Selection Guide
-
Performance Needs:
- Choose IC695CRU320-EJ for standard applications; upgrade to IC695CRU420-EJ (1 GHz) for AI/ML edge processing.
- Verify I/O count: 1,024 points suffice for 90% of manufacturing lines.
-
Redundancy Requirements:
- Opt for the -R variant (IC695CRU320-EJ-R) for systems requiring <100 ms failover (e.g., oil refineries).
- Non-redundant models save 25% in cost for non-critical processes.
-
Environmental Factors:
- Select the -H variant (IC695CRU320-EJ-H) for IP67-rated outdoor use (e.g., water treatment).
- Ensure 5 cm airflow in enclosures exceeding 40°C.
Installation and Maintenance Tips
-
Installation:
- Use anti-static wrist straps; torque rack screws to 1.2 N·m (10.6 lbf·in).
- Configure redundant pairs via GE Proficy Machine Edition (PME) software.
-
Maintenance:
- Replace internal battery every 7 years (maintains RTC and program memory).
- Schedule quarterly firmware updates (latest v8.2+ fixes 20+ security vulnerabilities).
-
Safety:
- Power down all racks before replacing CPUs to avoid ESD damage.
- Follow NEC 501 for hazardous location installations (Class I, Div 2).
