XTR116UA/2K5

The XTR116UA/2K5 is a precision current-output transmitter designed for industrial applications. It converts voltage inputs into a 4-20mA current loop signal, ideal for harsh environments due to its high accuracy and robust performance.
Key features:
- 4-20mA current loop output with low drift (0.01%/°C).
- Integrated voltage regulator (5V, up to 20mA) for powering external sensors.
- Wide supply range (7.5V to 36V), suitable for loop-powered systems.
- High precision (±0.05% nonlinearity) and low quiescent current.
Applications include process control, sensor signal conditioning, and industrial automation. The /2K5 suffix indicates tape-and-reel packaging for automated assembly.
