Industrial Redundancy Solution – GE IC695CRH039 | PACSystems RX3i Series
Where This Product Is Used
The GE IC695CRH039 is a hot-standby CPU redundancy module engineered for mission-critical industrial automation environments where unplanned downtime is unacceptable. Typical deployment scenarios include:
- Oil & Gas Processing Plants – Pipeline SCADA systems, compressor station control, and wellhead automation requiring continuous 24/7 operation.
- Power Generation & Utilities – Turbine control, substation automation, and grid-tie protection systems where a single controller failure can trigger cascading outages.
- Water & Wastewater Treatment – Pump station control and chemical dosing systems mandating high-availability PLC architectures per IEC 61511.
- Pharmaceutical & Food Manufacturing – FDA-regulated batch processes and CIP/SIP systems where controller switchover must be bumpless and audit-traceable.
- Automotive Assembly Lines – Body-in-white welding cells and paint-shop conveyors where line stoppages carry six-figure-per-hour cost penalties.
- Chemical & Petrochemical Facilities – Reactor control and safety-instrumented systems (SIS) requiring redundant logic execution.

Why Engineers Specify This Model
- Bumpless Hot-Standby Switchover – The IC695CRH039 synchronizes primary and secondary CPUs in real time. Upon primary failure, the secondary assumes control in <10 ms with zero process disruption.
- 64 MB User Memory – Accommodates large, complex ladder/FBD programs, extensive data logging, and recipe management without memory constraints.
- Native EtherNet/IP & Modbus TCP – Eliminates the need for separate communication modules in most topologies, reducing BOM cost and panel footprint.
- IEC 61131-3 Multi-Language Support – Engineers can mix Ladder Diagram, Function Block Diagram, and Structured Text within a single project, maximizing code reuse.
- Proficy Machine Edition Integration – Full online editing, live variable monitoring, and firmware updates without taking the system offline.
- Proven RX3i Ecosystem – Drop-in compatible with the broad GE PACSystems RX3i I/O and communication module library, protecting existing capital investment.

Application-Specific FAQ
Q: Can the IC695CRH039 replace an IC695CPU320 in an existing RX3i rack?
A: The IC695CRH039 is a redundancy-specific CPU module and requires a paired redundancy configuration. It is not a direct drop-in replacement for a standalone IC695CPU320. A system redesign with dual backplanes and RMX modules is required.
Q: What is the maximum switchover time in a hot-standby configuration?
A: GE specifies bumpless switchover with typical transfer times under 10 ms, ensuring most process control loops experience no detectable disturbance.
Q: Is Proficy Machine Edition required for programming?
A: Yes. The IC695CRH039 is programmed exclusively via GE Proficy Machine Edition (PME). PME supports all IEC 61131-3 languages and provides online editing capabilities.
Q: Does this module support EtherNet/IP Class 1 (I/O) connections?
A: Yes. The RX3i CPU supports EtherNet/IP adapter and scanner functionality, enabling direct integration with Allen-Bradley I/O and third-party EtherNet/IP devices.
Q: What warranty applies to this product?
A: Konmask.com provides a 90-day functional warranty on all modules. Extended warranty and repair services are available — contact support for details.
