- Bus Interface: 2 Mbps Redundant HDLC Fieldbus
Functional Features
- Seamless Expansion: Provides additional 16-channel DC I/O when paired with base FBM modules.
- High Reliability Verification: Bit-by-bit matching ensures expansion channel data accuracy.
- Electrical Isolation: High-impedance isolation between channels and bus.
- Smart Diagnostics: Wire break detection and module health reporting.
Application Scenarios
Large valve array monitoring, complex safety interlock systems, and distributed remote I/O stations requiring extensive discrete points.
Performance Parameters
- Response Time: Millisecond-level state capture.
- Protection Rating: IP20.
- Environmental Rating: ISA S71.04 G3 certified.
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, typically adjacent to base FBM modules. Use shielded cables with cabinet-side grounding.
Precautions for Use
Verify signal types and terminal definitions. Never exceed rated voltage limits. Disable corresponding node in software before replacement.
