Working Principle: The termination assembly receives analog signals from field devices such as transmitters and sensors. Each of the 16 channels passes the analog signal through a protective fuse to the connected T9431 or T9432 analog input module. The commoned ground configuration simplifies wiring by sharing a single ground reference across all channels. LED indicators provide visual confirmation of channel status.

  • Mount on DIN rail in industrial enclosure
  • Connect to T9431 or T9432 analog input module
  • Ensure proper grounding of common ground bus
  • Verify signal polarity for current loop connections
  • Install in clean, dry environment

Usage Precautions:

  • Non-isolated inputs require careful grounding management
  • Verify fuse integrity during maintenance
  • Do not exceed 24 mA maximum input current
  • Ensure proper signal shield grounding
  • Monitor LED indicators for fault detection
  • Replace fuses with correct 5 mA rating only
