Product information
Overview
Applications
- Voltage and current measurement: Supports voltage measurement and current measurement with 2-wire transducers with external supply or 4-wire transducers.
- Resistance and temperature measurement: Supports resistance measurement with two-wire, three-wire or four-wire connections and resistance thermometer measurement including Pt100, Ni100, Ni1000 and LG-Ni1000.
Key Features
- 8 isolated analog inputs: Has 8 analog inputs and potential separation between the analog inputs and backplane bus; the channels are not isolated from each other.
- Supported signal ranges: Supports voltage, current, resistance and resistance thermometer inputs, including 0 to +10 V, 1 V to 5 V, 0 to 20 mA, 4 mA to 20 mA, Pt100, Ni100, Ni1000, LG-Ni1000, 0 to 600 ohms and 0 to 6000 ohms.
- 13-bit resolution: Resolution with overrange, including sign, is max. 13 bit. Integration time is parameterizable at 60 / 50 ms.
- Conversion and interference suppression: Basic conversion time is 66 / 55 ms, with interference voltage suppression for 50 / 60 Hz.
- Signal encoder connections: Supports voltage measurement, current measurement with 2-wire transducers with external supply, 4-wire transducers, and resistance measurement with two-wire, three-wire and four-wire connections.
- 40-pin front connection: Requires a 40-pin front connector. Dimensions are 40 mm wide, 125 mm high and 117 mm deep; approximate weight is 250 g.
