Applications
- Analog signal measurement: Measures voltage, current, thermocouple, resistance thermometer, and resistance signals through its analog inputs.
- Temperature measurement: Measures thermocouple and resistance thermometer signals with parameterizable temperature compensation and characteristic linearization.
- Diagnostic monitoring: Provides parameterizable diagnostics, diagnostic alarms, limit value alarms, readable diagnostic information, and a Group error SF LED.
Key Features
- Analog input channels: 8 analog inputs with support for voltage, current, thermocouple, resistance thermometer, and resistance measurement.
- Signal ranges: Supported rated ranges include 1 V to 5 V, -1 V to +1 V, -10 V to +10 V, 0 to 20 mA, 4 mA to 20 mA, and -20 mA to +20 mA.
- Resolution and conversion: Resolution with overrange is max. 15 bit; parameterizable integration time is 2,5 / 16,67 / 20 / 100 ms.
