  • Network Speed: 100Mbps fiber optic Ethernet for Foxboro Evo control network.
  • Environmental Rating: G3-class harsh environment compliant.

Material Composition
Enclosed in a rugged die-cast aluminum housing providing superior EMI shielding and thermal dissipation, with internally conformal-coated PCBs.

Structural Characteristics

  • Dimensions: 140mm × 165mm × 45mm.
  • Weight: 0.6kg.
  • Protection: IP20 rated.

Working Principle
The RISC processor continuously scans field inputs via the high-speed bus, executes sophisticated control algorithms in real-time, outputs commands to actuators, and synchronizes data across the redundant fiber optic network.

Installation Requirements

  • Must be securely seated in an I/A Series compliant control rack.
  • Redundant 24VDC power supplies are required for hot-standby operation.
  • Ambient temperature must be strictly maintained between 0℃ and 60℃.

Usage Precautions

  • Never forcibly remove the processor while energized.
  • Always perform a full system backup before executing firmware upgrades.
  • Regularly clean air filters and cooling channels to prevent thermal throttling.
