Working Principle:
The KJ3223X1-EA1 receives DC input power (12 VDC or 24 VDC) from the system power distribution. Internal switching power supply circuitry converts this input to the regulated +5.1 VDC and +3.4 VDC outputs required by DeltaV system components. The module provides electrical isolation between input and output circuits for safety and noise immunity. Output voltage regulation maintains precise voltage levels despite input voltage variations and load changes. The module operates continuously without requiring calibration or adjustment, and the sealed design prevents contamination and ensures long-term reliability.

Installation Requirements:

  • Install in DeltaV system carrier or power distribution panel
  • Connect input power within specified voltage range (12 VDC or 24 VDC)
  • Connect output wiring to DeltaV components requiring power
  • Ensure proper grounding
  • Verify input voltage does not exceed 12.6 VDC in pass-through mode
  • Follow DeltaV power distribution installation guidelines
  • Ensure adequate ventilation for heat dissipation

Usage Precautions:

  • Only qualified personnel should install the power supply module
  • Verify input voltage is within specified range before applying power
  • Do not exceed maximum current ratings
  • Do not attempt to disassemble or repair the module (no user-serviceable parts)
  • Follow hazardous area installation requirements if applicable
  • Monitor module operation for proper voltage output
  • Ensure operating temperature is within -40°C to +70°C range
  • Do not insert or remove module with power applied
  • Document power distribution configuration
