2MLR-E08P-CC | Honeywell | Expansion Base

The Honeywell 2MLR-E08P-CC is an eight-slot expansion base engineered for Honeywell MLR-series control and I/O modules. It serves as the physical chassis and backplane interconnection hub, supplying regulated DC power distribution and backplane communication paths for medium-scale industrial automation assemblies.

Backplane Functionality and Power Distribution

The base routes regulated DC power directly through its integrated backplane to feed all installed modules across its eight slot positions. Designed for panel mounting, its construction includes internal isolation between field wiring terminations and the internal system bus to protect control electronics from field transients.

System Integration and Module Flexibility

The chassis supports mixed installations of MLR-series control and I/O modules within the same base assembly. Its mechanical layout allows individual modules to be removed or replaced without disturbing adjacent field wiring connections, supporting system maintenance routines.
