Material Composition
Industrial-grade flame-retardant housing with high-reliability optocoupler isolation. Premium conductive terminal blocks.
Structural Characteristics
Standard fieldbus module with clear channel labeling and LED indicators. Precision backplane connector for secure mounting.
Working Principle
External DC signals or contact closures pass through optocoupler isolation and level conversion, converting to digital logic levels for redundant fieldbus transmission.
Installation Requirements
Mount on compatible FBM baseplate. Use shielded cables with cabinet-side single-point grounding.
Precautions for Use
Verify signal types and terminal definitions. Never exceed rated voltage limits. Disable corresponding node in software before replacement.
