Product information
Overview
Key Features
- RTD analog inputs: Has 2 analog inputs for resistance thermometers, including Pt10, Pt50, Pt100, Pt200, Pt500, Pt1000, Ni100, Ni120, Ni200, Ni500, Ni1000, Cu10, Cu50, Cu100, and LG-Ni1000.
- 16-bit input resolution: Provides maximum 15 bit resolution with overrange, including sign, and uses an integrating measurement principle.
- Configurable measurement: Temperature measurement units are adjustable to degrees Celsius or degrees Fahrenheit; integration time and measured-value smoothing are parameterizable.
- Diagnostics and alarms: Has alarms, diagnostic alarms, readable diagnostics, wire-break detection, and a DIAG LED for input status.
- Electrical and mechanical data: Input current from the backplane bus is typically 20 mA at 5 V DC, typical power loss is 0.1 W, and protection is IP20.
