In order to ensure maximum system availability,POSEIDON is equipped with a large number of safety features and redundancy standards:
- Dual main power supply input
- Uninterruptible Power Supply (UPS)
- Dual redundant 24VDC power supply
- Redundant PLC
- Overcurrent circuit breakers
- 3-phase ring bus transformers
- FI fault current breaker
- Phase supervisor
In case of failure of one of the main components, the spare component takes over all functions. All ratings are oversized and POSEIDON accepts two independent shipsupplies. All critical power parts are independently fused and fully protected against overload and short circuits.
POSEIDON – „Hot-Standby“ PLC
Highest redundancy standard ensuring maximum system availability Two identical PLCs, including all associated in and output modules, operate in parallel, running the same software. A PLC supervision circuit monitors all activities of both PLCs in real-time. Should the main PLC fail or work incorrectly, the supervision circuit detects this state and automatically switches over all connected I/O circuits to the standby PLC, ensuring immediate system control after switch over.
