Weight: Approximately 1.50 kg (Net module weight)
Cooling Mechanism: Natural air convection (Highly efficient fan-less design)
Logistics & Compliance
Country of Origin: Japan
HS Code (Customs Code): 8538900000 (Parts suitable for use solely or principally with industrial electrical control panels, PLC systems, and boards)
Environmental Limits
Operating Temperature: 0°C to +60°C (32°F to 140°F) under standard conditions; extended ranges available up to 70°C for selective deployments
Storage Temperature: -40°C to +85°C (-40°F to 185°F)
Relative Humidity: 5% to 95% (Non-condensing)
Maximum Altitude: Up to 2000 meters above sea level
Regulatory Approvals: Complies with CE, UL, and CSA electrical safety and electromagnetic compatibility (EMC) standards
Key Product Features
Fault-Tolerant Redundancy: Provides automatic, high-speed failover switch times of 50 ms or less for CPU processing, power inputs, and communication interfaces to completely mitigate single points of failure.
Hot-Swappable Maintenance: Allows field technicians to safely swap modules online without halting active control processes, dramatically cutting maintenance overhead.
Deterministic Performance: Supports multi-task programming layouts with up to 16 tasks and minimum task execution cycles starting down at 5 ms for precise, predictable timing loops.
RAS Integration: Embedded with an advanced Reliability, Availability, and Serviceability (RAS) suite featuring CPU self-diagnostics, continuous module temperature tracking, and continuous I/O status feedback.
