Material Composition
High-reliability electronic components on multi-layer PCBs with conformal coating. Die-cast aluminum enclosure.
Structural Characteristics
Standard I/A Series module form factor. Compact and lightweight (0.6kg) for high-density panel layouts.
Working Principle
Cyclically scans all connected I/O modules, executes the user-defined control strategy, and communicates with the operator station and higher-level systems via the fiber optic network.
Installation Requirements
Install in the designated processor slot. Ensure fiber optic cables are handled with care to avoid bending radius violations.
Usage Precautions
- Avoid exposing the fiber ports to dust; use protective caps when disconnected.
- Monitor CPU load via the diagnostic software to prevent overload.
- Ensure the module is properly grounded to the chassis.
