Performance Parameters
- Processing Speed: 0.1 µs/boolean, 0.5 µs/floating point.
- Power: 24VDC, 10W, redundant power input supported.
- Environment: 0℃ to 60℃ operating range, G3 harsh environment rating.
Material Composition
Robust die-cast aluminum housing providing superior EMI shielding and thermal dissipation.
Structural Characteristics
Dimensions: 140mm × 165mm × 45mm. Weight: 0.6kg. Front panel includes comprehensive diagnostic LEDs.
Working Principle
Executes control logic in parallel on two processors. A high-speed sync bus continuously compares internal states. If a discrepancy or failure is detected, the system instantly transfers control to the healthy module without process interruption.
Installation Requirements
Requires a redundant-capable backplane. Ensure sync cables are connected securely between the primary and secondary modules.
Usage Precautions
- Perform regular redundancy bump tests to verify failover functionality.
- Ensure adequate airflow around the module for cooling.
- Do not mix hardware revisions in a redundant pair.
