Applications
- Analog signal measurement: Measures voltage, current, resistance and resistance thermometer signals through its analog inputs.
- Two-wire current measurement: Connects 2-wire current transducers when an external supply is used.
- Resistance measurement: Performs resistance measurement with two-wire, three-wire or four-wire connections.
Key Features
- 8 analog inputs: Has 8 analog inputs for voltage, current, resistance and resistance thermometer measurement; the analog inputs are not isolated from each other but are isolated from the backplane bus.
- Supported input ranges: Supports voltage ranges 0 to +10 V, 1 V to 5 V, -1 V to +1 V, -10 V to +10 V, -5 V to +5 V, -50 mV to +50 mV and -500 mV to +500 mV; current ranges 0 to 20 mA, -20 mA to +20 mA and 4 mA to 20 mA.
- Resistance thermometer inputs: Supports Ni 100, Ni 1000, LG-Ni 1000 and Pt 100 resistance thermometers with Standard/climate options as supplied.
- Resolution and conversion: Provides 13 bit resolution with overrange including sign, parameterizable integration time of 60 / 50 ms and basic conversion time of 66 / 55 ms.
- Signal connections: Supports voltage measurement, current measurement with 2-wire transducers with external supply, 4-wire transducers, and resistance measurement with two-wire, three-wire or four-wire connections.
- Conformal coating and connection: Has conformal coating, a 1x 40-pole connection, 90 mA maximum input current from the 5 V DC backplane bus and typical power loss of 0.4 W.
