Honeywell 2MLR-DBST I/O Interface Module

The Honeywell 2MLR-DBST is an electrical expansion driver I/O interface module engineered for Honeywell MasterLogic-200 redundant CPU systems, including 2MLR-CPUH/T and 2MLR-CPUH/F processors. It establishes twisted-pair Category 5 electrical communication links between the main CPU chassis and downstream expansion base assemblies.

Base Expansion and Communication Links

The module installs into the CPU parts section (CPU0 connector) of an expansion base to drive communication signals across expansion racks. Utilizing electrical transmission media over TP/CAT5 cabling, it supports maximum point-to-point distances of up to 100 m between expansion bases.

System Addressing and Loader Connectivity

The module accommodates expansion station numbers configured within a range of 1 to 31, where selecting any address outside this range generates a system fault error. It also incorporates an extension drive USB connection for loader interface routines and diagnostic communication.

Frequently Asked Questions

Q: Which CPU processors are compatible with the 2MLR-DBST interface module?

A: It is designed for use with Honeywell MasterLogic-200 2MLR-CPUH/T and 2MLR-CPUH/F CPU modules.

Q: What is the maximum distance supported between expansion bases?

A: The electrical TP/CAT5 link supports a maximum distance of up to 100 m between expansion bases.

Q: What station address range can be assigned to the module?

A: The valid station number range is 1 to 31; assigning any station address outside this boundary will generate an error.
