Applications
- Analog signal acquisition: The module supports voltage measurement, current measurement with 2-wire transducers using an external transmitter, and current measurement with 4-wire transducers.
Key Features
- 8 analog inputs: The module has 8 analog inputs for voltage and current measurement.
- Supported signal ranges: Supported rated ranges include 1 V to 5 V, -10 V to +10 V, -5 V to +5 V, 0 to 20 mA, -20 mA to +20 mA, and 4 mA to 20 mA.
- 16 bit resolution: Resolution with overrange is up to 16 bit; integration time is parameterizable at 10/ 16.67/ 20/ 100 ms.
- Diagnostics and alarms: The module has parameterizable diagnostics, diagnostic alarms, limit value alarms on channels 0 and 2, readable diagnostic information, and a red group error SF LED.
- Isolation and grounding: The analog inputs are isolated from the backplane bus and have single-point grounding; isolation is tested with 500 V DC. Channels are not isolated from one another and are arranged in groups of 2.
- 40-pin connection: A 40-pin front connector is required. Dimensions are 40 mm wide, 125 mm high, and 117 mm deep; weight is approximately 272 g.
