Applications
- Analog signal measurement: Measures voltage, resistance, resistance thermometer, and thermocouple signals through its analog input channels.
- Signal diagnostics: Monitors supply voltage, wire breaks for TC, R, and RTD, limit values, overflow/underflow, and channel or module diagnostics.
Key Features
- Analog input channels: 8 analog inputs support voltage, resistance, resistance thermometer, and thermocouple measurement, plus one additional RTD reference channel.
- Signal ranges: Supported ranges include -1 V to +1 V, -25 mV to +25 mV, -250 mV to +250 mV, -50 mV to +50 mV, -500 mV to +500 mV, and -80 mV to +80 mV; 4 mA to 20 mA is not supported.
- Resolution and accuracy: Analog input resolution is 16-bit, with 0.1% accuracy and 21 bit resolution with overrange for RTC and TC measuring modes when using the scalable temperature measuring range.
