      Overview Manuals Common Applications Product Precautions
      Honeywell TA3840C provides a control-room hub for fixed marine gauging. Its 19-inch rack combines power, processing, operator display and configurable signal boards for tank measurement and alarm presentation.
      • Up to 64 cargo tanks
      • Up to 96 auxiliary instrument inputs
      • EMS and Modbus RTU output
      • 12U and 21U rack versions

      Use the archived vessel configuration to rebuild channel mapping and calculation settings, then compare local rack values with the loading computer and connected monitoring system before handover.

      Important Notice: Match the TA3840C rack size, board population, field interfaces and vessel configuration before replacement or commissioning.

      Honeywell TA3840C Technical Reference (PDF)Honeywell TA3840C Installation & Commissioning Guide (PDF)

      The Technical Reference consolidates rack architecture, signal capacity, communication paths and operating limits. The Installation & Commissioning Guide organizes isolation, configuration capture, connection checks and staged vessel-system acceptance.

      Cargo tank monitoring
      Combines ullage, level, pressure and temperature measurements for cargo visibility.
      Ballast management
      Processes ballast, draft, trim and heel signals used to monitor vessel balance.
      Loading-computer integration
      Provides calculated tank data to connected shipboard loading and gauging software.
      Control-room indication
      Presents measurement and alarm information locally on the rack display.
      Apply these controls specifically to Honeywell TA3840C before isolation, replacement, reconnection and final release.
      1
      Match the complete TA3840C identity and installed rack height before planning replacement work.
      2
      Back up channel assignments, serial settings and tank-calculation configuration before isolation.
      3
      Identify every connected sensor, analog board and multifunction I/O board against the ship drawing.
      4
      Isolate rack power and confirm absence of hazardous energy before accessing internal boards.
      5
      Use grounded ESD controls when handling the central processing or interface assemblies.
      6
      Check EMS and Modbus RTU wiring, polarity, shielding and termination before energization.
      7
      Commission tank channels with known input conditions and compare displayed values with the loading system.
      8
      Verify alarms, serial communication, on/off outputs and final vessel-system status before handover.
