Overview Manuals Applications Performance & Efficiency Configuration Environmental Ratings

Features:

  • Accepts analog measurements through model-specific Tri-GP baseplates.
  • Supports triplicated conversion and voted controller data.
  • Works with direct, conditioned, hazardous-location and HART interface options.
This product is the 3351S2 analog-input module common to several Tri-GP v2 input TriPaks.

Its baseplate and optional conditioning hardware establish the usable signal and field-termination method.

Correct replacement requires matching that interface, the address plug, loop scaling and project channel configuration.

Availability is subject to Apter Power inventory and sourcing confirmation.

  • Acquires transmitter signals for process supervision and control calculations.
  • Connects temperature sensors through the approved RTD/thermocouple termination arrangement.
  • Preserves HART access when paired with the designated HART baseplate and multiplexer.
  • Triplicated measurement paths provide voted analog data to the controller application.
  • Channel diagnostics identify internal abnormalities while preserving the supported fault-tolerant behavior.
  • Useful accuracy depends on the selected range, conditioning module, sensor wiring and grounding practice.
  • The project channel range must agree with the installed baseplate and conditioning hardware.
  • RTD, thermocouple and 4–20 mA service use the documented 2352S2 termination arrangement.
  • HART installations require the matching baseplate, multiplexer and communication wiring.
  • Standard modules operate inside an industrial enclosure under the Tri-GP environmental limits.
  • Hazardous-location loops require the specifically approved baseplate or external termination panel.
  • Shielding, protective earth and separation from noisy conductors protect low-level analog measurements.
Description
Triconex 3351S2 provides the analog acquisition engine used across several Tri-GP v2 input assemblies. The selected baseplate determines whether the field interface is direct analog, RTD/thermocouple conditioning, hazardous-location termination or HART multiplexing. Three independent analog paths acquire each signal and deliver separate data to the main processors for voting within the Tri-GP v2 architecture.

Independent channel electronics sample field measurements and pass values through the triplicated controller path for application use. Diagnostic routines monitor channel operation so maintenance can distinguish a localized internal problem from a complete loss of the input function. Direct, temperature, current-loop and HART applications are supported through distinct baseplate and termination families rather than one universal wiring board.

Order the module only after the installed baseplate and signal-conditioning arrangement are identified. Sensor type, range, grounding, shield termination and any HART multiplexer must remain consistent with the validated loop design. Continuous diagnostics and system hot-spare procedures support maintenance, while mechanical keying helps prevent an incompatible module/baseplate pairing.

Technical notes
3351S2 range and sensor behavior are defined by its baseplate and conditioning modules; verify those assemblies before moving any analog loop.
