Applications
- Current measurement: The module supports current measurement with 2-wire transducers using an external supply and with 4-wire transducers.
- Input diagnostics: The module provides diagnostic alarms, limit value alarms, wire-break detection for 4 … 20 mA, and channel and module diagnostic indications.
Key Features
- Analog current inputs: 16 analog inputs support current measurement in 16 channels.
- Supported input ranges: Rated current ranges are 0 to 20 mA, -20 mA to +20 mA, and 4 mA to 20 mA.
- Resolution and conversion: Resolution with overrange is 16 bit; parameterizable integration times are 2,5 / 16,67 / 20 / 100 ms.
- Diagnostics and alarms: The module has diagnostics, diagnostic alarms, limit value alarms, wire-break detection for 4 … 20 mA, and overflow/underflow detection.
- Installation and connection: Delivery includes the infeed element, shield bracket, and shield terminal. The front connector with screw terminals or push-in must be ordered separately; shielded cable length is max. 800 m.
- Electrical separation: Isolation is tested with 707 V DC (type test). The permissible potential difference is 8 V DC between inputs and 4 V DC between inputs and MANA.
