Product Description
Key Features
- Exact product identity: SIMATIC S7-1200 G2 SB 1231 RTD, AI 2x 16-bit RTD.
- Resistance-thermometer inputs: 2 analog inputs support resistance thermometers including Pt100, Pt1000, Ni100, Ni1000, Ni120, Ni200, Ni500, Cu10, Cu50, Cu100 and LG-Ni1000.
- Input resolution and measurement: Integrating measurement principle with 15 bit resolution including sign; integration time and measured-value smoothing are parameterizable.
- Electrical and protection data: Input current from the backplane bus is 20 mA typical, power loss is 0.1 W typical, and protection degree is IP20.
Applications
- Temperature measurement: Measures temperature using resistance thermometers with adjustable degrees Celsius or degrees Fahrenheit.
