module enables high-speed, noise-immune data transmission over fiber-optic media, supporting a maximum distance of 2 km between connected bases. It utilizes a 62.5/125 multi-mode fiber configuration with standard LC-type connectors to ensure reliable connectivity in environments where electromagnetic interference may be a concern.

Features

• Media Type: Optical fiber communication
• Expansion Distance: Up to 2 km between expansion bases
• Connector Type: LC (Lucent Connector)
• Signal Integrity: Return loss exceeding 45 dB
• Station Addressing: Supports station numbers 1 to 31
• Connectivity: Dedicated CPU0 connector interface on the expansion base
• Local Configuration: Includes an expansion drive USB port for loading

Applications

• Distributed I/O systems across expansive industrial facilities
• High-EMI environments requiring fiber-optic noise immunity
• Long-distance remote rack communication in DCS or PLC architectures

Technical Specifications

Installation Guidelines

• Module Placement: The module must be installed in the CPU0 connector slot located on the expansion base.
• Fiber Handling: Ensure that fiber optic cables are handled with care, maintaining the specified bend radius to prevent signal degradation.
• Connector Cleaning: Always inspect and clean the LC connectors before insertion to maintain the required return loss performance.
• Addressing: Ensure each module is configured with a unique station number within the 1-31 range; setting a value outside this range will result in a communication error.
• USB Loader: Utilize the dedicated expansion drive USB port for system loading and maintenance tasks.
