Key Features

• Wide output range for current, voltage, and HART-enabled devices
• High-resolution performance with 16-bit precision
• Hot-swappable via RTB base (with field power off)
• Supports hot-swapping and is factory sealed for harsh environments

Compatible Components & Accessories

• 5094‑MBXT chassis and RTB3/RTB3XT terminal bases
• 5094‑STB shield bar (recommended for analog noise control)
• Studio 5000 Logix Designer for configuration and HART setup
• CompactLogix or Flex 5000 controllers via backplane

Industry Applications

• Process and loop control in chemical, energy, and manufacturing
• HART device integration and advanced diagnostics
• Rugged analog control in harsh or hazardous environments

Installation & Maintenance Notes

• Field-side power (SA) must be 18–32 V DC; remove before hot swap
• Use shielded twisted-pair cable (e.g., Belden 8761) for analog outputs
• Ensure conformal-coated slots remain sealed when not in use
• Use RAUP-enabled terminal base for safe in-service removal
