Applications
- Analog signal acquisition: The module supports analog voltage and current measurement, including connection of 2-wire and 4-wire transducers for current measurement.
Key Features
- 8 isolated analog inputs: The module has 8 analog inputs for voltage and current signals. The channels are not isolated from one another, but are isolated from the backplane bus and electronics power supply.
- Supported signal ranges: Voltage ranges include 1 V to 5 V, -1 V to +1 V, -10 V to +10 V, -5 V to +5 V, -500 mV to +500 mV, and -80 mV to +80 mV. Current ranges include 0 to 20 mA, -20 mA to +20 mA, and 4 mA to 20 mA.
- 14-bit resolution: Resolution with overrange is 14 bit; unipolar resolution is 14 bit and bipolar resolution is 13 bit + sign.
- Diagnostics and alarms: The module has diagnostics, readable diagnostic information, a parameterizable diagnostic alarm, and a parameterizable limit value alarm for channels 0 and 2. Group error SF indication is provided by a red LED.
- 24 V supply and 20-pin connection: Rated load voltage L+ is 24 V DC, with reverse polarity protection. The required front connector is 20-pin.
- Isochronous mode and dimensions: Isochronous mode is supported. The module measures 40 mm wide, 125 mm high, and 117 mm deep, with an approximate weight of 230 g.
