Mitsubishi Electric Launches MELSEC iQ-R Series IEC 61508 SIL 2-compliant Redundant Programmable Controller

Mitsubishi Electric Corporation announced that it will launch its newest MELSEC iQ-R Series general-purpose programmable controller, the IEC 61508 SIL 2-compliant redundant programmable controller paired with a redundant-function SIL2 CPU set for high performance and extra reliability, on October 31. To help reduce total cost of ownership (TCO), the system integrates detectors and controllers for monitoring and management and a safety programmable controller compliant with international safety standards.

Product Features

Compliant with international safety standards Compliant with IEC 61508 SIL 2, which is required for infrastructure systems, and has been certified by TÜV Rheinland to meet global needs Integrated process control and safety control realizes TCO reduction GX Works3 engineering software integrates process- and safety-control programming Enables execution of integrated process- and safety-control programs with a single CPU module (to execute generic control programs sequentially), thereby helping to reduce total cost of ownership Redundant configuration realizes highly reliable system Redundant basic system (SIL2 CPU set1, power supply module, basic base unit, network module) ensures continuous operation by switching to standby if error occurs in control system 1SIL2-process CPU module and SIL2-function module included as set. Can only be used in redundant configuration
