Material Composition
Flame-retardant industrial housing with optocoupler/relay isolation circuits. Premium conductive terminal blocks.
Structural Characteristics
Standard FBM form factor with channel identification and status LEDs. High-density backplane connector supports hot-swapping.
Working Principle
Input captures contact/voltage signals via optocoupler isolation for controller transmission. Output receives digital commands, isolates and amplifies to drive field actuators.
Installation Requirements
Insert into compatible FBM baseplate. Use shielded cables with cabinet-side grounding.
Precautions for Use
Verify signal types and terminal definitions. Never short-circuit outputs. Place node in “Maintenance Mode” before replacement.
