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.
