Description
The ifm TA series are programmable 2-wire temperature transmitters designed to accept RTD (Pt100/Pt1000) or thermocouple inputs from a temperature sensor and convert them to a linearized 4–20 mA analog signal for PLC/SCADA analog input cards. Models such as TA2002 (standard programmable via PC/keypad), TA1602/TA1605/TA1612 (compact/economy versions), and TA2012/TA2105/TA2107 (enhanced features, HART optional on some) cover a wide range of process temperature monitoring applications in food & beverage, pharma, water treatment, and machine building.
Key Features
- Input: Pt100 (2/3/4-wire), Pt1000, Ni100, Thermocouple types J/K/T (model dependent — check suffix)
- Output: 4–20 mA (2-wire loop-powered, 24V DC loop required)
- Configuration: Via ifm “moneo” / LR DEVICE software over IO-Link (on smart versions) or built-in 3-button keypad + LCD (TA2002/TA2012)
- Measuring Range: User-programmable (e.g., -50…+150 °C or any span within sensor limits)
- Accuracy: Typically ≤ ±0.1 % of span + sensor error
- Sensor Break / Wire Break Detection: Yes — drives output to < 3.6 mA or > 22 mA on fault
- Country of Origin: Germany
