Primary Function: The transmitter takes the variable resistance signal from a 3-terminal linear potentiometer (often used as a displacement transducer) and converts it into standard, noise-immune industrial analog signals: $0?10V$ or $0/4?20mA$.

Key Role in Automation: In industrial and commercial automation systems, the TR-100 is essential for:

1. Signal Conditioning: Amplifying and filtering the raw, high-impedance resistance signal from the sensor.
2. Signal Standardization: Transforming the resistance value into widely compatible voltage or current signals, allowing for reliable long-distance transmission without degradation.
3. High Accuracy: It is known for its high precision, featuring an accuracy of $\pm 0.1\%$ Full Scale and extremely low non-linearity, which is critical for accurate position control applications like injection molding or hydraulic press monitoring.

Design: The unit is designed for permanent installation on a DIN-35mm rail in control cabinets, requiring a $24VDC$ power supply and incorporating features like wrong polarity protection and grounding isolation for robust industrial performance.
