Series Overview
Part of GE’s RX3i High-Availability Series:
- IS415UCVGH1A: Redundant CPU module (V7666-111000 = firmware bundle).
- IC695PSA140: 40W redundant power supply.
- IC694ACC901: RX3i redundant backplane.
- IS420ESWBH3A: Ethernet safety switch.
Applications
- Power Generation: Turbine control backup systems.
- Oil & Gas: Subsea control pods & pipeline SCADA.
- Chemical Plants: Batch reactor safety interlocks.
- Water Treatment: Critical pump station control.
- Transportation: Tunnel ventilation control (SIL 2).
Functional Role
- Continuous Operation: Maintains control during CPU faults/maintenance.
- Data Integrity: Mirrored memory ensures no data loss during failover.
- Safety Logic Execution: Runs SIL 2 safety programs (e.g., burner management).
- Secure Remote Access: Supports VPN tunnels for encrypted engineering access.
Why Choose IS415UCVGH1A?
- Zero Downtime: >99.999% uptime with redundant architecture.
- Scalable I/O: Supports up to 512 modules via RX3i backplane.
- Legacy Integration: Compatible with VersaMax/Series 90-30 I/O.
- Lifecycle Management: 15-year product support guarantee.
- Migration Path: Direct replacement for IC695CPE310 CPUs.
Critical Notes:
- Requires redundant power supplies (e.g., IC695PSA140 + IC695PSB140) for full failover.
- SIL 2 compliance needs certified logic (GE Safety Builder v9.5+).
- Firmware V7666-111000 includes CVE-2024 patched libraries.
