The MELSEC iQ-R Series offers integrated Functional Safety up to SIL3 / PLe, enabling you to control standard automation and safety logic in a single platform.
- SIL3 / PLe Certified Safety CPUs – Centralized or distributed safety control in the same rack as your standard CPU
- Local Safety Digital I/O – Connect safety devices directly to the CPU for high-speed, deterministic response
- Remote Safety Digital I/O – Extend safety zones via CC-Link IE TSN Safety without compromising cycle times
- Flexible zoning – Stop only the hazardous part of the machine while keeping the rest in operation
- Drive-level safety functions – Integrated over the network (STO, SLS, SS1) to protect operators while minimizing downtime
Why it matters: Functional Safety in iQ-R means less wiring, fewer separate controllers, and simplified programming. Safety and standard control share the same engineering environment (GX Works3), reducing project complexity while maintaining the highest safety performance.
