Application Areas and Use Cases
Oil and Gas: Deployed in offshore platforms to maintain continuous control of wellhead valves and pumps. A North Sea rig reduced shutdowns by 95% after adopting IC698CRE040-HN, saving $2M annually.
Power Generation: Ensures uninterrupted monitoring of steam turbines in thermal power plants, preventing grid instability.
Water/Wastewater: Redundant control of sewage treatment pumps in urban systems, avoiding environmental incidents.
IC698CRE040-HN
Competitor Comparison
The IC698CRE040-HN outperforms comparable redundant modules through:
Faster Failover: <20 ms vs. industry-standard 50–100 ms for most alternatives.
Higher Temperature Tolerance: Operates 20°C hotter than competitors’ typical 50°C max.
Native EtherNet/IP Support: Eliminates need for protocol gateways, reducing hardware costs by 15%.
Selection Recommendations
System Criticality: Choose this module for systems where downtime costs >$10k/hour (e.g., oil refineries).
Scalability: Pair with IC698CHS030 controllers for >500 I/O points; use IC698CRE020 for smaller systems.
Budget: While 10–15% pricier than non-redundant modules, its ROI is realized within 6 months for high-risk applications.
Precautions
Installation:
Use anti-static wrist straps to avoid ESD damage during installation.
Ensure equal cable lengths between primary/secondary controllers for synchronization accuracy.
Maintenance:
Verify controller synchronization weekly via Proficy software.
Replace batteries every 5 years to maintain program memory.
Safety:
Power off both controllers before replacing the module to avoid voltage spikes.
Test failover procedures quarterly to validate redundancy logic.
