Applications
- Resistance measurement: Measures resistance using two-wire, three-wire, or four-wire signal-encoder connections.
- Temperature measurement: Measures temperature with supported resistance thermometers including Cu 10, Ni, and Pt types.
- Input diagnostics: Provides wire-break, group-error, and overflow/underflow diagnostics for the analog inputs.
Key Features
- Analog inputs: 2 analog inputs support resistance thermometers including Cu 10, Ni 100, Ni 1000, Ni 120, Ni 200, Ni 500, Pt 100, Pt 1000, Pt 200, and Pt 500.
- Resistor input ranges: Rated resistor ranges include 0 to 150 ohms, 0 to 300 ohms, 0 to 600 ohms, and 0 to 3000 ohms.
- Supply and current: Load voltage L+ is 24 V rated, from the power module. Input current is max. 30 mA from load voltage L+ without load and max. 10 mA from the 3.3 V DC backplane bus.
- Measurement and resolution: The measurement principle is integrating (Sigma-Delta). Resolution with overrange is max. 16 bit; for specified RTDs it is 15 bit + sign, for resistor ranges it is 15 bit, and for PTC it is 1 bit.
- Diagnostics and isolation: Diagnostics include wire break, group error, and overflow/underflow. The analog inputs are isolated from the backplane bus and load voltage L+; isolation is tested with 500 V DC.
- Connection and coating: Two-wire, three-wire with internal line-resistance compensation, and four-wire resistance measurement are supported. Shielded cable length is max. 200 m, and the module has conformal coating.
