TTF300 temperature transmitter: sensor inputs, output protocol and redundancy
TTF300 is an ABB field-mount temperature transmitter using two-wire technology. ABB describes two universal sensor inputs for RTD, thermocouple, resistance and millivolt signals, with HART, PROFIBUS PA or FOUNDATION Fieldbus versions. The listed configuration string is retained for identification; exact input wiring, output protocol, approval and enclosure option must be verified from the label and order record before replacement.

The values above are intended to identify the listed version and support an initial technical review. Confirm applicable standards, rating conditions, installed accessories and the current ABB documentation for the serial number or revision before design approval, replacement or commissioning.
Application and engineering focus
Match the transmitter input to the sensor type, element count, lead arrangement and measurement range. For dual sensors, decide whether the application uses backup, redundancy switching or differential measurement and check the parameterization. Sensor extension wire, grounding and thermowell response contribute to loop performance. A family accuracy specification does not include sensor tolerance, installation error or calibration uncertainty.
Configuration, compatibility and related references
Confirm whether the supplied device is HART or fieldbus and match it to the host, loop power and device description. Review hazardous-area certificates, enclosure material, display and safety approvals for the exact variant. For any SIL-related use, check the safety manual and certificate for the specific protocol and hardware revision; a family capability is not a blanket certification for every configuration.

Installation and commissioning checks
Wire the sensor with the correct polarity and lead compensation, then verify shield termination and electrical isolation according to the installation manual. Check thermowell insertion, ambient temperature and cable gland sealing. During commissioning, configure sensor type, range, damping, failure direction and output scaling. Compare the reading with a calibrated temperature source or reference and check diagnostics before returning the process loop to service.
During commissioning, verify the nameplate, configuration, wiring and diagnostics before enabling normal operation. Test the relevant signal path or protection response end to end under controlled conditions. Record settings and as-left measurements, and investigate abnormal values at the sensor, load, wiring or system configuration before replacing components.
Ordering, replacement and application information
For a quotation or replacement review, provide the complete designation TTF300-E1.C.1.H.BS, ABB order code where available, serial or hardware revision, quantity, installation environment, connected equipment, interface requirements and target delivery date. Include a clear rating-label photograph and relevant wiring, loop or panel drawing when possible.
Ask the supplier to confirm the exact configuration, accessories, revision and any approved successor in writing. Do not select solely from a family name or product photograph. For safety, grid-protection, medium-voltage or regulated applications, obtain review by the responsible qualified engineer and follow local codes and the manufacturer’s instructions.
